Math Placement

The Math Index is used for math placement at Saint Louis University. It is a number that represents a combination of High School GPA and the ACT or SAT Math scores. The index is based upon research conducted by the Math Department using five years of data looking at success in SLU mathematics courses. While the index provides a reliable tool for math placement, Academic Advisors will consider each student’s situation on an individual basis.

Math Index Formula

ACT:   100*High School GPA + 22.5*ACT Math Score

SAT:   100*High School GPA + SAT Math Score
