12 Maryland: Math Remediation Among MD HS students who took the SAT or ACT in 2008 and who enrolled in MD public colleges or universities: Core students = 3 years of HS Math and 2 years of HS science; Non-core students = not. A remedial math course in college was needed by 32% of core students and 49% of non-core students. Including, at University of Maryland system campuses 14% of core students and 27% of non-core students. And at MD community colleges 56% of core students and 69% of non-core students.
