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 and Science, 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 International Baccalaureate 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. 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.
