Below is a series of links for a variety of resources that you may find helpful, including GMAT forums, official GMAC Resources, books that I recommend, admissions consultants who I have worked with, and even some fellow tutors who I would recommend if I am not the right fit for you or if I am too booked up to take on new clients.
This is a great resource for information on the GMAT and business school admissions. There are prospective GMATers and applicants as well as GMAT professionals and admissions consultants.
Another great resource for GMAT and b-school admissions. The site also sells access to practice tests that I occasionally use with my students and that a fellow GMAT tutor colleague of mine really favors.
This is ManhattanGMAT’s forum so you will tend to get their bias or the bias of their instructors, but the forum has explanations to most of the questions from the GMATPrep exams so it is a good resource for that among other things.
This is the main site of GMAC, the company that makes the GMAT. This site is catered a little more to the institutions that accept the GMAT, but there is a lot of information on the site about the GMAT itself and about business school admissions.
This is the official GMAT site. You will need to come here to register for the test and there are many GMAT related resources (some of which are specifically referenced below).
This is the main page where you can access all of the official GMAC study materials, including the old Paper Tests, the new Integrated Reasoning Prep Tool, the GMATFocus Exams, and the free GMATPrep software. Note that the some of the resources, including the books, can be purchased more cheaply from other sources, such as Amazon.
This is a feature, new as of January 2015, that allows you to get more feedback about your actual GMAT exam, including time spent and percent correct on different question types.
Why, you might ask, would I offer links to other tutors and admissions consultants? Well, first of all I don’t do admissions consulting since that is not my area of expertise. As for the tutors, I have been doing GMAT tutoring for over 10 years and during that time I have gotten to know some of my fellow GMAT tutors out there. Sometimes I am too busy to take on new clients and refer students to them and other times they refer people to me. I trust and recommend each of the following GMAT/Admissions professionals.
Charles used to be a fellow NYC GMAT tutor (which is how I know him), but he moved to Denver recently. He is a master of the GMAT and super nice guy. In addition to doing online GMAT tutoring he also does admissions consulting.
Carol is an admissions consultant focusing specifically on MBA admissions. She has worked with many of the students I have tutored and has had great success getting them into top schools.
Alice, David, and the team take a very hands-on approach with their clients and, more so than other consultants, focus a lot on understanding the applicant’s profile before starting to work on the essays.
Hillary came to me referred by another admissions consultant (always a good sign) and has successfully guided some of my students not only for mba programs but also PhD programs.
Susan is an admissions consultant with many years of experience helping mba hopefuls gain admission to top business schools. She has particular expertise working with international applicants and has worked with students from all over the world.
Located in India, Kim and Kavita specialize in business school admissions consulting for international students looking to study in the U.S. They deal with many local students in India but also work online with clients from all over the world.
What follows is certainly not a complete list of the books that I use or would recommend to others (I draw upon a wide variety of resources and the specific books that I choose to use depend on the particular needs of each student), but below are some of the books that I use with my clients and/or recommend to those who are self-studying.
This is essentially the GMAT Bible. It is a must have and is the main source of practice questions for anyone taking the GMAT.
Additional Quantitative questions in case you burn through all of the ones in the main Official Guide. You don’t need to purchase this when you start but you will probably end up needing it if you do any serious GMAT prep.
Just as above, additional Verbal questions in case you burn through all of the ones in the main Official Guide. Likewise, you don’t need to purchase this up front but you may end up needing it (though perhaps less so than the Quant one).
This is a kind of hidden gem in my opinion. Not many people use it and few tutors seem to recommend it, but its a great resource that essentially gives you better, more strategic explanations to the Quant questions in the OG (the OG explanations tend to be very formulaic and really don’t do justice to the creative ways that you can solve many of the problems). The book referenced is for the OG 13th ed., but the questions in the 2015 edition are exactly the same (including the question #’s). Also, just note that you can also use the MGMAT Navigator, which is more expensive but which provides online explanations (including some via video) to the OG questions.
This is one of the books that I use with my students when they are very weak on the Math content and need a pretty basic primer. In my opinion it is a great book because it doesn’t go overboard and try to cover every minute detail, but the coverage is pretty comprehensive (for the content only) and there are A LOT of questions that they give you to reinforce the techniques. So for someone in the 400’s or 500’s its a great book to help build content mastery.
This book is indeed for test takers who are already at a pretty high level. But for those who can handle it, the book really breaks down the problem solving process and gets at how to be strategic on Quant questions better than any other GMAT book on the market. I have had a lot of success with my students using this book (that is, the students for whom this book was appropriate…it is not for everyone and I only use it in certain circumstances).
Some of my tutor colleagues are more keen on using LSAT questions than I am. That is not why I recommend this book (though it could also be used for the questions it provides). The real value, in my opinion, is that the book contains a short primer on Logical Reasoning (the LSAT’s version of Critical Reasoning) that I think is the best foundational treatment on the structure of arguments and the methods needed to approach the questions. Just note that some of the information is particular to the LSAT (Logical Reasoning question types that don’t really appear on the GMAT).
