Strong starting point for quant. Verbal is more problematic, obviously.
Good analysis. So, clearly there are timing problems (as with everyone!). You need to start following the advise in this article:http://www.manhattangmat.com/blog/index ... anagement/
On DS, I think your bigger problem is that you didn't spend enough time to get things right! You were spending too much time on PS, and so you likely made mistakes that you might not have made had you not been rushing on DS.
And on PS, if you need 3.5 or 4m to get something right, I'd rather that you get it wrong in 2m. Losing 1.5 or 2m on one problem means possibly getting 3 or 4 other problems wrong, since you're likely going to try to "save" around 30s on multiple problems in order to make up the time deficit.
So, you're not okay on PS - you have a significant timing problem right now, and timing is just as important as accuracy. Don't discount it. :) It looks like you've got an idea of what content areas you need to cover for quant.
Agree on verbal - start with SC. If part of your trouble for RC and CR is reading speed and reading comprehension, then know that this can take a while to improve, and you need to do a little bit of reading from GMAT-like sources every day.
Here are some ideas:http://www.beatthegmat.com/mba/2010/09/ ... ading-comphttp://magazine.uchicago.edu/http://harvardmagazine.com/http://sciam.com/
(use the last one especially if you don't like science topics)
In one study session (defined as a 2-hour block of time), concentrate on either quant or verbal. Don't set an absolute time limit or deadline for a particular chapter or book. Do what you need to do in order to learn the material (but recognize that you will have weaknesses, and it's okay to say "I'm not going to learn this as well," as long as you're pushing yourself most of the time and not just giving up).
Start with the first few chapters of SC. Then do some quant, then go back and do some CR, then SC, then some quant again. You're obviously going to spend more time overall on verbal - plan about 2x time (or a little more) on verbal.
SC can really be done chapter by chapter - you don't have to do the whole book before you go to another verbal topic. For CR, do the intro / strategy chapters together, and then you can start going chapter-by-chapter when you get to the problem chapters. For RC, again do the intro and strategy chapters together, then do short passages, then do long passages.
I agree that you don't want to take another CAT till you've made good progress - and that's a qualitative judgment. Plan to take a good 3-4 weeks and, when you feel like you've made good progress, schedule yourself for another CAT. Don't worry about your overall score after you take it - worry about whether you got better at the specific things you were studying in the preceding 3-4 weeks.
Geo is not that commonly tested - it's the least commonly tested of the 5 quant books. Of the rest, NP is probably the most important, as well as algebra. In Word Translations, the most important areas are algebraic translations and statistics. Fraction and Percent problems are also pretty common.
If you want 700+, you pretty much have to do all of SC; the only chapter of lesser importance is the "odds and ends" chapter. But note that there are some Advanced chapters in all of the books. You don't need to do all of the Advanced material - only do the Advanced chapters for your areas of strength. Otherwise, ignore those chapters.
I don't have an Excel file for an error log, but I describe how to create your own error log here:http://www.manhattangmat.com/articles/error-log.cfm
You may also want to search online for one created by another student.
You're currently at 490 and want to hit 700+, or 210+ points. Most people would need a minimum of 3-4 months for that, though it obviously varies from person to person. May 23rd is less than 2 months from now - most people would not be able to pick up 200 points in 7 weeks.
So you probably will need more time, though there's no way to predict for sure. It sounds like you have already booked that date in May, but that's fine - just leave it and you can reschedule later on if you decide that you need more time.
Note: the GMAT is changing on 5 June: after that date, you will write only 1 essay but you will also have to take the new Integrated Reasoning section (which means you will have to study for that new section). So if you take it after that date, you will have to plan for some extra study time to study for the new section - I just want you to be aware of that.
