Usage notes
Percentile = (candidates with lower standard scores + tied candidates/2)/subject candidates × 100. Include yourself among ties. Use integer standard-score distributions and round the final percentile to the nearest integer. Do not substitute raw-score ranks or total CSAT registrations. The same rounded percentile can correspond to different grades, so no grade is inferred.
