About Me

I completed my MSc Mathematics degree in 2020 and then worked as a maths teacher in a secondary school teaching both GCSE maths, A-Level maths and further maths for one year. Currently, I am working full time as a maths tutor. I like running, reading, basketball and meditation.

Tutor Experience

I started tutoring in 2016, I have been tutoring for 6 years.
I helped many students achieve a top grade in their studies. I teach mathematics for all different levels, GCSE, A-Level, IB, Undergraduate and Postgraduate.
I achieved a distinction in MSc Mathematics, a First Class Honours in BSc Mathematics at King's College London and A*s in both Maths and Further Maths at A-level.
To improve my teaching quality and make sure I am fully conversant with the curriculum, I spend one year in 2021 to complete the teacher training course and successfully obtain the QTS.

Yi takes a very precise and methodical approach to tutoring and offers plenty of opportunities for the student to form their own analyses. Yi started the lesson by presenting key terms to determine the familiarity of the student and how to further pitch the lesson. I liked how he clarified each of the definitions through concise examples done with the student, rather than giving prolonged explanations. In his learning checks, Yi asked not only for the answer but also an explanation from the student as to how they came to certain conclusions. Yi really challenges their understanding and has them think in a step-by-step way. I felt that the pace of the learning was steady and progressive - Yi incorporated more abstract mathematical proofs as the level of the student became more apparent. Yi’s clear and broken-down explanations demonstrate his great subject knowledge and ability as a tutor.
