Very informative. Thank you, i-think-so. I hope to score in the range of 760 to 800. That's what I hope, whether I will be able to achieve that is... well... I hope I will. As for the schools, there is only one school I would really like to go to and that is NYU Stern. HBS, Kellog, Wharton, etc. they all offer great MBA programs, but Stern is the one I would like to attend. I see that you too have listed all three official GMAT guides as a must. Many others seem to agree with you. Kaplan 800 also seems to be highly recommended. The questions there are said to be much harder than actual GMAT, so if you have reached an advanced level, so to speak, then that guide is the one to tackle. Once you are done with that satisfactorily, you can handle anythig GMAT throws at you. I considered Manhattan GMAT's books, but there were not enough reviews for me to base my decision on. So, I omitted that. But I will consider your recommendation of its Sentence Correction guide. So, are you a prospective MBA student, current MBA student, MBA? If you are, I would certainly appreciate hearing more about your experience. Thanks.
