Better do it this week then, I am not sure if you will like the normal class, it is slow too, I think. Which Harry's did your friend go to? By the way, Burwood normal class is packed! Acceleration class is not. But if you love maths, you will love Harry. He goes in-depth, VERY in-depth. The topics covered by the normal class is not hard. This week they start integration then they do area and volume of integration which is very fun if you love mathematics!
