Questions from Law Student

I would just jump right in with a practice test. The GMAT prep software comes with 2 tests, so take one now, then save the 2nd for after you've done studying/taking other practice tests from other places. This way you know what the test looks like right off the bat, and can get an idea where you biggest return on investment of study time is going to be. For instance, critical reasoning and reading comprehension might be easy for you since you see a lot of the same stuff on the LSAT. But sentence correction, quant problem solving, and data sufficiency might be the best place to put your time into since you only have a short amount of time... plus you can get a feeling for the timing, what the test looks like, and where you are starting. Typically we suggest 3 months to reach your full potential, so time is of the essence.

Couple points... make sure to answer ALL questions in both sections, even if you have to guess when time is running out (you get more penalized for not answering than getting a question wrong). Also, make sure to try the integrated reasoning section that comes before the real test even starts... This was just added to the test a month back...

Once you have a feeling for the test, you will have a better understanding for what the GMAT is, and where to go. Good luck

PS. If you have a deadline for when you need to take your test by, it might be smart to book your test date now so you can get the best time and day that you want.
