Lol, problem is, we don't get every sheet, just the ones which we go through in coming lesson. Plus we don't get too many of the revision tests printed out, nor any answers for the general sheets. Also, my class plods along and I'm sitting there going 'Darn, wish I had a textbook on me. :mad1:'
So $80 well spent for me considering its a subject I really wanna nail. But I've heard the Physics Prelim content ain't so relevant in HSC as, say, Math or English Prelim, where its all just cumulative knowledge and skills. So if there are better uses for my cash, jus' say.
edit: Also I'll add that the sheets from the Surfing book are clear as crystal to me...haven't seen any other Physics texts but Surfing's really effective IMO
