Subjects

Personal Description:
I am a computer science graduate and have over 10 experience working within the IT sector as a programmer, Systems Analyst, Business Analyst, Database Developer and then as an IT consultant. Having worked in at least 6 different companies including the NHS, I currently work with a major Bank as a Business/Systems Analyst and Data Architect. As an Analyst and Architect, I am very methodical and logical in my thinking, which always helps when breaking down a problem to people (students) new to the concept. I am currently also studying for my MSc in Data Science.

I'm a very friendly and caring person and have lots of experience of working and interacting with young people in an educational context. I am forward thinking and very creative in finding better ways to explain new concepts to students.

I have experience of working with 1st year to MSc IT students. This usually involves tutoring around concepts not well understood, tutoring to help you start/progress/complete complex assignment and dissertation/thesis.

Teaching Experience:
I have tutored many students ranging from 1st Year to Masters students over the past 8 years leading to usually very positive outcomes. Over this time I have supported students on 3 undergraduate dissertations, 2 masters thesis and on numerous assignments and IT Topics.

Tutoring Approach:
I am very flexible and ready to adapt to make sure that each student gets the most of any teaching session. I understand the fact that each student is different with different pace of learning and understanding. It is with this that I take my time to understand the student in order to optimize the learning experience. I do encourage feedback from my students to make sure that they are happy with the learning.
I am flexible with the teaching session location and I do own my own transport. Also I am flexible as I can do online teaching. Using school text books or lecture notes/slides is my preferred approach as this does not conflict with anything that has already been taught to the student in school or university.

Personal Description:
I am 54 years old, I am married with four children. I have a degree ( Joint Honours, 2.1 in Agriculture with Agricultural Economics) and a Cert Ed. I am a member of the Institute for Learning. I have taught a wide range of subjects over 28 years and am able to coach you to success whether you are looking for science, geography, Excel spreadsheets, English as a Foreign Language or even French and German ( I worked in both countries when I was younger)

Teaching Experience:
I can help you prepare for exams in Geography, Biology, Ecology, French and German. I have taught English as a Foreign Language over many years. I can also help you with Microsoft Excel spreadsheets, particularly for Business. I am a patient, enthusiastic and committed teacher with 28 years experience particularly with post 16 and adult education. I have taught agriculture and related topics over that time, and very much enjoyed diversifying my teaching portfolio as new courses arose at the college. I have taught a range of biology and geography related topics, including plant and soil science, crop science, crop production, livestock production, environmental issues, ecology, woodland management. In business I have helped many people develop diverse enterprises, preparing carefully costed cash flow projections. I very much enjoy seeing people develop confidence with Microsoft Excel spreadsheets, which are an invaluable tool.

Tutoring Approach:
I am convinced that one-to-one tuition is by far the most efficient way in which a person can progress and gain confidence. Often someone can grasp a topic in 5 minutes of one-to-one that would have taken 2 hours to cover with a larger group. Once you are confident with a topic, we move on rapidly to the next one. A current A level tutee of mine told his father "I learnt more in that 2 hour session than I have all term at school" and his headteacher wrote to congratulate him on his improved grades. (The reason for this is not that his teacher is bad, far from it, but a tutor can give you personal one-to-one attention, concentrating on the bits you need) I always ensure that the learners are confident with each step before progressing further.

Testimonials

I am currently studying A level French and I am very pleased to be able to say that my French has improved more than I ever thought it would since starting tuition with Michel. In just over one month, I have improved by two whole grades, which has been evident from mock exam results in class at school. I thoroughly enjoy my lessons with Michel because I do not feel embarrassed to ask seemingly simple questions, which I feel I cannot ask in my class at school.
E. H. - Bromley

My daughter who is doing A level French was really struggling before we found Michel. He has really motivated her and has made lessons more interesting . She has 2 hour lessons but she is surprised how quick the time goes. I would highly recommend Michel. I can see he gets pleasure helping his pupils make progress. My daughter`s accent has also greatly improved with Michel`s help.
Mrs G - Croydon

I`ve just received my results and I`m very happy to tell you that I got an A for my French I-GCSE. Thank you for all your help because it really made a difference! - G - Bromley

Hi Michel,
Thank you for your help. I got A* in my French oral! - C. Sevenoaks School

I just wanted to say thank you so much for all the sessions, they really helped me get a high grade for speaking and an overall A. Thank you so much - S - Orpington

I have enjoyed Michel`s teaching immensely. I would very much recommend Michel to other students- he`s really quite adaptable and has used some creative approaches to teaching which was really helpful for me.

Subjects

Personal Description:
I am a mechanical engineer with MPhil in Engineering for Sustainable Development from University of Cambridge.

Teaching Experience:
I was involved in conducting the training camp for the selection of the team that represented Pakistan in the 36th International Physics Olympiad, held in Spain. I was involved in conducting exams, practicals, marking, teaching as well as coordinating tutorials sessions with professors.

Tutoring Approach:
I like to take a practical approach to teaching. I want to give an intuitive feel to the students to help him grasp complex concepts. I do this by giving everyday examples to highlight the subjects under study. I want to
make science fun, cool and intuitive for students and remove the myth and misconceived perception that it is difficult and boring. If the teaching approach is correct, there is no reason why students will not be thrilled by laws and mechanisms of universe.

Subjects

Personal Description:
I have over 15 years of teaching and tutoring experience in both university modules and A-levels for all major exam boards, specializing in computer science, programming, mathematics, and economics. This extensive experience includes both in-person and online teaching, encompassing one-on-one tutoring as well as small group sessions.

Throughout my career, I have maintained high success rates, and tutoring is my passion. My teaching approach is individualized, as I believe every student has a unique learning style. I adapt my methods to ensure the learning process is efficient and engaging for each student. Many of my students have secured places at Oxbridge and other top universities in the UK.

Over the years, I have accumulated and developed a substantial collection of learning materials and exercises in the aforementioned subjects. I share these resources with my students to help them master the material and excel in their exams. Many of these materials and exercises have been custom-developed by me to provide individualized support whenever the available textbooks and standard exercises are insufficient. Additionally, I regularly administer written tests to identify gaps and areas for improvement, which also help students prepare more effectively for their exams.

As a tutor, I am motivated, friendly, patient, and open-minded. My strong communication, problem-solving, and analytical skills allow me to connect with my students and help them overcome challenges. My lessons are organized in a friendly and relaxed atmosphere. Instead of simply reiterating textbook content or going over available exercises, I focus on explaining and emphasizing core concepts, identifying any gaps or misconceptions the student may have. I create an interactive environment where students can develop their critical thinking and problem-solving abilities. Furthermore, I teach my students strategies for solving problems quickly, which is crucial in time-constrained exams. I also guide them in selecting the most appropriate methods and techniques for different problems, enabling them to perform well by quickly addressing the core of each problem without wasting time on less effective approaches.

Overall, my approach to working with a student is as follows: First, I consider the specifications provided by the exam board for the specific subject or module. Next, I discuss with the students/parents to identify any special needs, requirements, and preferences that need to be taken into account. Together, we develop a suitable teaching plan and identify appropriate teaching and learning resources. This teaching plan typically includes regular homework exercises for the student to study independently between tutoring sessions, reinforcing the knowledge and skills acquired during our time together. This approach makes the tutoring sessions much more effective, allowing us to focus specifically on the student's needs rather than spending time on concepts they can understand independently through textbooks or worked examples. I always aim to provide the best value for money, ensuring that even a limited or infrequent number of sessions can significantly improve the student's understanding of the subject and their performance in exams. However, I also ensure availability for as many sessions as needed, with many students opting for several sessions per week or even daily sessions when exam dates are approaching.

Teaching Experience:
My educational background includes undergraduate and PhD degrees in Computer Engineering from the University of Patras (Greece). I have worked as a postdoctoral researcher at prestigious universities such as Cambridge, Surrey, and Essex. Additionally, I hold a teaching qualification for Higher Education from the University of York. I have also taught undergraduate and postgraduate modules at the Universities of York, Warwick, and London in the aforementioned areas.

I have over ten years of experience working on industry- and government-funded R&D projects related to next-generation computing and Internet technologies, cybersecurity, and artificial intelligence. This experience has provided me with invaluable insights into advanced computing systems and electronics, novel techniques for computer networking and communications, as well as practical skills and knowledge in protecting systems and networks from cybersecurity threats. Furthermore, I have acquired strong programming skills across a wide range of programming languages and mathematical modeling techniques.

Tutoring Approach:
Currently, in addition to tutoring A-level and university students, I also deliver specialized training programs and masterclasses to professionals in organizations worldwide. I assist university graduates in preparing for industry-required professional certificates. Additionally, I provide consultancy services to both start-ups and established companies within my areas of expertise.

Feel free to reach out to me to discuss your requirements. I am eager to help and support students in achieving their goals. Before booking any lessons via the system, please make sure to contact me first, as my availability shown on the system may not always be up to date.

Personal Description:
My name is Leon and I provide tuition for maths and computer science to make these subjects easier to understand and fun to learn.

Using my experience in teaching and commercial application of these subjects, I am able to provide a thorough perspective that extends beyond the limitations of traditional classroom lessons. By presenting context for how maths and computer science concepts are used in the real world, I am able to make these subjects easier to understand with a complete explanation for how they are used to solve problems that everyone can relate to.

Self belief is the biggest obstacle preventing people from achieving their full potential. By using my learning techniques and support, I can help you to overcome difficulties created by learning anxiety, dyslexia and dyscalculia that lead to your potential being underestimated. By deconstructing the unnecessary jargon and written notation behind maths and computing, I help students to exceed expectations and achieve the highest grades in as little as 12 weeks.

Teaching Experience:
I have taught maths and computing as a professional tutor and commercial trainer for over 10 years. My lessons can also be tailored to cover exam preparation for all major exam boards, including AQA, CEA, Edexcel, OCR and WJEC.

The following are the subject levels that I have experience of teaching:

Maths:
- Key Stage 3
- GCSE
- Functional Skills

Computer Science:
- Key Stage 3
- GCSE
- A-Level
- Degree
- Master's degree.

Tutoring Approach:
Whatever your reasons for considering tuition, my lessons can be custom designed to extend your potential to achieve the highest grade possible. Whether you're already a high performer or you find maths / computing a challenge to understand, my custom lesson plans allow you to learn at a pace that suits your individual requirements.

By avoiding the use of technical jargon and complicated notation, my lessons present concepts in a format that's easy to understand and practise. Each lesson is designed for you to achieve the following learning objectives:

- Understand a specific concept.
- Perform the concept.
- Write the concept as maths notation or programming code.
- Develop exam technique.

Using custom digital learning tools, you will be exposed to a hands on approach to learning the concepts behind maths and computing. My lessons begin with a visual presentation explaining the focus topic, followed by interactive exercises that help you to experiment, express and reinforce your understanding. With my support and collaboration, each exercise challenges you to describe and refine your thinking process to solve a puzzle using the skills taught in the presentation.

Once you are confident in your ability, the lesson progresses to applying your understanding of the concepts to creating and understanding written notation and code. This stage of the lesson prepares you with the ability to work with exam questions and other assessments that you are preparing for.

The most important component of effective tuition is your ability to practise between lessons. To help you gain the most benefit from my tuition, the digital learning exercises are made available to you as a practise tool between lessons. My learning tools also allow you to receive feedback on your practise throughout the week or during the next lesson.

STUDENT FEEDBACK

"Umer explains things in a clear and concise manner and has made learning Physics ever so fun for me. He is punctual and continuously tailors his teaching style to suit the needs of the student he is teaching." - Kalpna, A2 Mathematics

"More often that not, students spend a considerable time studying unimportant things. Umer has the ability to channel the effort of his students in the right direction, resulting in effective exam preparation. If it wasn't for him, my son wouldn't have scored so well in his exams." - Carlos, A2 Mathematics, A2 Physics

"Umer often uses visual aids to explain abstract concepts. He takes time to understand the interests of his tutees and then uses something of their interest to explain complex phenomenon to them. This really keeps the child motivated and involved. Hats off to his teaching style." - Roma, AS Physics

"Umer has tutored me from grade 8 through to A level. He is knowledgeable, reliable, patient and always polite. He constantly maintains a positive approach and encourages me even when I perform badly. He also helps me organise my study schedule and remained a great source of motivation for me. I would blindly recommend him to anyone!". - Basa, Mathematics (grade 8, GCSE, AS, A2)

Tutoring Approach:
- The underlying factor for my success is my ability to change my style of teaching according to each student's ability

- I provide practical and lively examples to explain concepts in Maths, Physics and Chemistry

- I guide my students towards obtaining correct answers with a series of well-placed questions rather than providing them with information to `rote learn`

- Tipping exam questions is a common practice and I can do this nearer to exam period

- I am very patient and endeavour to remove the abstraction in mathematical concepts through simplification of seemingly complex procedures

- I am a strong believer in building a good relationship with my students

- I tend to focus on harder exam questions early on so that students are not overwhelmed with them nearer to exam time

- Providing students with visual representations in science works wonders in establishing their concepts

- Asking students to teach back what I taught them some weeks ago also helps in improving their communications skills besides serving as a revision tool

- Providing students a clear mental image of the process being taught when teaching sciences. For instance, explaining the concept of electric current by modelling it as a flow of water
