Meh, i know my teacher didn't teach me properly, so i kinda used my brother and my textbook to do the course. The calculations were easy except for the copper sulfate one, it was tricky no? ^.^; i ended up with 0 u.u; because well, the way i saw it i was right :'( but it can't be :$ Anyways, i agree, the test was fairly easy but im afraid my answers weren't detailed enough. I mean, they could of asked a bastard question about batteries or biopolymers, blech!
