Hi all,

I recently wrote two mock tests.

1) GMAT PREP- I had 10 incorrect in quant and 20 incorrect in verbal. My score was 550. (Q47/V21)
2) Kaplan - I had 10 incorrect in quant and 17 incorrect in verbal. My score was 680. (Q48/V35)

Regards,
Shristi.

You probably won't be too happy with the short or the long answer.

In short, you can't compare tests from two different providers because they use two different algorithms.

The longer answer is that on the test the score has no correlation with the number of correct or incorrect answers. The only pattern and correlation that exists is centered around the number of hard questions answered correctly.

What complicates the scoring even more is the concept of experimental questions the dinner account towards the scoring but then again different test providers have a different idea about the experimental questions and many are almost all not really tell you if they have an experimental questions or how they use them or which of the questions that you were presented with, were experimental.

In conclusion you can't just take the number of Ridarenc and compare them across the board because the difficulty of those questions matter and the position within the test also matters. If you want to learn more about it you can search for Gmat algorithm and GMAT prep what if scenarios on the forum.

PS. What I find odd is the huge difference in your final score. Did you take these tests close together?

Thanks a lot for you reply.
There was about one month difference between the two tests.

Hopefully Kaplan after the GMAT prep

By the way while different prep companies use different algorithms for scoring, usually their scoring is somewhat balanced and reasonable. As with everything there's a margin of error involved so you want to be well above your target score before you call it quits and run to the test center but you get the idea. Congrats and good luck

This link will tell you how scoring is done: http://www.veritasprep.com/blog/2016/06 ... ems-wrong/
The points discussed in detail are:

- The number of right/wrong answers is much less predictive than you think.
- Of the “ABCs” of Item Response Theory, Difficulty Level is Only One Element (B)…
- Question delivery values “content balance” more than you think.
- Some questions don’t count at all.
- Every test has a margin of error.

Hi shristi666,

We can't comment for other tests but do note that no test prep company's algorithm will exactly match the real thing. The best we can do is get close.

You can always take a free GMAT PILL practice test here complete with detailed performance and timing analytics: http://www.gmatpill.com/gmat-practice-t ... ctice-test

In terms of our scoring, many of our students report scores that are +/- 30 points from their actual GMAT test and so are a relatively good indicator of their performance. That said, no practice test can perfectly replicate the actual score algorithm, but this is quite close.

You might find this interesting: https://www.manhattanprep.com/gmat/blog ... mat-quant/

Note that it's based on data from our practice tests! So, like Bill says, we don't know how closely the data matches the real thing - we don't have access to those numbers. But I think our practice tests are a reasonably good representation of the real GMAT - they were vetted by Larry Rudner of the GMAC relatively recently, who gave them his approval, for what that's worth.
