I have some very exciting news to announce.
For the past several months, we have engaged Dr. Lawrence Rudner, former Chief Psychometrician of the Graduate Management Admissions Council (GMAC, the makers of the GMAT®), to review our practice tests. Dr. Rudner is one of the world’s leading experts in item response theory, the testing principle on which the GMAT is based. He is the definitive authority on the GMAT examination.
And here’s what he has to say about Manhattan Prep’s practice exams:
“I conducted an extensive examination of student data for all of the Manhattan Prep test questions and I was very impressed. I can attest to the fact that very high percentages of Quant and Verbal items have excellent psychometric properties. I can further attest that Manhattan Prep’s GMAT practice exams do an excellent job of predicting a student’s score on the actual GMAT examination. Manhattan Prep’s GMAT practice exams can help you accurately gauge when you’re ready to achieve your goal score on the real test.”
In short, our tests do “an excellent job of predicting” your score on the real GMAT. That’s great news!
I am particularly excited about the fact that our CATs were so strong that Dr. Rudner offered his endorsement without requiring us to change a single thing. Going into the review, we had thought that we would be given a required list of changes before he could give his seal of approval.
I do have to add a caveat: nothing is perfect and not everyone scores on the real test exactly what they scored on our test (or any practice test). No standardized test is that precise, including the real GMAT. There are also other factors that can negatively affect certain students, such as anxiety (you know your practice tests don’t really count) or mental fatigue (don’t study for 6 hours the day before the real exam!).
Caveat over. In general, you can trust our exams to help you know when you’re ready to get in there and take the real thing. I already felt that way before, but now I can say it with conviction, because Dr. Rudner has confirmed the accuracy of our exams.
I have to give a shout-out to all of our instructors who have worked so diligently on our exams over the years—you know who you are. We literally would not be having this conversation right now if not for your hard work and dedication to making our materials the best. Thank you for your love of teaching and your complete fascination with the GMAT. I’m proud to call you colleagues and friends.
And back to our students: Go forth and study! You can beat this test!
Now that the new 2016 Official Guide books are out, I’d like to talk about how to use these problems to get the most out of your study. I also want to talk about what not to do, as a lot of people end up essentially wasting these great study problems (not to mention valuable time!).
What should I NOT do?
Your goal is to learn from the Official Guide (OG) problems in such a way that, if you see something similar on the real test, you’ll recognize what to do on that new problem.
Keep some things in mind:
- Your goal is NOT to memorize how to do the problems that you’re studying. You won’t see these exact problems on the test! Can you tell me exactly how to do a particular problem? That’s great. But I care far more whether you can tell me how you know what to do and why you want to take the steps that you take. If you can, then you’ll know how to think your way through a new problem on the real test.
- Your goal is NOT to try to get everything (or even most problems) right. Sometimes, what you want to recognize fairly quickly is that you should guess immediately and move on. Other times, you want to recognize that your best strategy is to spend some time making an educated guess—and then move on. Still other times, you’ll have to be able to recognize that you initially thought you could do this one but it’s just not happening, so you’ll need to cut yourself off, guess, and move on.
On June 24th, GMAC (the organization that makes the GMAT®) made two announcements that change the GMAT testing game. Read on to find out what they are!
Do you work for a non-profit? How about promote positive social change? Manhattan Prep is honored to offer special full tuition scholarships for up to 16 individuals per year (4 per quarter) who will be selected as part of Manhattan Prep’s Social Venture Scholars program. The SVS program provides selected scholars with free admission into one of Manhattan Prep’s Live Online Complete Courses (a $1299 value).
These competitive scholarships are offered to individuals who (1) currently work full-time in an organization that promotes positive social change, (2) plan to use their MBA to work in a public, not-for-profit, or other venture with a social-change oriented mission, and (3) demonstrate clear financial need. The Social Venture Scholars will all enroll in a special online preparation course taught by two of Manhattan Prep’s expert instructors within one year of winning the scholarship.
The deadline is fast approaching: July 6th, 2015!

I’ve just finished trying all of the new verbal OG problems. (If you haven’t yet read my earlier installments, start here.) This installment includes my summary of All Things Verbal as well as lists of the new problems by book and question type.
Also, we’re hard at work writing new solutions to add to our GMAT Navigator program, so if you have access to Navigator, you can start to check for new solutions there in—best guess—July.
What’s new in Verbal?
Now that I’ve seen everything, I’ve been able to spot some trends across all of the added and dropped questions. For example, across both The Official Guide for GMAT® Review (aka the big book) and The Official Guide for GMAT® Verbal Review (aka verbal-only or the verbal supplement), 6 science passages were added (out of 11 new passages total), while only 3 were dropped. In addition, 3 social science passages were added (compared to 5 dropped) and 2 business passages were added (compared to 2 dropped).
So, in the books at least, there’s a slight shift towards science. It’s unclear whether this signals an actual change in emphasis on the test, though; these may just be the best retired passages that they wanted to use.
For Critical Reasoning, the same total number of questions were added and dropped. The differential (added minus dropped) for Strengthen questions was +8. Further, 6 of the 22 total new Strengthen questions are fill in the blank (FitB) format, and no new FiTB’s were introduced that were not Strengthen questions.
The differential for Weaken questions was -8 and for Inference questions, it was -4. I’m not entirely sure what to make of the drop in Weaken. I’ve been hearing from students that they’ve been seeing a lot of Strengthen / Weaken on the real test and not many (CR) Inference questions. The Strengthen jump and the small Inference drop seems to go along with that, but not the larger Weaken drop. (This is why I’m always skeptical about drawing broader conclusions based on changes in the books.)
As I mentioned in my first report on Sentence Correction (part 2 of this series), it is difficult to compare categories here because one SC can (and usually does) cross multiple topics. The trends I reported before still hold after my review of the Verbal supplement: meaning and sentence structure are increasingly important, and parallelism and comparisons are just as important as they’ve always been.
Ready for the problem lists?
I have now done every last one of the new quant problems in both new books—and there are some really neat ones! I’ve also got some interesting observations for you. (If you haven’t yet read my earlier installments, start here.)
In this installment, I’ll discuss my overall conclusions for quant and I’ll also give you all of the problem numbers for the new problems in both the big OG and the smaller quant-only OG.
What’s new in Quant?
Now that I’ve seen everything, I’ve been able to spot some trends across all of the added and dropped questions. For example, across both The Official Guide for GMAT® Review (aka the big book) and The Official Guide for GMAT® Quant Review (aka quant-only or the quant supplement), Linear Equation problems dropped by a count of 13. This is the differential: new questions minus dropped questions.
That’s a pretty big number; the next closest categories, Inequalities and Rates & Work, dropped by 5 questions each. I’m not convinced that a drop of 5 is at all significant, but I decided that was a safe place to stop the “Hmm, that’s interesting!” count.
Now, a caveat: there are sometimes judgment calls to make in classifying problems. Certain problems cross multiple content areas, so we do our best to pick the topic area that is most essential in solving that problem. But that 13 still stands out.
The biggest jump came from Formulas, with 10 added questions across both sources. This category includes sequences and functions; just straight translation or linear equations would go into those respective categories, not formulas. Positive & Negative questions jumped by 7, weighted average jumped by 6, and coordinate plane jumped by 5.
Given that Linear Equations dropped and Formulas jumped, could it be the case that they are going after somewhat more complex algebra now? That’s certainly possible. I didn’t feel as though the new formula questions were super hard though. It felt more as though they were testing whether you could follow directions. If I give you a weird formula with specific definitions and instructions, can you interpret correctly and manipulate accordingly?
If you think about it, work is a lot more like this than “Oh, here are two linear equations; can you solve for x?” So it makes sense that they would want to emphasize questions of a more practical nature.
The new Official Guide books are here! Last time, we talked about the Quant portion of The Official Guide for GMAT, aka the OG or the big book. In this installment, we’ll discuss the Verbal section of the big book. Later installments will talk about the Quant Review and Verbal Review (the smaller books), as well as question lists for the new questions.
(Note: I have not yet had time to analyze the IR problems that come via your special online access. I’ll get to that soon—the quant and the verbal are higher priority!)
Part 1 included an overview of the changes to the whole book; I’ve included that overview here as well (the next section!), in case you’re reading this installment first. (The only difference is one sentence in the first paragraph.)
What’s new in OG 2016?
Approximately 25% of the questions are brand new, and there are some beauties in the mix. As I worked through the problems, I marveled anew at the skill with which the test writers can produce what I call elegant problems. On the verbal side, I loved how some of the new questions wove meaning into the issue of Sentence Correction; if you have been focusing on grammar and shortchanging meaning, you’re definitely going to need to change your approach.
