Students may take classes that are not required for the degree, as long as they do not interfere with required course work and the minimum 3.0 GPA is maintained.  Courses taken for Pass/Fail or R Credit will not count toward graduation. 

A student registered for a full RU (Residence Unit) or ER (Extended Residence Unit – required after completing two RUs in GSAS) may take up to and including 20 points.  Extra fees will be charged if more than 20 points are taken at any point, even if classes are dropped later on.
