Hi Hurley97,I am also planning on pursuing a JD/MBA. Right now I am studying for the GMAT (which will be in about 3 weeks for me). Here are some of the differences between the 2 tests:1) The LSAT is a paper test, the GMAT is all computerized. On the GMAT you have 3 sections: two scored 30 min essays, a 75 minute 37 question quantitative section, and a 75 minute 41 question verbal section. There are two 5 minute breaks.2) The two exams only have 2 parts and are similar, both have reading comp and logical reasoning questions. Although I have to tell you that the reading comp and LR on the GMAT is much easier than on the LSAT.3) You are allowed to have scratch paper for the GMAT (6 pieces to be exact), they will collect it from you at the end of the exam. LSAT does not allow any scratch paper.4) Since the LSAT is a paper test, you don't necessarily have to do them in order. You can skip ones that are tough and then go back to them if you have time. On the GMAT there is no skipping allowed. You MUST answer the question to move forward and you CANNOT go back to check or change answers.5) The GMAT is adaptive to your skill level. Basically this is how it works. The first question is a medium level question and you start off with an initial score of 500. If you get it right, your score goes up to lets say 550 and you get a harder question. If you get the first question wrong, your score goes down to maybe 460 and you get an easier question (I'm not sure of the actual fluctuations in score, but this is happening in the background). The test continues on like this, adapting to the way you answer the questions. Since hard questions are worth more points, its in your best interest to get to the tough questions as early in the test as you can, and make sure you get them right. The beginning of the test is the most important for your score.6) The math on the GMAT is high school level (but the hard questions involve many steps, so its easier to make a mistake).7) On the LSAT you have to wait 3 weeks for your score, on the GMAT you get your score right after you finish the exam. I've been studying on my own for both exams. For the LSAT I practiced on 10 more actual office lsat preptests, and I read Mastering the LSAT by Jeff Kolby. I looked over the LGB and LRB and they looked pretty good too. As for the GMAT, I would recommend going to their web site first, www.mba.com, and downloand the prep software, they have a bunch of actual GMAT questions and explanations and you can take 2 full length tests.
