haha bio is too easy, i did it for yr11, got like 84% for doing very little and then dropped it, its not stimulating enough for me. There is a bit of overlap with chem, so i guess it wasnt a total waste. i came 4th/about 60 in the school, and did close to nothing (additional work at home, ie homework), thats because all idoits that pick a science go for bio. Also i was getting kind of sick of all the blonde questions people asked, its all common sense people!. if u dnt understand it go smoke another bong!
