The best tools is definitely the Original Guide by GMAC, together with the two practice tests. These questions were written by those who write the questions you’ll see test day. Manhattan GMAT is also very helpful, esp. from the standpoint of walking you through concepts–from basic to advanced.
I have just signed up for Magoosh. Really enjoying the practice question and lessons.
I am finding the verbal really tough. So thinking about joining Full courses. I am really confused between Veritas Prep And Manhattan GMAT. What would you recommend.
Can you please provide some insight?
Manhattan GMAT is by far and away the best – I completed the 9-week course in February, and just took the test this past week. I'm proud to report that I scored a 760 on my first try. Manhattan GMAT definitely gave me the tools necessary to achieve such a high score. The instructors are excellent, and the supplementary materials are top-notch as well. Included with the course you get their entire set of review books (8 total), the 3 published Official Guides, access to 6 online practice tests, extra question banks with practice problems, and a 30-minute private tutor session each week, among other things. Unlike other test prep companies I have used in the past (for other tests, not the GMATs), Manhattan GMAT seems to genuinely care how each of its students do.
I have friends who have used some of the other prep programs (Kaplan and Veritas), and they were not as pleased with the course, nor did they do as well on the test. Manhattan GMAT has the reputation for being the best, and I really do believe that it must be true. I would recommend the course to anyone (whether you are a weaker student or a stronger student) looking to improve your score.
