Drop in my actual GMAT score..

Hi ankschow,

Since you took your most recent GMAT on February 18th, there's no way to retake the Test before the application deadline for Rotman (on February 27th), so the immediate question is whether you're comfortable applying to that School with a 650 or not. As it stands, a 650/Q49 is absolutely in the 'acceptable range' of scores for that School, so you shouldn't hold back because of that GMAT score.

Based on what you've described in your last post, there are a few things worth noting:
1) Retaking a CAT that you've already taken is NOT realistic (as you'll almost certainly see 'repeat' questions that you've already faced) and the score result is almost always 'inflated.' Thus, we can't consider that score to be truly accurate.
2) Taking a CAT the day before your Official GMAT was NOT a good idea. The process of taking (and reviewing) a CAT requires a significant amount of energy and effort - and takes time to 'recover' from. This is one of the reasons why you typically shouldn't take more than 1 CAT per week and your last CAT should be about 1 week before your Official GMAT. If you took the FULL CAT (with the Essay and IR sections), then you likely experienced some 'burnout' on Test Day. If you didn't take the FULL CAT, then you took a shorter, easier Exam - so the score result was likely 'inflated.'
3) If you truly won't be satisfied unless you score 700+, then you're going to have to put in the necessary additional time and effort to get to that level. Considering the deadlines that you're named, you will need more time than you have to lock in that score.
