Math 180 Calculus for Business and Social Sciences is a 4-unit transfer-level class, transferrable to the UCs, CSUs, and many private universities. Math 180 Calculus for Business and Social Sciences with Corequisite Support is two classes/CRNs: the 4-unit transfer-level Math 180 Calculus for Business and Social Sciences class, and a 2-unit Math 080 Corequisite Support class, which is a basic skills course. The corequisite support class is graded Pass/No Pass. These two classes are linked so students must add both CRNs (course registration numbers) to their schedule. The classes are scheduled sequentially, one right after the other.
