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.
