Hi stm579,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so the fact that you scored 640 after just 1 month of inconsistent study is an encouraging sign (and shows that you are a fairly strong critical-thinker, which is great!). With a Score Goal of 730+, another 2 months of consistent, guided study will almost certainly be required (so a Test Date in April is a reasonable idea). Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
A CAT/mock is really a 'measuring device' - when used correctly, it will give you a realistic score and help define your strengths and weaknesses, but it will NOT help you to fix any of those weaknesses. To raise your scores, you have to learn the necessary Tactics and put in the proper practice and repetitions. The CAT will show you whether your studies are helping you to improve or not. In addition, the process of taking (and reviewing) a CAT requires a significant amount of energy and effort - and takes time to 'recover' from. This is one of the reasons why you typically should not take more than 1 CAT per week - and your last CAT should be taken about 1 week before Test Day. Going forward, you really should not take more than 1 FULL CAT per week.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on your timeline and your goals:
1) What were your Quant and Verbal Scaled Scores on your Official GMAT?
2) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
3) Going forward, how many hours do you think you can consistently study each week?
4) When are you planning to apply to Business School and what Schools are you planning to apply to?
From your initial post, it sounds as though you have purchased the Enhanced Score Report. While the ESR doesn’t provide a lot of information, there are usually a few data points that we can use to define what went wrong on Test Day (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you. Before you can include attachments with your posts/PMs, you need to have at least 5 posts in the forums (right now, you have 2 posts). If you would rather not go through those extra steps at this point, then you can feel free to email me directly (at
