You can change to or from pass/fail an unlimited number of times during
online registration in the first twelve class days of a long session
(fall & spring) or the first four class days of a summer session.
After the online access period, you need to go to the Student Division,
GEB 2.200, to change a course to or from pass/fail. During this period
you can only change the pass/fail status of the course once and this
must be done by the mid-semester deadline.
