How do I learn if I don't already

[setite]

I am 26, almost 1.5 successful semesters into CC. I took the ACT when I was trying to get into UNLV, to make up for my high school GPA from 2004 being just under the 3.0. I sort of glossed over the math portion because I don't remember most of it. I didn't realize that I would have to take two remedial math courses before I got to take the math I want. Since that is too many semesters in limbo I need to take the College Mathematics CLEP.

My question is how would I go about "learning" this stuff since I seem to be drawing a blank on all of it. I have gone through part of the IC for it and I have the REA book, but neither seems to be much in the way of actually teaching me. I would like to avoid getting a tutor, but I need a system that actually teaches me these things.

EDIT: To clarify, REA and IC seem to be nothing more than practice quizzes. I was quite disappointed to see less in the way of instruction on IC. Also I have used the search function, but ALEKS was confusing as I couldn't seem to find out what I needed. If someone has used ALEKS, can you say what section is related, because there was nothing sounding anything like College Algebra.

Lastsly I even emailed the ALEKS people and never received a response. Also, I am not a dull person, but I have ADHD and math is something I have difficulty with. I get A's in my CSN classes, I have a few Bs on classes where I simply forgot an assignment or two that ruined my grade. So I just need a little extra explanation. I'm doing okay on individual flash cards by googling for explanations but I don't feel like I'm retaining much.
