Need to refresh my pre calc

Tried posting in homework help but don't have privileges?*

Well until recently (6 months after graduating High school) I applied to a community college to start my way towards my career. Now next week on Wednesday I have to take a math and reading placement test. I get to choose which test, starting with Algebra I all the way to Calculus. Unfortunately for me and mistakes I made senior year I high school I can't really remember much up until some Pre Calc. I did take AP Calc for one semester, I got a D of course since I didn't really do much work or attend class. Now of course I regret some decisions I made, but I'm in need of a website/guide that includes the following topics:

* Exponents, Logarithms, and Radicals
* Functions and their Graphs
* Geometry
* Linear Equations, Linear Inequalities, Absolute Values of Linear Expressions, and their Graphs
* Polynomials, including Quadratic Equations
* Rational Expressions

I need to "re-learn" this all before Wednesday since I wish to pass the test with a good enough score to start of at least back into Pre Calc or Calc. I appreciate all help given. Thanks.

 

Here, try Khanacademy. It has a lot of information that's useful. It also has other subjects such as history and science. Though, a lot of it is math.
