we have a real good maths teacha who has marked theHSC for like the last 100 years (ok, so maybe a little exaggerated!!) but he's a real good teacha cuz his classes always go HEAPS well (like band 5 or 6) in the HSC and he told us the secret is PRACTICE PAPERS, PRACTICE PAPERS, PRACTICE PAPERS!! If you can, this late, get a copy, or like borrow, that copy of the practice papers...our skool was selling them 4 like $15 and they have heapsa practice papers with all worked out ansa's, including last yrs HSC exam + ansa's and specimen paper + ansa's. I have worked thru this, then any probs- i go ova the exercise in the textbook, then if im still confused (which is alot!!) i go see my teacha. Bt seriously, practice papers ARE the way to go cuz you get an idea of the level of Q's that will be in the HSC, familiarise with formal and alo of Q's are similar to those of prac papers, so i really think this is the bestest (and easiest) way to study 4 maths!!
