Lend me your Intelligence.

As everyone knows, SPM draws near day by day. My brethren and I are struggling through extreme and rough trainings to survive the examination that will encounters us at this November. There is one problem, we don't have enough resources to learn from. We need sources for subjects such as Alchemy, Physics, Accountings, Mathematics , Additional Math and Arabics. So please, share us your knowledge or web links and you shall be rewarded by the hereafter. Thank You...
