I was able to see my course on Blackboard, but it no longer shows.

Check CUNYFirst to see if the professor of the class gave you a WN grade.

Students are added back into the Blackboard course within 24 to 48 hours after the WN Grade Reversal form has been approved.

Instructors are required to report students’ attendance after the 3rd week of classes. If you did not attend, the college assigns a WN grade for the course.
