Going to A2Z was definitely a great investment on my behalf and I cannot imagine going through the stress of HSC without Khanh’s guidance. The classes were small which made questioning and interaction between the tutor and class mates less awkward and super useful and since he knows our capabilities, he tailors challenging problems to individually improve us and gives us pep talks when needed. What I found most useful were the extra lessons to go through HSC practice paper questions and the FREE “Homework Help” classes, available throughout the year. I am so happy to have been tutored by Khanh and would hands down recommend students to join 🙂
