Certificate
Scores, percentiles, APS
Two 0–200 scales with a mean of 100, a percentile, no pass mark. The certificate does not expire.
The two numbers
Each module is converted from raw correct answers to a dMAT score between 0 and 200, standardised so the mean across sitters is 100. A percentile says what share of other participants scored lower or equal. Universities may set a cut on either number. This desk approximates the conversion as linear in accuracy (50% → 100) and the percentile from a normal model with mean 100 and SD 28. Official scores use the live cohort; treat our numbers as a rehearsal scale.
What APS does with it
You enclose the g.a.s.t. certificate with the APS file. The score is referenced on the APS certificate. It is additional information. It is not a pass/fail gate for APS itself. A weak result does not stop the certificate from being issued.
Validity
The dMAT certificate is valid indefinitely. You can download it from the participant portal once results are out (first sitting: 12 October 2026).
