some thoughts:

* vishugogo's advice about the CR problems is good. in fact, he has most likely understated the proportion of "strengthen"/"weaken"/"evaluate"/"explain the discrepancy" among the CR problems; together, those are probably a solid 80% of the problems.

all four of these tasks demand the same general mentality... namely, the following three points:

1/ you have to read for the main issue when you're reading through the passage -- even if there are a lot of words, there should ultimately be one main issue that you're interested in resolving.

2/ the answer choices are NOT going to be "in scope" -- i.e., the correct answer will not involve concepts that are already contained in the passage. (you can't "strengthen" or "weaken" or "evaluate" or "explain" anything if you're just rehashing concepts that have already been brought up -- the only way to do any of those things is to introduce new information into the picture.)

3/ most importantly, you are going to need real-world common sense to connect the answer choices to the issue in the passage.
if you are thinking of these passages as "logically rigorous" or "academic", then you aren't going to be able to solve any of the problems!
as just two illustrations -- in og13 cr #94, you need the common-sense fact (not spelled out in the passage) that tall buildings are normally built in city centers, where land is expensive. in og13 cr #110, you need the common-sense fact that people will be less likely to break the law if they know there's a significant risk that they'll be caught.

more generally -- don't forget that CR is specifically designed NOT to require extensive studying. It's a test of normal human reasoning processes that have already existed in your head for many years and that you use every day of your life.

this is a really important realization: you don't have to learn anything for CR. you just have to take existing thought processes, and use them with a little more care and precision than you would in a casual environment.
i.e., there are no specific "rules" that you can memorize; there are just general mentalities / ways of thinking about the situations. beyond that, you have to trust yourself!

as far as math goes --
the most important thing on the math section, by a mile, is the use of backup strategies:
* "plugging in your own values" for undetermined quantities (multiple choice questions)
* working backward from answer choices (multiple choice questions)
* estimating answers (multiple choice questions)
* testing cases (data sufficiency questions)

if you are not currently making extensive use of these strategies, then those are probably the only thing standing between you and the score that you want.
used liberally, these strategies can solve over half of all the problems on the entire math section! just think about that for a second -- think about how much more important they are than, say, combinatorics (which accounts for what, maybe 3% of the problems).

good luck.
