680, 690, 700 Scores - How does GMAT Calculate this??

[asilrene]

How is (49Q, 33V) equal to 690 , but (47Q, 37V) is equal to 680? Is the quantitative weighted more heavily in the total score?

Is there somewhere I can look that will show which combinations of raw/scaled scores will equal the GMAT final score, i.e.

(49Q, 33V) -------690
(47Q, 37V) -------680
(48Q, 39V) -------700
(45Q, 45V) -------???

I don't believe one section is weighted more heavily than the other, but the raw scores and percentiles are different in quant and verbal (in a nutshell, fewer people reach high verbal scores).

The actual calculations are not published by ETS, but here are some observations: Quant raw scores have been climbing, and it now takes a 51 to reach the 99th percentile in quant, while a 48 (just 3 points lower!) now represents only the 87th percentile. By comparison, in the verbal section, there is a 7 point difference between the 99th and the 87th percentile (45 vs 38).

I have collected some empirical evidence to share with my students and to give them an idea of where they need to aim in each section to reach a specific total target. The following is based on data I've collected from the debriefing posts on this website over approx. the last 5 months. For the same overall score, results are sorted by decreasing quant score:

%tile	Score	Quant	Verbal
99th	760	50	42
	760	49	46
	760	47	47
	750	50	41
	750	49	44
	750	48	44
98th	740	51	38
	740	50	40
	740	49	42
97th	730	50	38
	730	49	41
	730	48	42
	730	47	42
	730	44	47
	720	49	40
	720	48	41
	720	46	43
	720	42	47
95th	710	51	35
	710	49	38
	710	45	41
	710	42	45

Thanks for the info, Ursula! I'm curious why ETS wouldn't publish its method of calculating the total score. Is it that big of a secret?

This site would probabely help you... it gives the conversion method and table for raw scores, scaled scores and the final scores

According to my calculations,
Multiply your Quant scaled score by 9
Multiply your Verbal Scaled score by 7
add them up.

I found out the nos. after making simultaneous eqs from my gmat practice test scores.
hope this is helpful.

forgetmenot0422: The GMAT is administered by GMAC, not by ETS. ETS does the GRE.

GMAC does not reveal its algorithm it uses to determine scores.

I have tried to make a score chart for the GMAT that should be within +/- 20points (see link below)
