I guess you must have a classmate who also needs help with the same things. I suggest you set up an IM conversation with him so you can both work on the problem together! It is the best way to learn!


p.s. If you hadn't realised I am being sarcastic, Doubling the thread won't make people help you any faster, Neither will creating multiple accounts. If this is untrue I apologise, But I suspect it is true.
