OG 13 accuracy

by housecat » Sun Jun 24, 2012 4:16 pm
Hello All,

I am wondering if I can get some data on how the accuracy levels in OG 13 (using the OG 13 error log) translate to real GMAT scores.

Currently I am hovering about 80-85% in most sections and yet to take GMAT.

That's a super hard question to answer. As far as I know, there's no easy conversion between the OG13 questions and your score.

There's also the issue of timing to consider. Getting 80-85% correct AND completing every question in under 2 minutes is different from completing them in 4 minutes.

You really need to take a practice GMAT to get an idea of where you stand.

Cheers,
Brent

Thanks for your response Brent.

I agree that practice test is a better indication of your performance, but I just wanted to get an estimate of how accurate people are while solving these, of course under timed conditions. I solve 10 questions at a time and on an average take less than 2 minutes for each question, but I make silly errors which has nothing to do with concepts.

I read somewhere that you can still get a great score (700+) with about 60-70% accuracy on the actual GMAT, wanted to get some data to decide before believing in it.

People who score 400 and people who score 700 get about the same number of questions correct (60-70% sounds about right). The only difference between these two test-takers is that the person who scored 700 correctly answered questions with a higher level of difficulty than the person who scored 400.

Agree with Brent on this and probably that's why the percentage accuracy is no indicator of the range of score that you may get in actual GMAT.

However much I wanted to know the same, the percentage accuracy is again a blend of Math & Verbal scores ( which again might be varied individually) added numerically, lack of the real exam stress & the normalization that comes with level of difficulty for the questions.

It may be possible that the you are doing good if most of your questions in the end are going right. They say that the difficulty level in general increases as you approach the end. I'm not sure how true that is , for I've felt a uniformity in the difficulty level for all questions.
