I agree, the MGMAT practice exams will make you want to quit, but I must say, today after a year of practice and coming from a non-traditional background (fashion design), I am making serious progress using their books, and online course. I have been going at this GMAT for over a year straight and if I score anything over 600 I will be happy. My first practice test was a 360 with Princeton Review
, and I never pasted 390 after taking the full course and 3 practice test.
With Manhattan GMAT
my practice test went from 410 - 560, and I am pushing harder to break that 600 and I plan to take the test mid or end of Oct. So dont give up on them, if I can do it, with no math or english courses in college, other than art history, you can do it.
I find it helpful to take a test, and print out all the answers to the ones you got wrong and go over them until you get it. I go over them during my commute to Manhattan.
