Gmat Algorithm

Question

I am seriously confused on how the GMAT algorithm is actually working. In one of my official exams, i have gotten a Q84 with 4 scattered mistakes where i got my second question wrong and gmat being adaptive gave a Q84. Whereas in another attempt i got a Q81 with 4 wrong questions at the end, (18-21). I need help understanding this algorithm in order for me to work on in the future.

Hi. The placement of the mistake does not matter as much on the GMAT Focus. It is has a minor effect really, so the placement of the questions does not matter. What matters are the parameters each question carries and how they impact the algorithm. More here: https://gmatclub.com/blog/gmat-algorithm-explained/

Hi   Missb19  ,

In general, getting multiple questions wrong in a row will have a larger impact on your score than if the mistakes are scattered. On the other hand, it's mostly a myth that early questions on a section are "worth more" than later questions.

As bb mentioned, more important are the characteristics of the individual questions. In particular, mistakes on questions classified as easy are penalized more than mistakes on questions classified as difficult. And while  in general  the better you do, the harder the questions you get, this is far from being a one-to-one correspondence.

So what does this mean for you? One of the most important implications is that you need to pace yourself so that can give every question a real shot (or at least the opportunity for a proactive guess). It looks like you had to rush the last two questions. That's not too bad (and you're obviously strong in Quant), but if you want to maximize your score, better pacing could give you those extra points.

Hope that's helpful!

The most important factor is the difficulty of the questions that you got wrong. If you get Easy/Medium questions wrong (whether in the beginning or later), the score will tumble. Mistakes in a sequence one after the other lead to higher penalty. So pace yourself appropriately, use the Review and Edit option smartly (discussed here: https://anaprep.com/purpose-of-review-a ... n-on-gmat/ ) and review all these questions in which you took 3 or more mins. There is some conceptual gap to fix in those topics. GMAT Quant questions typically take 1-2 mins only.
