I am an LSE first year student received 3A*(including science)3A in IGCSE and A* in both A-level Mathematics and Chemistry. I have been tutoring IGCSE and A-Level maths and sciences at school for students from Year7 to 13, successfully improved my tutee's A-level math grade from F(38%) to an A(81%) in three months. I have kept my high-school notes and I'm happy to share them; also I am familiar with the specific tricks to tackle GCSE and A-level exam questions. I'm sure I can boost the student's understanding of these subjects, therefore improve his/her grades effectively.
