Hi tzurohad,

The ManhattanGMAT CAT exams attempt to be as accurate as possible; however, these exams are subject to a slightly larger standard of error than a real GMAT, which could explain why your most recent score rose slightly. The GMAT has a standard error of 30 points while our exams have a standard error of 50 points. Hence, because your scores fall within this range, your "true score" is most likely a 670 - 680.

The topic of how to understand your complete practice test scores on ManhattanGMAT exams has been discussed on these forums for quite some time. In short, while it is a major student concern, students should be more focused on analyzing their specific strengths and weaknesses located in ManhattanGMAT Assessment Reports rather than looking solely at their practice test scores. Looking at your Assessment Reports will provide you with insight into your weaknesses, allowing you to review the appropriate sections accordingly.

Best,
