Hey Guys! I'm looking for advice.

Here's a little background: I began my studies in July (initial PT 143) and have been studying full time (9-4) since. My score has gone up to a 159 (BR 164) (I took this test about a week ago) but I took two PT's after that and scored a 151(BR 157) & 152 (BR 159). I have NO IDEA why I am regressing.

My LG score is now at a -1/-5 depending on if I can finish the game set BR -0. BUT I CAN NOT SEEM TO INCREASE MY LR or RC score ): I BR after LR, but somehow i'm stuck at -7/-8 per section (BR is sometimes the same score sometimes it's -2). And my RC fluctuates vastly as well, but normally I only get about 14 correct. ): At this point I have no idea what to do. I feel so defeated after studying for five months and not even being able to reach 160's yet. So what would you guys do in this position?
