GMAT Strategy

Once you find out the score you need, how you do on one diagnostic test (if not a few) and how you need to present your best self in your applications...you will do the math and figure out if you need to take a course, find a tutor, study buddy or not.

The fact that you're disciplined would indicate to me that considering working with a tutor who will focus in on bolstering your weak areas might wind up being much more cost effective, and have more ROI, than a course - - you'll be saving a lot of class time. Though hourly, for the expertise and product of one-on-one attention, you'll likely be paying more. Again, going to business school is an investment in your future...and I hope you don't want to scrimp on your education or chances of getting into the best school.

Again, this also all depends on where your score winds up being and what kind of student you are.

I also recommend you take a diagnostic test from the GMAC folks themselves. There are 4 free ones available online..and numerous retired tests for sale. I believe getting questions straight from the 'horses hooves' is going to offer the least biased score. I recommend these tests before going over to 3rd party tests, though if you're going to use 3rd party tests, embed them in your study - - do them in the middle and begin and end with the real thing.
