Hi alexlat11,
Many Test Takers are unhappy with their initial practice scores, but you really shouldn't be. That 410 is just a measure of your skills right now - and you'll improve on that result over time as you learn more about the content, Tactics and little 'secrets' of the Exam. In addition, many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so you might not necessarily "need" 7.5 months of study time to hit your Score Goal (although it's great that you have given yourself that much "lead time" for the task at hand!). Raising a 410 to the point that you can consistently score 700+ will be a challenging task - but the GMAT is a remarkably consistent, predictable Exam, so you CAN train to score at a higher level.
Based on the information that you have provided, I have a few questions about your timeline going forward:
1) When will you be finished with your Undergraduate studies?
2) Over the next 7 months, do you plan to be working (re: full-time job, internship, etc.)?
In addition, rReview" is an exceptionally important part of the GMAT training process; your ability to define WHY you're getting questions wrong is essential to defining the areas that you need to work on (and the specific things that you need to 'fix'). As such, I'd like to know a bit more about your last CAT. While a full Mistake Tracker would provide a lot more information, there are some basic questions that you should be able to answer (and the more EXACT you can be with your answers, the better):
After reviewing each section of this recent CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
5) How many Verbal questions did you 'narrow down to 2 choices' but still get wrong?
GMAT assassins aren't born, they're made,
