Hello! Did you notice the text in the blue box at the top of the score calculator page? Here's what it says:
https://www.manhattanprep.com/gmat/gmat-score-calculator/Did you know? It’s possible for one pair of sub-scores to map to as many as three different Total scores. For instance, if you look up the pair of scores Verbal 41, Quant 49 on the table, you will see a score of 730. On the test, though, this pair of scores (V41, Q49) can actually map to a 720, a 730, or a 740. Click here to learn more.
So, yes, a specific score pair can map to a 570, 580, or 590. (And different score pairings can map to the same Total score.)
If you'd like to know more about
why this can happen, go back to that page and cick on the link. (It's fairly technical. You can also just know that this does happen and the reasons are valid—and maybe you don't really care to learn the technical details regarding exactly why.
