Math 175 Precalculus is a 6-unit transfer-level class, transferrable to the UCs, CSUs, and many private universities. Math 175 Precalculus with Corequisite Support are two classes/CRNs: the 6-unit transfer-level Math 175 Precalculus class, and a 2-unit Math 075 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.
