I am currently in year 10, and I’m in the top 3 selective schools and my parents are looking for tutoring centres for physics. I’ve heard Zhangs HSC is good but I don’t know which tutors are good or not considering that I’m starting off with the preliminary course. Does Mr Zhang teach all branches or only online? And I don’t know if it’s good in terms of understanding and progress cause I have heard that it is quite fast paced. I heard cognito is more small paced and has smaller classroom sizes, and I’d say my physics knowledge is medium-high, I can adapt to fast paced but I do need some understanding. Which tutoring is best for preliminary and I guess higher studies later on?
