For critical reasoning.

for sentence correction

MANHATTAN GMAT SENTENCE CORRECTION BIBLE
for reading comp
1000 reading comp document
only practice the stuff for gmat ...the LSAT is useless
look at the answer choices ....see why you got the answer wrong and examine all the wrong choices
verbal ---tricky b/c
1) tricky answer choices
2) need to practice to see the traps
3) hard reading comp with lots of vocab
remember for reading comp, you're not suppose to understand specific science passages, you just need to understand the primary scope of the passage. don't get bogged down with hard words.
Also, the first 10 verbal questions are crucial. I had the first 10 correct and the rest I just kinda didn't do as well, but still pulled off a 38 on Verbal. A friend of mine got a couple of first 10 questions wrong on Verbal and got the same amount of answer wrong compared to me but only scored a 28 verbal. So, that just shows how important it is not to screw up in the first 10 questions.
This is only stuff I'm using and I scored a 38-42 on GMAT PREP verbal. I will tell u if I do well on the real gmat.
Best of luck on future preparation.
