In general, students receive letter grades in law courses. The dean may determine that pass/fail grading is preferable for a course. Courses that will be offered only on the pass/fail basis are announced before registration.
Courses offered only for a letter grade cannot be changed to a pass/fail grade. There is no limit to the number of courses that can be taken on a pass/fail basis.
A non-law graduate student who enrolls in a law school course offered for a letter grade may register on the credit/no credit basis if permitted to do so by his or her graduate adviser.
