Going for it tomorrow morning (edit: 750!!!!)

Can't give too many tips on verbal because it more or less just comes naturally to me (I didn't study at all). But I will say three things:

1) In RC and CR they give a lot of teaser choices that are very tempting to use. For instance, an RC question will ask "Which of the following can you infer to be true based on this passage?". Some of the choices they give be undoubtedly true, much more so than probably the correct answer, but if that choice is not explicitly referred to in the text then it is unlikely to be the right answer. They try to trick you with these "obvious" answers that are really not covered in the passage. Watch out for those tempting traps. Of course, topics that aren't covered in the passage can be the correct response to questions like "Which of the following, if true, would best support/weaken the author's hypothesis?".

2) I find it very helpful to read the question first in CR questions before reading the passage. This helps me go through the text with a critical eye for exactly what it is I need to get out of it. It helps you wade through the BS of the passage.

3) In SC, if you have to guess and you can narrow down to 2-3 choices, generally choose the simplest of all the answers.

4) Edited extra tip: Don't use the verbal section of this forum too much for SC! I would go through it from time to time and found many of the SC questions to be very inferior and many of the OAs to be quite debatable. Stick to reputable texts, like the OG and, apparently, MGMAT SC. SC questions are all about experience, and seeing poor questions can really screw you up.
