Are you saying that you want the complete worked solution provided to you today...? There is one guy who surfs by sometimes that posts full answers that you can hand in as your own work, but I'm afraid legitimate tutors don't do this.

Or are you saying that you need links to lessons, so you can re-learn these topics (which, I gather from your comment, you've forgotten over the years) by this evening? If, so then:

I'm afraid it simply isn't reasonable to attempt to teach lessons within this environment. To re-learn these topics (if you're willing), please study from some of the many lessons available online. Use any major search engine to find what you need.
