CSAT Score and Percentile Summary

Add Korean, Mathematics and two Inquiry standard scores and compare three-area and four-subject percentile averages.

Usage notes

Enter standard scores and integer percentiles from the same exam score report. Three-area mean = (Korean + Mathematics + (Inquiry 1 + Inquiry 2)/2)/3. Four-subject mean divides their sum by four. English and Korean History have absolute grades without standard scores or percentiles. These summaries are not university-converted scores or an overall percentile rank.
