Marshall University has made grading changes for the spring semester because of problems brought about by the coronavirus pandemic and the change to online classes. The university said in a news release that undergraduate students will be able to choose “credit/no credit” grades for this semester only and students have to opt in by April 24. To earn credit, students must receive a final letter grade of A, B or C. A final grade of D or F will result in no credit. Grade point averages won’t be affected by the system. No credit grades do not count toward graduation.
