I still KNOW the quadratic equation, just not what it means

I have forgotten basically all of math, and I want to learn it again from the ground up.

While attempting to prep for the GRE, I realized that I have really lost my entire math background. I was extremely frustrated by trying to do the exercises in my GRE book, because I've forgotten even the little things from, like, 7th grade algebra that I used to take for granted I knew.
The thing is, I actually used to be pretty good at math- I did two years of AP Calculus in high school and did, well, ok at it- but I then placed out of college math with my AP scores and never did math again. Now it's been five or six years and I can't so much as add fractions or remember what the purpose of the quadratic equation is. I couldn't even remember the formula for the diameter of a circle until I looked it up, for cripe's sake.
This isn't just about prepping for the GRE. As I was struggling with my GRE book, I realized that I actually LIKED math, and I'm sad that I've forgotten it. It's like I forgot a language I used to know, or something. (I thought I didn't like it while I was in school, but that was mostly because I had an hour of math class and an hour of math homework every single day, which burned me out.)
SO. I would like to completely reboot my math knowledge, starting with the absolute most basic stuff (like, arithmetic basic) and moving up at my own pace until I can do at least basic calculus again. Ideally I would have access to LOTS of problems with available answers, so that I could spend as much time as I needed on a particular topic. I expect I'll advance through the basic stuff pretty speedily, and then take my time with the more advanced stuff.
What is the best resource or resources for this? And have any of you guys ever tried to do this before, after such a gap? How was it?
