I'm on the same boat as you. Except i got like 20% on chemistry for the trials.. DAMN. Its my worst subject and i've tried understanding it but its way to complicated for me to handle. Like i get the theory, but the calculations are the worst, but whats gonna make me fail even more is that i haven't written any lab reports to revise before my exam. well i'm hoping i get a high marks on all my other subjects. which is highly unlikely ^__^ SHT
