I have been studying for 4-6 hours a day for the past three weeks and 6 hours a day for the past week. So far I have linear and advanced linear games down via LGB and pretests 29-38. I can consitently do 5 games with -2 or less untimed. I study by doing a game, correcting it, and writing out explanations for all answer choices. (Already read applicable LGB chapters.) I am currently doing grouping games,I am not sure how well I'm improving. Some days I can do 4 games with -2 or less in one day. Some days I can miss as many as 3 on each game. There is no real pattern on the types of games I am missing. Does this mean I'm making small mistakes and missing inferences?
I didn't take a diagnostic before I started studying, so I decided to take one this morning.
The Results:
PT 33
Section 1 LR (-17)
Section 2 RC (-12)
Section 3 LR (-16)
Section 4 LG (-14) Raw 42 Score 142
I want to take the June test. My goal score is 160. I have never in my life studied for anything this hard and failed. I feel terrible.

I think it will be much easier to improve my RC and LR score once I learn the LGs. From your own personal expierence, what am I doing wrong?
