Last Friday, I attended the biannual GMAC Summit, a special conference that the makers of the GMAT put on for test prep companies. I want to share various tidbits that you should know!

Integrated Reasoning (IR) has existed long enough now that GMAC is starting to be able to draw some conclusions about the efficacy of the section. Dr. Lawrence Rudner, chief psychometrician of GMAC, is quite pleased with the section’s performance to date.

Though they still need to collect more data to be sure, early results indicate that IR is actually a little bit better of a predictor of grades in business school than are the quant and verbal scores. It will still be a while before they can collect as solid / extensive data as they have for quant and verbal, but perhaps it will be the case that, eventually, IR will become the most important section! (Don’t worry: if you are applying right now, nothing has changed. Even if you aren’t planning to apply until next year, it’s unlikely that the importance of IR will change extensively by then.)

There were no admissions officers in attendance, but we did hear from GMAC that they have heard that admissions consultants are starting to consider using IR as a tiebreak for borderline cases. For example, let’s say a school considers 680+ a strong score and 630 to 670 an average score. For the pool of 630 to 670 candidates (only a few of whom are likely to be admitted), one potential tiebreak is the IR score.

If IR is not your thing, don’t worry: it’s unlikely that any school is making this tiebreak decision based solely on the IR score. After all, many different variables go into an application; they might also decide to use number of years of work experience, under-represented industries, or some other factor. If you do tend to perform well on IR, though, then bonus: that’s an extra mark in the plus column for you.

Interestingly, US students are tending to do a bit better on IR than all other students. (This is also true for the Verbal section of the test, while non-US students tend to do better than US students on the quant section of the test.) A lot of people consider IR more of a quant section, but verbal is just as important. If quant is your strength, then you’ll feel that IR is testing verbal more, and vice versa.

Scoring and Timing

I have only one piece of info for you here, but it’s quite an important piece of data. As we were discussing the scoring algorithm, someone asked the age-old question: whether certain questions were “worth more” than others. Dr. Rudner indicated (as he always has in the past) that the earlier questions are not worth more than the later ones. He did, though, indicate something that we suspected but had never heard officially confirmed: “outlier” questions ultimately count less towards your score.

What’s an outlier? Briefly, an outlier is a question for which your performance was unexpected. Read on to understand what this means.

An outlier is always relative to your own performance. (Note: we’re also talking only about the questions that count towards your score; the experimentals don’t matter here.) Most of the questions you answer will be within a certain range of difficulty. As a general rule, you’ll answer more of the easier questions in your range correctly and you’ll answer more of the harder questions incorrectly. This is the expected behavior.

We are very excited to announce that our new book, The Official Guide Companion for Sentence Correction, will hit bookshelve today, December 3^rd!

What is the OGSC (for short)?

It’s one of the best GMAT study guides you could have (if we do say so ourselves)!

Here’s the deal: nearly everyone studies from The Official Guide for GMATÒ Review, 13^th Edition (or OG13). This book contains about 900 real GMAT questions that appeared on the exam in the past. OG13 does contain explanations, but those explanations are “textbook” explanations: reading them is like reading a grammar book. The answers are completely accurate but a bit hard to follow if you’re not a grammar teacher (and some of them are hard to follow even when you are a grammar teacher… ahem).

So we decided to remedy that problem by writing our own explanations for every single one of the 159 Sentence Correction problems contained in OG13. We’ll tell you the SC Process for getting through any SC question efficiently and effectively. We’ll also discuss how to eliminate each wrong answer in terms that are easy for students (not just teachers) to understand. The book includes an extra section on sentence structure and a glossary of common grammar terms. Finally, you’ll gain access to our online GMAT Navigator program which lets you track your OG work, time yourself, and view your performance data so that you can better determine your strengths and weaknesses.

Who should use the OGSC?

Are you struggling to improve your SC performance? Do you love studying official problems but hate trying to decipher the sometimes-mystifying official explanations? Do you want to throw your OG13 across the room when you read yet another explanation that says an answer choice is “wordy” or “awkward”?

If something is “awkward,” there is a real reason why—and we explain that specific reason to you so that you can start to pick out similar faulty constructions on other problems in future. (Did you know that, most of the time, “wordy” and “awkward” are code words for an ambiguous or illogical meaning? The OGSC will help you learn how to decipher these for yourself!)

How can I get the most out of the OGSC?

First, read the introduction chapter, where you’ll learn all about how to work through an SC problem in an efficient manner.

Next, if you have already started studying Sentence Correction problems from the OG, begin with the problems that you’ve tried recently. Try to articulate to yourself why each of the four wrong answers is wrong. Try to find all of the errors in each answer (though, on the real test, just one error is enough to eliminate an answer!).

Note: You don’t need to use grammar terminology when you’re trying to articulate why something’s wrong, but do try to go beyond “this one sounds bad.” That’s a good starting point but which part, specifically, sounds bad? What sounds so bad about that part?

Then, check yourself against the explanations. If you didn’t spot a particular error, go back to the problem and ask yourself what clues (in the form of differences in the answer choices) will alert you the next time this particular topic is being tested. If you didn’t know how to handle the issue but now understand from the explanation, make yourself a flashcard to help you remember whatever that is for future. If the explanation seems like Greek to you, then maybe this particular issue is too hard and your take-away is to skip something like this in future and make a guess!

When you’re ready to try new OG problems, make sure to do them under timed conditions (try to average about 1 minute 20 seconds on SC). When you’re done, check the answer. If you guessed, go ahead straight to the explanation. If you got it right, try to articulate why each incorrect answer is wrong, then check the explanation. If you got it wrong, look at the problem again to see whether you might have made a careless mistake. Then go to the explanation.

Where can I get the OGSC?

You can find The Official Guide Companion for Sentence Correction on our website starting today!

Below is an excerpt from Andrew Yang‘s new book, Smart People Should Build Things: How to Restore Our Culture of Achievement, Build a Path for Entrepreneurs, and Create New Jobs in America, which comes out in February 2014. Andrew was named Managing Director of Manhattan GMAT in 2006, Chief Executive Officer in 2007, and President in 2010. He left Manhattan GMAT in 2010 to start Venture for America, where he now serves as Founder and CEO. 

Smart People Should Build Things. 

I believe there’s a basic solution to our country’s economic and social problems. We need to get our smart people building things (again). They’re not really doing it right now. They’d like to. But they’re being led down certain paths during and after college and told not to worry, they can figure it out later.

Take me, for instance. I wasn’t very enterprising when I graduated from Brown in 1996. I had a general desire to be smart, accomplished, and successful—whatever that meant. So I went to law school and became a corporate attorney in New York. I figured out I was in the wrong place after a number of months working at the law firm. I left in less than a year and cofounded a dot-com company, Stargiving, which helped raise money for celebrity-affiliated nonprofits. It was extraordinarily difficult. My company failed spectacularly, but I recovered. I went to work for a mobile software company, Crisp Wireless, and then a health care software company, MMF Systems, over the next five years, eventually becoming the CEO of a test-prep company, Manhattan GMAT, in 2006.

I spent five years running Manhattan GMAT, helping young people get into business school. I taught our corporate classes of investment banking analysts and consultants at Goldman Sachs, McKinsey and Company, JPMorgan Chase, Morgan Stanley, and Deloitte, as well as hundreds of individual students over the years. Some were exactly where they wanted to be. But there seemed to be just as many top-notch young people who wondered why they didn’t like their jobs more. They sought a higher sense of engagement with their work and their careers. Sometimes they would put words to what they were looking for; they’d say they wanted “something entrepreneurial” or “to be really excited about something.”
