Logic games, terrible!

[tressr461]

I started the studying yesterday. I've taken 3 exams. Started at 156 and got up to 166 on the last one. The problem is that my RC and LR have gotten better quickly, -4 and -1 respectively, but I suck at logic games, -9, and I don't see it improving. These things are impossible to do in time and it's a straight up IQ test. Any tips?
