Keith Combined Science Tutors and Keith Combined Science Tuition

Personal Description:
I am a qualified teacher with over twelve years' classroom experience and a four-year integrated Master's degree in Chemistry (MSci) from Imperial College London, where I graduated with First Class Honours in 2013.

I have taught Chemistry at a leading independent boys' school, and before that spent two and a half years at an independent girls' school. I hold both Qualified Teacher Status (QTS) and a Postgraduate Certificate in Education (PGCE), and taught across a range of state schools while training. Alongside my main degree I also studied Physics and Mathematics, so I am comfortable supporting students where the three subjects overlap.

I am also the author of two published GCSE Chemistry revision guides and I have developed two companion revision apps on the App Store covering the same specifications. Both came directly out of the classroom - the points students reliably get stuck on, and the exam technique that moves grades - and my students work from the same material and the same approach in their lessons.

My aim is to help students reach their ambitions and their true potential. I encourage them to develop intellectual curiosity beyond the confines of the syllabus, and to strive for excellence in whichever field they choose to pursue. I also believe in a balanced approach, in which academic study, physical health and proper time to consolidate learning can comfortably co-exist.

Subjects and levels:

- A Level Chemistry - OCR A, OCR B (Salters), Edexcel and AQA
- Cambridge International A Level Chemistry and IB Chemistry
- GCSE and IGCSE Chemistry - AQA and Edexcel
- Mathematics - up to and including GCSE and IGCSE
- Biology - up to and including GCSE
- Younger year groups from Year 6 and Year 7 upwards

Teaching Experience:
- Over twelve years' classroom experience as a qualified Chemistry teacher (QTS and PGCE)
- Taught Chemistry at a leading independent boys' school, and previously for two and a half years at an independent girls' school
- Taught across a range of state schools during teacher training

Tutoring experience:

- Over 12,000 hours of tutoring, one-to-one and in groups
- Author of two GCSE Chemistry revision guides
- Developer of two GCSE Chemistry revision apps on the App Store (for AQA and Edexcel)
- I run the Head Start to A Level Chemistry course at Imperial College London, for students who have completed Year 12 and are moving into Year 13
- Previous experience with Kumon Maths and English
- I help organise the International Mathematics Competition (IMC)

Tutoring Approach:
How I teach:

I introduce new material by building on what a student already knows, so each concept connects to something familiar rather than arriving out of nowhere. Chemistry becomes very difficult when it is learned as disconnected rules, and much more manageable when students see how the ideas fit together.

When a student is stuck on an exam question, I don't hand them the answer. I give a hint - enough to get their thinking moving, and no more - and let them arrive at it themselves. It takes a little longer, but it is the difference between a student who can answer that question and one who can answer the questions they haven't seen yet.

How lessons run:

- One hour on Zoom, with live annotation so we work through problems together on screen
- Built around your child's exact specification - wording, mark schemes and examiner expectations, not generic Chemistry
- A shared Google Drive folder for every student, holding their resources, homework and a dated record of everything covered in each lesson, so students can revisit any topic and parents can see exactly what has been taught
- OneNote available if a student prefers it
- Small group lessons also available

PhD thesis title:

"Fibre optic sensors based on fluorescence lifetime techniques for temperature and strain measurement"

Thesis submitted for examination for the degree of
Doctor of Philosophy
at
City University
School of Engineering

November 2002

Abstract

The author presents a thesis based upon the use of the fluorescent properties of rare earth doped materials. The thesis commences with a review of the current fibre sensor technology in the field, with special emphasis on those sensors designed for temperature and strain measurement. The use of the physical phenomena of fluorescence produced from rare earth doped optical fibre for temperature measurement is then introduced and explained in more detail, particularly with regard to utilisation of the fluorescence lifetime technique in such sensing, which is then compared to the other fluorescence-based methods for measuring temperature.

The recently discovered small strain sensitivity of the fluorescence lifetime is then introduced as a theoretical candidate for potential application to simultaneous temperature-strain sensing, using two different doped fibres in a single sensing element, and subsequently state-of-the-art temperature-strain discrimination techniques are then explored for the purposes of exploitation to dual measurement.

Results achieved from using the fluorescent lifetime approach for a range of rare earth materials are then presented, followed by further results obtained from combining the lifetime technique with Fibre Bragg gratings (FBGs) for the first time. Also, the irreversible effects upon FBG performance after exposure to long-term high temperatures are explored.

Finally, there is a summary of the work presented in this thesis and the author's opinions on achievements made. Current trends in fluorescence lifetime-based sensing are discussed, both commercially and academically, together with projected work for the future.

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.

Personal Description:
Hello students, my name is Pankaj. I have done my MSC Aerospace engineering persuing my Msc aerospace engineering from uni of salford after my btech in mechanical. My dissertation was in flight dynamics and control where application of core concepts of physics and mathematics were necessary. So i sounds quite experience in application of physics and mathematics and familiar but dont worry i teach by keeping my lectures free from complexibilty. Basically I use pen and paper to teach student I write each and everything whatever I taught and gives the opportunity to student to solve problem under my guidance where I correct the mistakes via questions answer method. So don't worry definitely we will get your desire score in finals.

Teaching Experience:
Well i have five years teaching experience so i know how to use words and pen to make the more thing more comprehensive. I have been teaching complete physics and mathametics (calculus,trigo,matrix,determinant,inverse trigo) upto A levels.
I think with me you will learn more quickly and know how to apply these stuff in reality

Tutoring Approach:
I am passionate about teaching Physics and Mathematics and have experience teaching students at senior secondary level. My approach is to build a strong understanding of fundamental concepts before progressing to problem-solving and exam-style questions. I adapt my teaching to each student's individual needs and encourage them to ask questions and develop confidence. I aim to make challenging concepts clear by using simple explanations, practical examples and step-by-step methods.

Personal Description:
I'm a high-achieving graduate with a strong background in technology, passionate about both learning and teaching. With over 9 years of tutoring experience, I've helped students excel across a wide range of subjects, from Primary Arithmetic and English, through GCSE and A-Level courses, all the way to Undergraduate studies. My extensive knowledge spans core academics, arts, sciences, languages, and admissions preparation, allowing me to tailor lessons that meet each student's unique needs and goals.

I truly enjoy making complex topics accessible and inspiring a love of learning in every student I work with. Technology plays a big role in how I approach education, allowing me to create engaging, tailored lessons that spark curiosity and build confidence. By creating a supportive and engaging environment, I encourage students to overcome challenges, develop critical thinking skills and realise their full potential at every stage of their academic journey.

Teaching Experience:
I have over 9 years of tutoring experience, primarily working online but also providing private in-home tutoring. During my academic years, I volunteered as a mentor and tutor for younger students, which laid a strong foundation for my teaching approach. I have supported students across all age groups from primary and secondary levels to A-Level and university and I'm actively expanding my work with undergraduate learners.

My tutoring has helped many students achieve significant improvements, including successfully gaining admission to private schools through the 11+ exam, and boosting GCSE grades by an average of 4 grades above expectations within six months.

I cover a broad range of topics and themes across multiple subjects and educational stages, tailored to the specific needs of each student. For primary and secondary levels, I teach core subjects including Arithmetic, English, Science, Geography, History, Religious Education, Spanish, and Computing. At GCSE and IGCSE levels, I cover subjects such as Maths, English Language and Literature, Combined and Triple Science (Biology, Chemistry, Physics), Business Studies, Computer Science, Art and Design, Geography, History, Media Studies, Film Studies, Food Preparation and Nutrition, Religious Studies, Spanish, and Accounting.

For A-Level students, I provide tutoring in subjects including Film Studies, Health and Social Care, ICT and Information Technology, Journalism, Media Studies, Modern Languages (Spanish), Technology and Design, and Travel and Tourism. At the undergraduate level, I support academic writing, cinematics, media studies, research methods, and Spanish.

Regarding exam boards, I am familiar with major UK boards such as AQA, Edexcel, OCR, Cambridge IGCSE, and others, enabling me to tailor preparation to the specific syllabus and exam requirements. I also support students preparing for admissions tests such as 11+, 13+, SAT, and UCAS applications, along with TEFL exam preparation.

If there are specific papers or units you need support with, I can provide targeted lessons aligned with those assessments to ensure confidence and success.

Tutoring Approach:
My approach to tutoring is student-focused, flexible, and results-oriented. I understand that each learner is unique, so I tailor my teaching to suit individual goals, learning styles, and confidence levels. Whether students need help mastering core concepts, preparing for exams, or improving academic performance, I adapt my methods to best support their progress. I focus not only on exam success but also on building confidence, curiosity, and critical thinking skills. I hold a TEFL qualification, which complements my ability to support language learners effectively.

I incorporate a mix of interactive techniques, including technology-based tools, active questioning, step-by-step support and guided practice, and real-world applications to make learning both engaging and effective. I aim not just to improve grades, but to nurture curiosity, independent thinking, and a genuine love for learning. With over 9 years of tutoring experience, I know how powerful encouragement and personalised teaching can be in helping students overcome challenges and reach their full potential.

Personal Description:
Hi, I'm Tom. I'm 25 and have been a professional software developer for 2 years, having finished my undergraduate degree in physics and computer science at Edinburgh in 2023. Since then I've been working full time and have just finished a masters level apprenticeship alongside my work. I used to do tutoring before and at the beginning of uni and really enjoyed it so am looking to get back into it! I've also got a DBS check (issued November 2025) and would be happy to show this if requested.

Teaching Experience:
Aside from my experience at school and uni, I've got experience in tutoring KS3 and GCSE maths, science and Spanish. Whilst at school I tutored one boy from year 8 to GCSE maths, science and Spanish and whilst at university tutored another in GCSE maths science and geography. Both of these were pupils were tutored using a combination of in person and online sessions. I also used to volunteer to do reading lessons at a local primary school and worked part time at young engineers whilst at university, teaching children from 3 to 11 years old the basics of science through lego

Tutoring Approach:
I've found in the past that the best approach to tutoring is to be very positive and flexible. I have never been a super forceful or strict tutor and think that trying to be too overbearing, particularly in sessions outside of or extra to school like tutoring, just makes people perform worse. I will always try and be positive and make sure sessions are not painful for students (as I remember how much doing homework can be a chore!), but equally make sure students are getting the most out of sessions by asking questions of them to demonstrate their knowledge and checking they're confident with what we've done.
