I just took the test and got a 730! This is significantly higher than my practice exams - so for those of you who feel like your score is not improving, there is hope! Just try your best to relax the day before and of course the day of the test.
Here are my scores:
CAT 1: 620
CAT 2: 550
CAT 3: 590
CAT 4: 630
CAT 5: 690
CAT 6: 620
MBA.com practice exam: 660
Actual: 730
THANK YOU Manhattan GMAT for all of the help and support! :P
