Stuck... in a rut precalculus

<p>I had a dismal high school life I dropped out. Moving right along I then got my GED. Now enrolled at Suffolk County Community College I've taken Algebra I and received a C. Then things got much better and I received an A in Algebra II. (for me that was huge I never though I could receive an A in math let alone any Algebra class...) then comes Pre-Calculus.. boom brick wall. Am I doing something wrong? I feel like I can follow along, but I just don't seem to reach that 'aha' moment where I get it. Is it me or the book lol... am I actually not that good at math at all.. ugh any advice would be great.. I keep trying to persevere by buying books like
E-Z</a> Precalculus (Barron's E-Z): Lawrence Leff: 9780764144653: Amazon.com: Books </p>

<p>Pre-calculus</a> Demystified 2/E: Rhonda Huettenmueller: 9780071778497: Amazon.com: Books</p>

<p>Algebra</a> & Trigonometry Problem Solver (Problem Solvers Solution Guides): Jerry R. Shipman, Algebra Study Guides: 9780878915088: Amazon.com: Books</p>

<p>and a few others but I just can't seem to get it to stick..</p>

<p>here is the general course description if it helps..

<p>and here is the textbook.
Precalculus:</a> Enhanced With Graphing Utilities: Michael Sullivan: 9780131356948: Amazon.com: Books</p>

<p>I've tried tutoring and it works when they explain it.. but I can't get comfortable practicing it on my own.. without feeling like i'm missing something.
If I can get to Calculus I feel like the door will be wide open for me. I am fighting to be a CS Major one day. (lol if I ever get past precalc I and II I guess..)
I've also tried Khan Academy, thattutorguy.com <em>shrugs</em> I'm beginning to feel defeated.
Thanks for reading</p>
