1) If you want to take first-quarter calculus (Math 11, 30, or 35) at SCU, then you must take the CRE unless:
You have college credit for a course equivalent to Precalculus (MATH 9), or a score of 4 or 5 on the AP Precalculus exam. In either case, you can register for calculus without taking the CRE.
2) If you have transfer credit, AP credit or IB credit for MATH 11, you do not need to take the CRE and can enroll in the sequel class.
