Subjects

Personal Description:
I have a degree in Physics from the University of Nottingham and have taught Science in schools for over 8 years. I have a wide variety of teaching experience, from teaching English as a foreign language to a small group of 6 year olds, to teaching A level Physics in college. I love teaching and especially enjoy seeing students progress, become more confident and gain a real interest and love of the subject.

Teaching Experience:
I have now been tutoring for over 3 years, helping many students to gain the grades they require in their GCSE and A level exams for Science and Maths.

Previously, I spent 7 years living in Thailand where I taught both England (as a foreign language) and Science in an International Program at one of the top government schools. I also taught English, Maths and Science as a tutor, both on a one-to-one basis and to small groups.

I gained a PGCE in Secondary Science from Manchester Metropolitan University in 2009 and worked as a supply teacher in a number of secondary schools in the Cheshire area before becoming a full time tutor.

Tutoring Approach:
I like to encourage a love of the subject and take great joy in seeing students progress and become successful. I try to be friendly and supportive whilst also striving for excellent results. I try to make sessions interesting and informative by personalising the work to centre around the interests and needs of the individual student and by making use of ICT resources.

Personal Description:
**Fully booked until June 2026. However, I am taking enquiries for students wishing to start in June-September 2026**.

I am Dr. Clare, a full-time professional tutor, a current GCSE and A-level examiner, and a former University Lecturer in Pharmacy (University of Nottingham), as well as a past Vice-President of the professional body for private tuition.

I hold a PhD from Imperial College London and have a strong academic and research background. I have led cutting-edge projects for multinational pharmaceutical and biotechnology organisations, including Unilever, GlaxoSmithKline, Zeneca, and Novartis. My published research has been cited over 7000 times in peer-reviewed literature, and I currently serve on the editorial boards of several respected international scientific journals. My passion for science and mathematics, combined with real-world research experience, allows me to bring subjects to life and make complex ideas accessible and engaging.

Alongside my own tutoring, my son-an MEng student at Aston University-works with me as an employee of my business supporting GCSE students in Maths and Physics. He has full access to my teaching resources, holds a current DBS check, and offers sessions at £30 per hour.

I enjoy working with students of all ages and abilities, and I am committed to helping each individual reach their full potential. My teaching style is patient, supportive, and tailored to the unique strengths and needs of every learner.

With extensive experience as a tenured university lecturer, I have taught at both undergraduate and postgraduate levels and have supervised eight PhD students to successful completion. I have also interviewed numerous UCAS applicants and can provide expert guidance on crafting strong personal statements and preparing for university applications.

Teaching Experience:
My students consistently achieve outstanding results. At A-level, the most recent set of results were 100% A*-C grades, with 85% achieving A*-A, 8% B, and 7% C. Every student secured a place at their first-choice university, with 31% progressing to medical school. These results are consistent year-on-year. At GCSE (2025), students achieved 100% grades 9-7 on Higher Tier papers, and 100% grade 5 on Foundation Tier papers-the highest grade available at that level.

I have been a full-time professional tutor for over thirteen years and was elected Vice-President of The Tutors' Association, the UK's professional body for tutors-an acknowledgement of my standing within the profession.

I have extensive experience across all major examination boards, including AQA, OCR, Edexcel, IB, and CIE. As a current and highly experienced Biology examiner and question setter, I provide students with valuable insight into how marks are awarded and how to approach exams strategically from an examiner's perspective.

In addition to tutoring, I have recent secondary school teaching experience, ensuring my methods remain closely aligned with current curricula and classroom expectations.

I also have significant experience supporting students with a wide range of additional needs, including autism (and Asperger's), ADHD, dyslexia, and partial hearing. Furthermore, having lived and worked internationally, I am well equipped to support students for whom English is an additional language.

My experience allows me to adapt my teaching to suit each individual, helping students build confidence, master exam technique, and achieve their academic goals.

Tutoring Approach:
I deliver tuition either face to face (students travel to me), or online via Zoom.

Where students travel to me, I offer a dedicated quiet space for tuition free from distractions and with all of my resources and reference books to hand.

Online tuition is carried out via Zoom. Whilst some students are initially concerned that online will be impersonal, once experienced it tends to be the preferred option for many. It Online offers significant advantages: students can learn in a comfortable, familiar environment, avoid travel time and disruptions, and benefit from a more flexible and environmentally friendly approach.

Each session is supported with high-quality resources. Students receive a detailed AI-generated summary after every lesson, along with a PDF copy of all work completed on my interactive whiteboard-providing clear, structured notes to revisit and reinforce learning between sessions.

My teaching is highly personalised. Before tuition begins, we agree clear goals, and I design a tailored programme of study to meet the student's specific needs and aspirations. Progress is carefully monitored throughout, with ongoing assessment and adaptation to ensure each student continues to develop effectively and confidently.

Above all, I believe that learning should be engaging and enjoyable. I am approachable, supportive, and committed to creating a positive learning environment where students feel motivated and confident-because when students enjoy their learning, they achieve their very best.

Subjects

Personal Description:
I am a 34 year old Post doctoral researcher in the field of endocrinology.

My undergraduate degree (2010) was in Biology from Imperial College, London, where I continued to study to Masters level (2011) in Reproductive and Developmental Biology. between 2013-2016 I completed my PhD in reproductive endocrinology. therefore my knowledge of biology spans multiple subject areas.

I have A-levels in Biology, Physics, Maths and History and a keen interest in all of these subjects.

Having completed my PhD and fulfilled 3 post-doctoral research positions, I feel I have gained experience in the skills required at all levels of education to progress and succeed and would really like to help others to realise their academic talents and to succeed in their education.

Teaching Experience:
I am currently training for my postgraduate certificate of academic practice, for lecturing and small group teaching at undergraduate level.

I have been tutoring privately for the past 6 years and have successfully guided GCSE and A-Level students to achieve their goals, gaining further jobs through recommendation.

Throughout my career, I have been responsible for overseeing and training undergraduate students in the laboratory and ensuring they have a key understanding of protocols, the biology behind them and how to use this knowledge to work out problems for themselves. This also involves mathematics skills, such as fractions, dilutions and molar concentrations, as well as helping them with any biology questions they may have outside of the lab. I provide feedback on presentation skills and on key learning skills required at degree level.

I have also had experience teaching students at A-level stage, in a two part workshop surrounding the biology of genetics. A key component of this is helping them to understand a totally new subject and to answer any questions they have surrounding university applications, study skills and personal statements.

I like to think this broad range of experience has taught me to interact with students of various ages and to recognise learning approaches that work best for different individuals.

Tutoring Approach:
The most important thing to consider is a student's personal requirements and to find a learning style that works for them. People learn in different ways so to teach in a style that maintains interest and works for the individual student is really important to me.

a goal based approach is important in my eyes. to understand what need to be learnt, by when and to work through a strategic plan to achieve the best results for the student.

Subjects

Personal Description:
A first class Medical Sciences graduate and qualified teacher, I have over 7 years` experience in teaching/tuition.

Well-versed in most major exam boards, I am able to work successfully with students across all levels of attainment in order to further their understanding of core scientific principles and enhance their exam technique. My position as an assessment specialist with two of the major exam boards has enhanced further my understanding of how credit is awarded in exams - enabling me to not only improve students' subject knowledge, but to improve their approach to exam questions as well.

I take a positive and friendly approach to tuition, and am happy to be flexible in using the methods that best suit the student.

Teaching Experience:
I have been a private tutor since attending university in Exeter, and have helped students to improve on their grade by up to 3 boundaries.

I am a professional teacher, having trained through the prestigious Teach First programme. My progress was judged as outstanding. I have been consistently judged good/outstanding, both internally and by Ofsted, and have held a number of leadership positions.

Tutoring Approach:
Largely, this will depend on what the student is hoping to achieve. I appreciate that, most often, a student's aim is to achieve a certain grade in an exam. In these cases, I will spend a lot of time working with the student to familiarise them not only with the material for the exam, but with the format of the exam paper, exploring how to approach different types of question and working directly with mark schemes to best understand how credit is awarded.

I am, however, passionate about my subject, and aim to uncover some enthusiasm for the sciences with all my students, through engaging sessions in which we can explore topics in perhaps more detail than is often possible within schools.

Subjects

Personal Description:
I am an experienced science teacher available to tutor during evenings/weekends.

Teaching Experience:
I am in my eighth year of teaching Science up to GCSE level and I have a strong subject knowledge across all areas of Biology, Chemistry & Physics. I am very familiar with the new science specification (currently teaching AQA Trilogy) and the levels of knowledge required for KS3 and KS4.

Tutoring Approach:
My sessions can be adapted to specific needs and are planned to focus on areas of weakness identified. With KS3 (Years 7-8) I focus on working scientifically and key ideas in science, while I structure KS4 (Years 9-11) sessions around knowledge retrieval practice, linking scientific ideas and exam technique.

If you have any questions, please do not hesitate to contact me. I look forward to hearing from you.

Subjects

Personal Description:
My name is Ngum-Agnes, I am 18 years old. I live in Cardiff and am currently studying Mathematics, Biology, Chemistry and French at A level.
I received all As and A*s at GCSE and A Levels and all A*s in the subject I am tutoring in.
I like to think of myself as friendly, polite and patient.

Teaching Experience:
I have had tutoring experiencing in the UK for over a year now in French, English, Mathematics, and Science.

I recently volunteered at children's orphanage in Africa where, among other things, I taught the Ethiopian children English. Doing so taught me the effectiveness and importance of patience and empathy when tutoring, as well as giving the pupil time to think through things in their own way.

Tutoring Approach:
I make sure to explain things slowly yet effectively and take time to understand the pupils way of learning and adapt my teaching in that way. I ensure that I am patient and friendly when tutoring and try to create a relaxed and calm but attentive atmosphere. I like to create a bond with my student so that they feel comfortable when learning but also eager and unafraid to ask questions when they do not understand.

Personal Description:
My name is Kat, and I am a qualified nurse currently pursuing PhD study following working as a Practice Development Nurse at the John Radcliffe Hospital in Oxford.

I live in the beautiful village of Brill, Buckinghamshire, with my 2 year old son, and my husband who splits his time between Brill and Germany. We enjoy being outside, music and eating good food.

I have a passion for people, seeing them realise their potential and exceed their goals. I was a tutor with UK Tutors during my nursing training in 2010-2012, and can't wait to meet new some new tutees.

Teaching Experience:
I have had a range of education / developmental / teaching roles throughout my career, and through delivering education in a variety of settings and through different media I have gained skills which allow me to really focus on the needs of my individual tutees, their current levels of understanding and their end goals.

Personal Description:
I'm 26 and recently discovered my love for tutoring after volunteering to take responsibility for my nephew's home schooling during lockdown. I currently study at The Open University towards a BSci Hons Natural Sciences degree. I have first hand experience of being the student and the tutor and found this invaluable when working with my nephew towards his learning aims.

Teaching Experience:
One year zoom tutoring, KS2 and KS3, all subjects.

Tutoring Approach:
I work with a high level of emotional intelligence and feel the child is happiest and most open to learning without the pressure of feeling responsible for their learning. I will only use positive reinforcement to encourage learning and find having set prizes to earn to be very effective for motivation. What I take the most joy in is tailoring lesson content to the interest of the child, enabling the child to fully engage and enjoy my lessons rather than view them as a chore.

Personal Description:
I am a physics and maths teacher with 18 years teaching experience. I am passionate about helping pupils understand this fascinating subject so that they can reach their potential

Teaching Experience:
I have taught physics up and and including A level for 20 years. I have also taught maths up to GCSE for many years. I am a previous head of science & assistant headteacher. Previously, I am an examiner for OCR Physics at A level and WJEC for Science at GCSE and currently deliver the WJEC specification to students in Wales. I tutor pupils from all examination boards across the UK.

Please message me for any information on Maths or Science.

Tutoring Approach:
My approach to tutoring is to ensure students understand the areas of learning they are struggling with and build on that to ensure confidence in all areas of the course. I challenge pupils on what they already know to ensure it is correctly reinforced and their confidence grows. I tutor using reciprocal learning, where students are able to independently learn a topic and then have a tutorial style lesson where they reinforce that learning. Tutoring styles are always adapted to the needs of the learner which is very quickly established.

Personal Description:
Hey I'm Abdul. I'm currently studying Computer Science at the University of Leeds. I passed my 11+ and attended Wilson's School and I absolutely loved my time there. When studying for my GCSE's, I struggled quite a lot with Chemistry and so I decided to get a tutor. After a few months of receiving tuition, there was a noticeable improvement in my grades and I achieved a grade 9 in Chemistry GCSE and later on studied it for A-level and achieved a grade A. I was very thankful to my tutors and teachers as I could not have done well in my studies without them.

During my time at sixth form, I volunteered to tutor GCSE students in my school. I later on taught some students outside of school for 1 year and it allowed me to build a long term relationship with my students and be able to actually see improvements in their grades and confidence in that subject. This was an extremely rewarding feeling for me and is what motivates me as a tutor.

In my free time, I like to play badminton and spend time with friends and family.

Teaching Experience:
**Volunteer Mentor at Wilson's School (6 months) & Private Tutoring outside of school (2 years)**

- Regularly mentored GCSE students, personalising lessons based on individual needs and abilities, which improved their comprehension and academic performance. After around 3 months of this, the students confirmed they had seen at least a 1 grade improvement from grade 7's to grade 8's and 9's.
- Created a supportive and nurturing learning environment, instilling confidence and motivating students who initially struggled to see the value in their education

Tutoring Approach:
I ask my students about their weakest areas of subject knowledge and plan my lessons from there. Moreover, I engage with my students by asking them questions to ensure they are understanding everything. When showing them a subject specific question, I make sure it's from their exam board and is from past papers so they are able to answer similar questions in their exams.

Personal Description:
Hi, I'm Nicola - a final year graduate medical student at the University of St Andrews.
I have a BSc (Hons) in Biology also from the University of St Andrews.

Teaching Experience:
I have worked as a tutor for 5 years now, and I have tutored a variety of subjects and ages, from primary to SQA highers.

Tutoring Approach:
I teach sailing during the summers to children and adults alike, so I can quickly adjust topics and lessons to be suitable for different age ranges. I love working out how each individual learns best and strive to ensure everyone I teach reaches their full potential. I want to make the learning process fun and enjoyable, and not be seen as a chore! I tailor my lessons to the student's abilities and personality. I try to link the subject to their interests, as I believe that people learn best when they are interested in a subject and can see the relevance of what they're studying.
I have personally sat exams in both the Cambridge IGCSE and Scottish Higher/Advanced Higher syllabuses, so I understand both the exam boards themselves and how to research the specifics of new exam boards. Please don't hesitate to contact me if you have any questions!

Personal Description:
Hi, my name is Maahi, and I am currently a student at St Dominic's 6th form, studying Biology, Chemistry and Mathematics at a level. I received an outstanding set of GCSE grades and my set of results was even published in the school newspaper. I like helping younger students in any way possible, in year 10, I helped those who have come from foreign countries or have a lower reading level and have difficulty reading to become fluent readers through a 'reading buddies' programme. That was when I realised that I am good at teaching and helping students. After that I tutored the younger children in family and friends and helped them get amazing grades for SAT'S and gcse's and I want to extend this to everyone that wants to receive good grades and achieve their dreams. So now, i want to put my knowledge to some use- hence why i am here.

Teaching Experience:
I received 5 grade-8's in my Gcse's this year, including Biology, Chemistry, physics, maths, english literature, and 4 grade-7's in french, history, further maths, english language. My revision techniques are clearly effective and want to help students who want to learn and set their goals in life. I can also help with giving advice for a levels as I am currently studying biology, Chemistry and Mathematics at a level myself. There are multiple different ways to learn and I can help find the right way to learn for you. After having tutored many of my friends and family in the younger years, I realised that I have a passion for teaching as I can make even the most mediocre thing interesting and understandable. I am open to teaching online virtually, so you don't even have to travel anywhere- all at a reasonable price! Each lesson will be approximately an hour long, whenever at your convenience as long as I can find time on my schedule as well to teach.

Tutoring Approach:
I have previously had experience teaching younger children including cousins, family friends, younger students at my school, other tutoring companies.

Personal Description:
Hi! I'm Dudo-a cheerful and passionate medical student who's excited to help you succeed. I'm trilingual, fluent in English, Cantonese, and Mandarin. Having earned straight Grade 9s and 8s in my GCSEs and completed A-levels in the UK, I know what it takes to excel academically. I'm here to share the tips, strategies, and support that helped me thrive. I can't wait to meet you and support your learning journey!

Teaching Experience:
While I may not have extensive formal teaching experience, I bring a wealth of practical knowledge and proven strategies for tackling exams and tests-gained through my own academic journey. I've also spent a few months tutoring Year 7 students in mathematics, which gave me valuable insight into how to support learners effectively.

Tutoring Approach:
Want to achieve Grade 9? Consistent practice with past papers-it's that simple. Having earned straight 9s and 8s in my GCSE subjects, I understand how crucial it is to master not just the content, but the exam technique and strategy that help you "play the game" effectively.

My lesson style includes:
1. Initial group chat with students and parents: understand goals, expectations, and identify strengths and areas for improvement.
2. Pre-lesson preparation: I ask students to send me their school materials a week in advance so I can tailor the session to match their curriculum-ensuring lessons feel smooth and never overwhelming.
3. Lesson time!
4. Homework assignments: reinforce what we've covered.
5. Progress updates: I regularly share a summary of what we've covered in the group chat to keep everyone informed.

Subjects

Personal Description:
As a current A-level student, I aim to offer targeted tutoring for students currently doing their GCSE's, using my recent experience and knowledge of the curriculum to my advantage. All the subjects I offer I've achieved grades 7 and above in, with 9s in both English language and literature, and 8s in history and religious education. My main priority as a tutor is to help students understand exactly what the examiners are looking for, whilst providing insights and strategies from a student's perspective in the following subjects:
-English literature (AQA)
-English language (AQA)
-History (Edexcel)
-R.E (Eduquas/ wjec)
-Maths (Edexcel)
-Biology (AQA)
-Drama (AQA)

Teaching Experience:
Whilst I haven't held an official teaching role, I've spent the last couple of years helping to mentor those around me when they needed it. I find it incredibly rewarding to break down harder concepts that people often find 'scary' into more manageable steps. For example, I previously tutored a friend in GCSE Maths who was consistently stuck on a grade 4-5. By focusing on consistently appearing topics that could also appear in larger mark questions, like SURDs and completing the square, I helped her build the confidence to tackle the higher-tier papers. I'm proud to say she went on to achieve a Grade 7 in her final exams. Additionally, I regularly help my younger sister with her primary school work, helping me to develop the patience and adaptability skills needed to explain the same concept in multiple different ways and examples until it clicks and sticks to the student being taught.

Tutoring Approach:
Growing up, I've always been a visual learner; I understand that textbooks aren't always enough. I've used this to my advantage to turn it into my greatest teaching strength: I use my iPad to make every session interactive.I do this by breaking down complex topics with live diagrams, graphs, and real-life examples to break down exactly how a concept works. I also use the 'I do, we do, you do' approach to help build a genuine understanding of the topic. First, I model exactly how to tackle a high-mark exam question. Next, we collaborate on a second question and work through the steps required together. Finally, I let the student take the lead on their own, allowing them to apply their new skills with their own knowledge.
