ACCUPLACER College-Level Test Help...

I'll be taking the math portion of the ACCUPLACER test on Tuesday. There are three portions of the math test: basic arithmetic, elementary algebra, and college-level math.

For the first two portions, I can ace those easily. But when I get to the college-level math, it's extremely confusing to me.

Here is a PDF (that contains sample questions for the test) that I've been working on: http://professionals.collegeboard.co...r-students.pdf

Questions 1-10 of the "College-Level Mathematics Test" portion is the area that gets me.

For problem 1, I figured I could just subtract the exponents, which would result in 2/2, which then results in 1, so there is virtually no exponents. So, the problem would look like 2-2, which would equal 0, but that isn't a choice. I'm pretty sure I'm doing something wrong somewhere...

For problems 2-5, I just have no idea of what to do.

For problem 6, I feel as if there isn't enough information in the problem to figure out the answer. It wants to know how many two-bedroom apartments there were. I don't see how someone could find that out...

For problems 7-10, I just have no idea of what to do.

I kinda feel like a retard... I learned this stuff in Advanced Math and I already forgot it :(.
