There are actually two different types of GRE Quantitative scores: a scaled score (on a 0-800 scale) and a percentile rank (from 0% to 99%) — although only scaled scores are reported to the schools. One way to compare your performance on practice tests to that of other test takers is to calculate a raw score, which is simply the total number of questions you answer correctly, and then use a table to convert that number to a scaled score and percentile rank.
To gauge your performance on the 34 GRE Quantitative practice questions at this site, keep track of your raw score for all three practice sets. Then use the following table to convert raw score to scaled score. You can also estimate your percentile rank using the same table.
[How to Interpret the Table]
NOTE: An actual GRE Quantitative section consists of 28 questions. Use the below table only for the 34 Quantitative practice questions at this site.
..raw score | scaled score | percentile rank 34 ---------- 800 --------- 99
33 ---------- 790 --------- 98
32 ---------- 780 --------- 96
31 ---------- 760 --------- 94
30 ---------- 740 --------- 92
29 ---------- 720 --------- 89
28 ---------- 700 --------- 85
27 ---------- 670 --------- 81
26 ---------- 640 --------- 77
25 ---------- 610 --------- 72
24 ---------- 590 --------- 67
23 ---------- 570 --------- 61
22 ---------- 540 --------- 55
21 ---------- 510 --------- 48
20 ---------- 490 --------- 41
19 ---------- 470 --------- 35
18 ---------- 450 --------- 30
17 ---------- 430 --------- 25
16 ---------- 400 --------- 21
15 ---------- 370 --------- 17
14 ---------- 360 --------- 14
13 ---------- 350 --------- 11
12 ---------- 330 --------- 8
11 ---------- 310 --------- 6
10 ---------- 280 --------- 4
9 ----------- 250 --------- 2
8 ----------- 220 --------- 1
6-7 --------- 210 --------- 1
0-5 --------- 200 --------- 0
How to Interpret the Table- Quantitative scaled scores are based on a 200-800 scale. (There's nothing magic about this number range; it's just GRE testing tradition.)
- Percentile ranking (0% to 99%) shows how you performed relative to all others taking the GRE over a recent multi-year period. A percentile ranking of 60, for example, indicates that you scored higher than 60% of all other test takers (and lower than 40% of all other test takers). NOTE: Percentile rankings are not reported to the graduate schools.
- One additional correct response makes the biggest percentile difference near the middle of the performance "curve" (because it's a typical bell curve).
- If you missed 5 or fewer questions out of 34, expect to rank in the top decile (10%) in GRE Quantitative Reasoning.
- If you responded correctly to 21 questions out of 34 questions, expect to rank near the 50th percentile in GRE Quantitative Reasoning.
