Prerequisite/Placement Scores
Early College Program students who wish to take a college-level English, chemistry, math or physics courses need to have completed a prerequisite in order to register for the course. Placement can be satisfied with either the prerequisite course or an ACT, SAT, Compass, or ALEKS (Math) test score. Passing placement scores need to be submitted to the Early College Program or the Admissions Office prior to registering for the course.

ISU Math Placement
All mathematics courses except MATH 0015 have prerequisites. Students place into a course by completing the prerequisite course(s) with a grade of C- or better or by achieving appropriate scores on the math portion of the ACT/SAT exam, Compass mathematics, or ALEKS placement exams.
Students should review the math requirements for any majors they are considering at ISU or elsewhere. Only certain mathematics courses will meet Objective 3 at ISU or general education mathematics at other colleges and universities. When considering enrollment in a math course, we recommend that you speak with your instructor, the Early College Program, or advisors at other universities or colleges you are considering.
Students should plan their mathematics coursework according to their intended majors. Some majors, for instance, require MATH 1153, and others require MATH 1160. Students planning to take calculus must be especially careful to determine whether MATH 1160, Brief Calculus, or MATH 1170, Calculus I, is appropriate. Taking one after the other counts as a repeat and provides no further credit toward graduation.
