lol, sounds like a wild waste of time. these people are going to be grossly unprepared for uni when they aren't spoonfed everything. less is more imo - you don't need tutoring to do well, particularly group tutoring. The main value imo is asking questions when you get stuck. A good teacher is sufficient. If they aren't good, then yeah, maybe private tutoring. But I never really got the appeal of large group classes. Sure they have good resources, but this is the HSC, you can find tons of free stuff online.
