I've been scoring in the low 500's on the MGMAT practice exams. I took the GMAT today and got a 620. I must have gotten really lucky. Now I'm thinking I can improve more. I just had a few questions.
1st: Is this jump in score very rare? Have you heard of other students doing this? I thought MGMAT quant was much harder than the real thing.
2nd: If I took a live class through MGMAT would it help me raise to 670+?
