Hey,

I scored a 690 in total, 48Q and 38V. Now I read in the "I beat the GMAT"-forum, that someone with 46Q and 38V also got a 690 (https://www.beatthegmat.com/viewtopic.php?t=4421)... how is this possible? This is a difference of 2 points!!

And now the most frustrating thing: In the "I beat the GMAT"-forum there is also someone, who scored another 2 points more (50Q and 38V), and got a 740 (https://www.beatthegmat.com/viewtopic.php?t=4962)... ahhhh!!!

Does someone know an answer, or should I perhaps contact GMAC?

Don't try to interpret the algorithm. Different raw score combinations can produce slightly different total results--sometimes depending on day or season. I haven't quite figured it out myself.

Be proud of your 690!

You receive scores in Q and V with internal decimal places, such as 47.5 and 37.5. These are rounded to 48 and 38.

curve

Also, GMAT scores are curved based on the population of test-takers at that time in that general geographic area. The curve doesn't make too much of a difference -- the same Q and V scores aren't going to be off by more than 10 or 20 points most of the time -- but there can be slight differences, even in the same place a few months apart.

FYI the scores and percentile rankings are NOT based on geographic area - they are valid for the entire population of test-takers, worldwide. They can (and do) vary over time, however.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
