Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
It is somewhat low... Q40 sounds too small of a score for 10 mistakes taking into consideration some of the GMAT Prep results I have seen but every test prep company has a diff algorithm (mostly because GMAC does not release the official algorithm).
I would probably only rely on GMAT Prep and MGMAT at this point and even with those I have seen some inconsistencies at the end.
P.S. I do agree with you having said all of that. Should be higher.

Thank you for your reply.
I dont usually take these test seriously, I was just surprised and started to question myself. Numbers of questions I got wrong on Quant were: 9, 10, 16 (exp), 22, 26 (exp), 28, 29, 33, 36, 37 and on Verbal: 3, 6, 7, 9 (exp), 26, 27, 34, 37. And since I read about posts, with scores significantly higher and with more mistakes, I wasnt sure what to think about this.
One item to consider is that your score may still be good/correct/valid but the ratio of the mistakes to the final score is off.
However, if Princeton has a larger number of medium/lower difficulty, then to keep the algorithm on par with the official test, is to reduce the number of questions that can be answered incorrectly. There are basically a few variables and biggest ones of them are Difficulty and Correct/Incorrect.
