Okay - so you're planning to take the official test in both February and March? Is there a reason why you're doing it twice? (eg, sometimes people like to have a 'dry run' first official test to help them know what to expect the second time - in particular, people who tend to have a lot of anxiety when taking standardized tests.) I just ask to make sure you actually do have a good reason for planning to take it twice, because I also know that some people get discouraged if they don't do as well as they'd like on a first test, and I don't want that to happen to you!
You mentioned that CR and DS were your strength when doing OG but were weaker on the third CAT. There are multiple reasons why this might have happened; see if any of these apply to you:
- did you do the OG questions timed?
- did you do the OG questions in random groupings (so that you had to figure out what type of question you had next, etc)?
- what were the difficulty levels of CR and DS on your test? Did you happen to get harder questions, on average, for those two areas? [I just went and looked at your original mail and saw that, for DS, your difficulty level was significantly higher - so that's part of the reason your performance wasn't as good as it was on PS! On CR, though, your difficulty level was lower, so something else is going on here.]
- how was your timing on the practice test? One thing I see a lot, for example, is that people spend too much time on one type (say PS), and that takes time away from another / the other type (eg DS), and then they perform more poorly on DS... but they only spend, say, 1:40 on average on DS, while spending 2:10 on average on PS. Well... it's not unexpected to have DS drop in these circumstances - the person isn't spending enough time on questions of that type!
- which specific types of math are you better at vs. worse at? Did you happen to have more DS test problems in your weaker areas?
- which specific types of CR questions are you better at vs. worse at? Did you happen to have more CR test problems in your weaker areas?
- were you running out of time in either section and did you happen to have more DS / CR towards the end?
So go back and figure out why your CR & DS performance dropped. If you had harder questions on average in those areas, then don't worry about it too much (DS - see above!). If you messed up the timing such that you spent significantly less time on those question types, then your focus is on improving your timing - not necessarily fixing something fundamentally wrong with CR/DS. If you happened to get more questions in your areas of weakness within CR and DS, go study those areas of weakness.
On Word problems: try this technique. Read to the first punctuation mark (period, comma, whatever), and then ask yourself: okay, what did that tell me and how should I write it on my scrap paper. Then read to the second punctuation mark and do the same thing. Repeat to the end. Don't read the whole thing first and then have to go back and figure out what it all means. Try to figure it out piece by piece as you go along. If you misinterpret or mischaracterize something, after you've realized this (which may not be until you read the explanation), go back again and figure out WHY you misinterpreted / mischaracterized it the first time, why it is supposed to be the way the explanation says it is, and how you will remember next time around to interpret / characterize it in the right way.
On RC: go back and look at why you're getting these problems wrong. Most of the time, people infer too much. The test doesn't really want you to infer the way we infer in the real world. Instead, it wants you to find the answer choice that MUST be true given the information in the passage. No assumptions, no arguments - it has to be true according to the info in the passage.
For example, if I tell you that I think cats make the best pets, you might infer in the real world that: I like animals in general; I like pets in general; I have a cat; I have other kinds of pets; I like other kinds of cats (lions, etc); if we went to a pet store and I bought a pet, that pet would be a cat; if I came over to your house and saw your cat, I would pet it and play with it; etc. But not one of those would be acceptable as a GMAT inference answer! Instead, an acceptable answer might be something like: I don't think dogs make the best pets; at least one other type of pet is better than dogs; some other types of animals besides cats can act as pets; etc.
The "real world" inferences aren't acceptable because you could argue with any one of them. I might like only cats and no other animals or pets. I might like only house cats and no other kinds of cats. I might be allergic to cats and therefore don't have a cat, wouldn't choose a cat if I were at a pet store, and wouldn't pet or play with yours. (By the way, large parts of this scenario are true! I do think cats make the best pets - at least, they'd be the best for me - and yet I am actually allergic to them.)
The "GMAT inference" examples are acceptable because you can't argue with them. If I think cats are the best, then by definition, I don't think some other type of pet is best, and any other type of pet is not as good as cats. By the same token, if I think cats are the best, then I must accept that there are other categories of pets - "best" is a comparison, so I must be comparing to other types.
You have to hold yourself to that standard on both RC inference questions and CR draw a conclusion questions. Do NOT give them a "real world" inference. Give them something that must be true according to the info already given in the passage / argument.
Re: difficulty levels, your percentile is around 60 in quant, so you can skip the first 50 problems in OG for DS and PS. For verbal, your percentile is lower, so there you shouldn't skip any. Although your quant is better than your verbal, I'd still spend your time about 50/50 on each, because it's often easier to improve your strengths. Use the results of your most recent practice test to drive what you want to review - and don't forget about timing. You may have gotten lots of some problem type or content area right, but you may have spent too much time doing so. You still need to study those areas, whatever they are, because you need to learn how to do the work more efficiently than you have been doing it!
