1.Anything and everything on factoring. Factoring is what makes algebra algebra.

2.Substitution of variables in systems of equations.

3.You need a general mode of attack on word problems. Something like:
a)What is given?
b)what am I supposed to find?
c)what quantity should I assign a variable to?
Factoring Factoring Factoring!

4)How to factor and solve quadratic and cubic equations.

I'm not sure how far your book goes but it is important to understand the rules of graph transformations:

f(x-a) is a slide to the right a units
f(x)+a is a slide up a units
etc...

FACTORING FACTORING FACTORING.

and if your very concerned, call the class smarty pants and see what they've done to prepare for the test.

Well, as I say, just be prepared to factor and solve some word problems. If your book covered any trig, memorize the functions.

Factoring special products:
$a^2 + 2ab + b^2 = ?$
$a^2 - 2ab + b^2 = ?$
$a^2 - b^2 = ?$
$a^3 + b^3 = ?$
$a^3 - b^3 = ?$

$y = a(x - h)^2 + k$
