It was quite a while ago that I took it. I also didn't need to get such a great math score since I was going into a social science program. Math isn't my strong suit either. I remember buying two books, one that gave examples of how to work on different types of questions and another that had a lot of practice exams. I took all the exams, timing them. Studying like that seemed to help. My scores on the practice exams went up as I took more of them.

Wishing you the best!
