>>6Don't worry too much about school. It will pass. As for joining the collage, the system is not near to flawless. IMO it is actually a joke. But since you gotta go in, talk to teachers, ask the right questions, and not "I want to know everything".
As for housework, talk to your parents about it. They will understand that school is more important!
Relationships.. Oh boy.. I wouldn't be able to give much advice on that topic... My relationships end because I get bored (yes..).
And Neku, don't worry too much! The Universe has a strange way of doing things, and if you want something, belive me, it will show up when you most need it ;P
