Actually I finally got around to sitting down with a pen and paper and doing the Math Problem Solving (before that, I had only done reading comprehension, sentence correction, critical reasoning, and data sufficiency, the things that you obviously don't really need scratch paper for) and

I did badly. It said I was in the average range. This is not good. I had relearned all the little random math stuff like how the sides of a 30-60-90 triangle are in the ratio 1:3^1/2:2 and that combinations can be solved by n!/(k!(n-k)!) and random stuff like that... but man, when I was trying to solve the problems, I felt in over my head.

I really don't even know how to do math problems anymore

I guess this is the type of thing where it's not a matter of learning the math concepts but learning how and when to apply them... There were questions like which is closest to the product of all the prime numbers less than 20 with 10^6 10^7 10^8 10^9 10^10 And I was looking at it like what the ****? Am I supposed to solve 2*3*5*7*11*13*17*19???

I realize now that it's simple and it goes up from 2*3*5 is 30, *7 is 210, and it adds an additional digit each time but I wasn't imagining anything like that when I was trying to solve it.
