There is no review or reference for Richard.
I was one of the top Mathematicians in my year and received acceptance into the first round of the British Mathematical Olympiad in 2011, this means that I was in the top 1000 Mathematicians in the UK of my age and the year above. I also received the school prize for being the best Chemistry student in Sixth Form.
Although having no formal experience as a teacher in school, I was asked by my Sixth Form Maths teacher to come in during my gap year and teach the Additional Further Maths class. I also have attained an A level in Additional Further Maths (this was not available as an option above), which I self taught and achieved a grade C in (unfortunately the last exam went badly, full results details available on request).
