Placement test preparation
I have a placement test for my community college. I was taking the practice placement test, and is very simple. Almost, offending to other people (I think). But I got a very low score on the practice test, and I'm afraid I might get placed into remedial classes which I get no credit for and have to pay.

Therefore what is the best way to study the following?
 Numerical Skills/Prealgebra Operations with Integers Multiples and factors of integers Operations with Fractions Operations with Decimals Conversions between fractions and decimals Exponents, square roots, scientific notation Ratios and proportions Percentages Averages (Means, Medians, and Modes) Percent Word Problems Number Word Problems Algebra Substituting Values into Algebraic Expressions Setting Up Equations for Given Situations Basic Operations with Polynomials Factoring Polynomials The AC method of factoring Linear Equations in One Variable Exponents and Radicals Simplifying Rational Expressions Adding and Subtracting Rational Expressions Multiplying and Dividing Rational Expressions Linear Equations in Two Variables College Algebra I Functions Exponents and Radicals Complex Numbers Other topics may include: Arithmetic and Geometric Sequences and Series Matrices (basic operations, equations, and determinants) Factorials Geometry Geometry Review #1 Geometry Review #2 Geometry Review #3 Geometry Review #4 Geometry Review #5 Trigonometry Trigonometric functions and identities Right-triangle trigonometry Trigonometric equations and inequalities Graphs of trigonometric functions Special angles (multiples of 30 and 45 degrees)

I'm thinking about reading some reviews they gave me, from purple math (which I don't always clearly understanding), watching videos on Khan Academy, and asking questions on this forum. But, I don't know if 5-10 questions on the same topic per day might annoy people. Then again I believe it might help me more to annoy you guys with 5-10 topics per day, rather than play Playstation 3 and flight simulator everyday (for those who like video games).

I usually have problems with topics like the following:

1) Simplify.
3xz + (5x + 3z)(7x – 2xz + y – 4z)

2)
Which value of
x, if any, makes the following expression undefined?

3)
 Solve the inequality and graph on a number line 7x + 4 ≤ x – 2
