"After having math lessons with Mr. Lei in term 3, I have experienced a significant improvement in both understanding and exam results. I gained a better understanding on topics such as trigonometry and polynomials through his clear explanations and evaluative feedback on my homework and past papers. Mr. Lei also adapted to my needs in explaining topics ahead of school, which helped me tremendously during math classes. My improvement in the subject has been reflected in my grades, where I improved from failing term 2's extension 1 paper to getting 86% in term 3's exam. His knowledge and explanations will definitely benefit any student."
