It's a very weird test, but I think if you keep at it you eventually recognize it's subtleties. Not to scare you or anything, but all my friends that got in did end up writing it twice at least. Usually all of them had scores near 150 their first time, then they bumped them up to the mid-160s. In my case, I think I just rushed through it too fast and didn't spend enough time per question. I was finishing the sections early by like 5 minutes because I wanted to get through all the questions. The quality/quantity trade-off is a huge element. I took a course too, but it was one of the shorter intense kinds and since I had already done my own studying some of the methods of approaching questions conflicted with my own if you know what I mean.
