I am a PhD student studying Chemistry at Imperial College London. I like helping students understand concepts and improve their grades, which is why I signed up to be a tutor. During my A-level years, I was also selected as a Chemistry mentor to assist one of my peers. This reinforced my understanding of A-level Chemistry, and was a valuable teaching experience. It was especially rewarding to see my peer's grade improving from a D during the preliminaries to a B for A levels. I have also been tutoring A-level student throughout my undergraduate studies, and have been in charge of delivering university tutorial lessons.
