Question 302837
Michelle, please take heed of this advice.
1. Don't use your full name on any public websites including this one, first names OK, but not full names, it's not safe. 
2. Waiting until the last minute to learn a whole bunch of stuff makes it very difficult for you to learn concepts especially over the internet. 
Here's a better way: Read your book, check your notes, go through problems that your teacher solved. Read the book again and then do problem after problem.

I'm not trying to come down on you but you're putting the tutors and yourself in a bad spot. You're setting yourself up to fail. As you read through the book, problems, and notes and an issue comes up that you don't understand, then post a problem and someone will help. This is the best way for you to learn the material. Posting a general HELP won't get much help coming your way. Good luck!
