Sounds like the school isn't being very helpful You could maybe try looking in the yellowpages for a tutor or tutoring program. Math is one of those things that its really really helpful to have someone sit with you one-to-one to go through.

You could try looking for online help too, something like typing "algebra tutor" into google may find you some useful resources. I found this link that way ... http://www.algebratutor.org/

One last thought is to maybe try talking to someone in one of those educational stores, like a Scholar's Choice or Learning World or something - they may have some suggestions or referrals, or they may be able to give you some more ideas to try.
