My GMAT test is two weeks away. I've been studying hard for over two months, but I'm not really seeing any improvement in scores over that time period. I'm consistently in the 500-540 range and my goal is 600 for the schools I'm looking to attend. Quant is definitely my weakness, but my Verbal scores are not great either.

Aside from the GMAT, I think I have a solid application. My GPA in college was a 3.8 from a large, well respected university (majored in business, with a concentration in marketing). I have 5 years work experience, will have good references, no gaps in jobs, I think I interview well, have extracurricular activities, volunteer, etc.

At this point I'm really disheartened that I haven't seen much improvement in my practice test scores and I'm not even close to my goal. Should I take the test as scheduled in hopes that even a bad score will get me accepted if I apply early (my top choices for schools have rolling admissions)? OR should I cancel my test, keep studying, and take again in a month or so thereby delaying my application with the potential of risk of not even improving my score? OR should I just scrap the whole business school idea since I'm apparently not cut out for it (according to the GMAT)? I'm planning on attending B-school part-time while still working full-time (or maybe a little less than full-time), if that matters.

Ugh...
