Over the last twenty years I have gained significant classroom and management experience at several State, Grammar and Independent Schools. I have been out of the classroom environment recently but continue to keep up to date with Education Policy and support students away from the school environment via home tutoring.

I am an experienced teacher with a passion towards my subject and have a great desire that all pupils across the ability range are inspired by Science; there is no greater job satisfaction for me than when that inspiration leads to students excelling in examinations or pursuing a career in medicine. As Head of Biology at Kingston Grammar School I managed a team of four experienced teachers- as well as being actively involved in the overall management of the Science department.

I was successful in improving both A-Level and GCSE results year on year. I was responsible for co-ordinating Community Service placements for students in the wider community. I also worked closely with Brunel University with their PGCE programme and was part of a team inspected by OFSTED and I was awarded as ‘outstanding’ in my mentoring work with PGCE students at Kingston Grammar.

Whilst my teaching specialism is Biology I have also taught Chemistry and Physics at key stage three, four and A Level. I have a broad knowledge of the science curriculum and how it fits in to schools academic policies and wider educational policies. I also have a good understanding of International Baccalaureate programs and Vocational courses. I have written schemes of work and working policies for a department as well as full risk assessments for practical work. I also have experience of intake of student new to a school be it a state school or an 11+ or Common Entrance at 13+. I have administered 11+ and 13+ examinations as well as being part of a team of interviewers assessing a student’s suitability for the school.

He believes in his students and gets things done via them, so that his students realise their potential. He knows that every student has a unique learning pattern and never backs away from giving extra time beyond the session timings to make sure the student understands the concept entirely. He strives to see the smile on his students' faces after watching them get over their weakness. He shares a great camaraderie with his students, and makes sure they are not trying to mug up the concepts rather understand them and finally derive them, which is the only way they get to know how to apply them, where to apply them.

I have over 15 years of experience tutoring Mathematics and more than 10 years teaching and tutoring Mathematics and Physics. I have taught IGCSE in the past and have extensive experience tutoring IGCSE and A-Level Mathematics and Physics, particularly with Cambridge International (CIE) and Pearson Edexcel. I help students strengthen their understanding of difficult concepts while also focusing heavily on exam technique, past-paper practice, mark schemes, and the way questions are structured. As an experienced international school teacher and examiner, I understand the importance of showing clear working and giving the precise answers examiners are looking for. I adapt my lessons to each student, whether they need help catching up, improving their grades, or preparing intensively for their final examinations.

This is Dr. Salma W, a passionate educator with a strong foundation in science and education. I hold a MA degree from Liverpool John Moores University, a PGCE certification, and a MSc degree in Clinical Pharmacy from Al-Azhar University, Egypt. As a former IGCSE student myself, I excelled in multiple A-Level subjects, including physics, achieving very good grades, which gives me a firsthand understanding of the curriculum and what it takes to succeed. With around 10 years of experience teaching science and physics across British curricula, I have spent the past 4 years specializing in A-Level physics (CIE). I focus on building students' problem-solving skills, scientific thinking, and real-world application of concepts through engaging, inquiry-based learning. Having walked the same path my students are on, I continually adapt my methods to incorporate modern educational strategies, helping them develop critical thinking and research skills to prepare them for academic and career success.

Teaching provides a unique opportunity to shape lives and influence young people towards a responsible future, hence, my passion for teaching. As one with a passion for Mathematics, Physics, Chemistry and Biology, I understand that many students face real challenges grasping the concepts of the subjects. Hence, teaching provides me the avenue to tackle this, while also making a contribution; giving back to the society and also challenging myself towards further growth and development. I have taught since my secondary school days; taking more than 800 students in total; at various levels (on a one-on-one basis, in groups and at mass teaching levels). I have also taught at various educational levels (secondary and tertiary) as well as to a diverse range of student ethnic backgrounds with a very high success rate in student comprehension evinced by their later performance. Having gained significant experience teaching this subject, I have a very broad understanding of what is expected of students writing the GCSEs and A-level exams. I have also prepared students for varying exams including the – 11+, 13+, 16+, and curricula - GCSE and A-levels (Edexcel, OCR, AQA), IB (SL and HL) and Scottish National with excellent results from students - most of my students achieving grades 8 and 9. My teaching success rate has been largely due to my deep and vast understanding of the subject matter, coupled with my calm, interesting and engaging manner of communication that makes even an average and uninterested student develop a desire for Maths and Science. I use diverse teaching-aids, web-resources etc. as necessary."

I hold a First Class honours degree in Chemical Engineering and a Masters degree in Advanced Chemical Engineering from the Imperial College of Science, Technology and Medicine. I am also a UK Qualified Teacher with more than 4000 hours teaching/tutoring experience over a period of 15+ years. This has provided me with diverse experience necessary for tutoring different students' backgrounds with evident successes in the exams. I am hoping to be of help and assistance to any student in need.
