Hi enigma1504,
First off, a 660/Q49 is a solid Score, so it could be enough to get you into your first-choice School. As such, a retest might not be necessary. Depending on the Schools that you plan to apply to, you would likely find it beneficial to speak with an Admissions Expert about your overall profile. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Your 4 Official Scores show that you essentially performed the same each time (about 650 +/- a few points). You handle certain aspects of the GMAT consistently well, but you also make certain consistent mistakes. Since you've been performing at this level for over 4 months, it's likely that you have developed some 'bad habits' during your studies that are keeping you from scoring higher, so beyond learning new Tactics, you have to work to replace those 'bad habits' with new 'good habits.'
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). Since you purchased the ESR, I'll be happy to analyze it for you. Before you can include attachments to your posts/PMs on GMATClub, you need to have at least 5 posts in the forums. If you would rather not go through those extra steps right now, then you can feel free to email me your ESR directly (at
[email protected])
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied in total?
2) What study materials have you used so far?
3) On what 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)?
Goals:
4) What is your overall goal score?
5) What Schools are you planning to apply to and what are the exact application deadlines for each?
GMAT assassins aren't born, they're made,
