Math 165 Introductory Statistics is a 4-unit transfer-level class, transferrable to the UCs, CSUs, and many private universities. Math 165 Introductory Statistics with Corequisite Support is two classes/CRNs: the 4-unit transfer-level Math 165 Introductory Statistics class, and a 2-unit Math 065 Corequisite Support class, which is basic skills (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 (next to each other).
