Pre Algebra Test Review

I have trouble with school?
Well, last year, so I had a bad math teacher actually. She never explains anything right, leaving to most of us no idea. The only reason anyone happened was because she came back to us until we test and "understands the issues." Yes clear. So now I'm in Pre-AP Math, which is Algebra 1. It is the third day of school and we have a review Rational Numbers. I'm doing spreadsheet now, and there are lots of types of problems that we never found out last year, and do not understand. What should I do?!
