Hi cogsngears,
First off, a 700/Q49 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. 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/There's no harm in continuing to study though, but before you decide either way, it would help to know a bit more about your prior studies and current goals:
Studies:
1) How long did you study before each of your 3 Official GMATs? How many hours did you typically study each week?
2) What study materials have you used besides the Course that you mentioned?
3) What "brands" of practice CATs did you use during each phase of your studies?
Goals:
4) When are you planning to apply to Business School?
5) What Schools are you planning to apply to?
You might also choose to purchase 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 you should work on to score higher. If you purchase the ESR, then I'll be happy to analyze it for you.
