Hi,
Normally students score within about a +/-30 point range of their test scores' average. One test score does not say exactly where you are at; take a few of them, average them out, and that is a fairly good indicator of your level.
I would like to refer you to the following articles on scoring:
https://econgm.at/Bd56c6https://econgm.at/hEut0lAlthough most students score within the 30 point range mentioned above, if you keep studying you will be able to break out of this and advance to higher grade. Try to get as much official practice material as you can such as the Official Verbal and Official Quant Review, or the question pack 1, previous editions of the Official Guide for GMAT Review (12th and 13th editions are best), all from mba.com. If you more questions, please feel free to ask me.
Sincerely,
Evan
