Going from basics to advanced?

Hello everyone, I browsed the forums a bit and tried to look around for the best place to post this, but there's no "General Math" area that I could see. If I am posting in the wrong place, however, please feel free to warn me and move the thread appropriately. Thanks.

I have a bit of a past that I'm kind of ashamed of, but nonetheless I now need help. I dropped out of high school about a week after I started, so I haven't even taken an algebra class. Ever since I was 8, I've wanted to develop games for a living. However, game development requires an extremely high level of math. For the past few years I've been studying, but without much of a routine to follow. Glancing at books here and there. I took a placement test at the college I wanted to attend and was going to be placed in "College Algebra" (the test consisted of binomial multiplication etc.). Monetary issues arose and I wasn't able to make it to college when I wanted, so I have a few months to study before I do begin. I just don't know where to start... I want to try and review the basics, then start with Algebra and move up to at least trigonometry. My problem, though, is that I'm not entirely too sure how. I have looked up several books, but I don't know which ones are the right ones to purchase. I have pretty much until August / July and don't mind doing the work necessary to get where I want to be. This includes 2 - 3 lessons a day if I'm able to.

Does anyone know of some decent books I can pick up that will give me the equivalent knowledge of someone that has gone through high school? Books, programs, even if they're kiddie books, I don't mind. I just really need help... I don't know where to start! (Angry) (Worried) (Crying)
