Hi HarmonicFury,
The answers you've provided are actually quite useful, especially since you have a stated Score Goal of 760.
To start, the 760+ score is the 99th percentile - meaning that 99% of Test Takers never score that high (regardless of how long they study or the number of times that they take the GMAT). Thankfully, NO Business School requires a score that high - so it's important to realize that the score that you "want" and the score that you "need" are not the same thing.
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, but with your current timeline, you might be trying to spend less time than that (which would likely limit how much you can improve). Since you have not taken a FULL-LENGTH CAT yet, we have no idea about your current skills, strengths and weaknesses - which means what you asked about in your first post might not actually be what you 'need' at this point. Thankfully, you're not planning to apply until Round 1 in 2019, so you have plenty of time to study and improve. You have to decide how efficient you want to be with that study time though - and many Test Takers who use a 'book heavy' study approach end up getting 'stuck' at a particular score level. Since you're planning to take that type of study approach, there's a reasonable chance that you might end up getting stuck too.
At this point, I highly recommend that you take a FULL-LENGTH practice CAT Test; you can take 2 for free at
www.mba.com (and they come with some additional practice materials). A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have that first CAT result, you should report back here and we can come up with a study plan.
GMAT assassins aren't born, they're made,
