I got a 36Q on my first practice test, and a 44Q on the second. On the first test, I really tried to solve every problem, and ended up not finishing. On the second test, I analyzed each question quickly, to determine whether I knew how to solve it. If I was stumped, I quickly guessed and moved on, without putting much effort into it. I totally guessed on the last 5 or 6 questions, as I had less than 2 minutes left at that point. I didn't feel good at all about my performance, so was surprised at the 44 score. (I had also started getting easier questions toward the end, not a good sign!) But what I learned from this is how very important it is to finish the test! I'm sure I missed more of the ones I answered on the second test than the first, but got a much better score. Bottom line for me, don't be afraid to guess and move on.
