Grade Mode Deadlines: Spring 2026
The 91次元's deadlines for changing grade modes (switching to or from credit/no credit grading) in the spring semester are posted on this page. Students are responsible for adhering to all published registration deadlines.
The credit/no credit grade mode allows students to earn credit for classes on a pass/fail scale instead of receiving a traditional letter grade. Not all classes are offered with the credit/no credit grade mode. Credit/no credit grading is different from auditing, which allows students to sit in on classes without earning credit.
