Hi tuttifrutti453,
To start, your 700/Q45 is a fantastic Score (it's just a bit shy of the 90th percentile), so you could comfortably apply to just about any Schools that interest you. As such, a retest might not be necessary. You would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/If you are certain that you want to rest, then here are some ideas to keep in mind. As a general rule, "review" 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'). If you were not completing a Mistake Tracker/
Error Log after taking each CAT - and not focusing on learning and practicing the Tactics that you were presented, then that would help to explain why you have not hit your Score Goal yet.
The GMAT is a remarkably consistent and predictable Exam, but it does not sound as if you were properly focused on taking advantage of those consistencies. To hit your Score Goal, you cannot afford to 'wing it' through the Verbal section. Everything that you'll see in the Verbal section is predictable - the tricky part about the Verbal overall is that Verbal questions do not have a 'safety net' - meaning that if you make a little mistake on a Verbal question, you won't realize it (you'll just convince yourself that one of the wrong answers is correct). Thus, you really have to train to spot (and take advantage of) all of the patterns that appear in the Verbal section and you have to get good at taking consistent, organized notes. The Quant section of the GMAT is NOT a 'math test' - it's a 'critical thinking test' that requires lots of little calculations as you work through it. To score at a much higher level in this section, you need to become more of a 'strategist' and less of a 'mathematician.'
All things considered, you're actually closer to a 730+ than you probably realize - and you could potentially retest in 1-2 months and hit your Score Goal. To reiterate the prior point though - regardless of which study materials you use, you have to be focused on making the necessary changes to how you "see" (and respond to) the Exam.
GMAT assassins aren't born, they're made,
