Score Mapping and Change from Unofficial to Official?

Question

I just completed the GMAT Online and scored a 710 (Q49 V40). I'm happy with the result, but when I cross-referenced the score against the score charts of TTP, Manhattan Prep, Magoosh, and Menlo Coaching, my score equates to a 720/730. Is there a chance my overall score will increase from the unofficial 710? Is there anything I can do?

Hey  GmatKnightTutor , I see that someone else was in the same position, same score too, but his post shows that someone else on the same day (online too) scored a 730 with the same Q/V. I haven't seen/heard of someone contesting a score based on what scores others have received for the Q/V. Is there an example of this?

I think they took the chart from one of our users https://gmatclub.com/forum/gmat-scores-83890.html P.S. No, you cannot dispute it because if you dig in deeper, the algorithm for calculating the Q49 and V40 is different from the algorithm that calculates 710. That is why it is possible to have it as a 710 or 720. This means you got a low Q49 and a low V40. Some rounding up/down resulted into 710. This is not a test mistake unfortunately. Sorry! Congrats on a 700+ though!

Hi 500levelsavant.

You GMAT total score is based on your performance on the Quant and Verbal questions on your test, rather than on your section scores.

Also, each Quant or Verbal section score represents a range of possible performance on a section. For instance, you can score Q49 with 22 correctly answered Quant questions or 20 correctly answered Quant questions. So, the fact that two people got the same section scores doesn't mean that they performed at the same level or will get the same total scores.

In fact, each pair of section scores can be associated with two or three different total scores. So, as you've seen, Q49 V40 can be associated with 710, 720, or 730.

Hi 500levelsavant,

That's a very good score! If you're interested in knowing why the same section scores can lead to different total scores:

1. The GMAT generates a score at the end of both the quantitative and verbal sections. These scores are on a continuous scale.
2. These scores are mapped onto an internal scale. Let's call these scores "internal scores".
3. These internal scores are combined to arrive at a total (internal) score.
4. All these scores are then converted to the scaled scores that are exposed to the test taker (6 to 51 for quant and verbal, and 200-800 for the total).

The internal scales are slightly more accurate than the ones exposed to you.  For example, let's say two people got a Q49 each. Now, a Q49 could indicate a performance level anywhere between 72% and 86% (Q49 is 72%, and Q50 is 86%), so it's entirely possible that one of them got a "low" Q49 and the other got a "high" Q49. This is the reason that you don't always see the same total for the same score combinations.
