Most of Ohio State's high-demand courses have course enrollment policies set at the department or course coordinator levels. See below for instructions and contact information to help you seek permission for these classes.
For most other courses you can to ask the instructor for permission over the seat limit (through the Friday of week 1) or for late enrollment permission (through the Friday of week 2). You can find an instructor's name on the Class Schedule in My Buckeye Link.
Waitlists are active through Friday of week 1 of classes each term. After that date, most high-demand courses have instructions on actions that should be taken by students still seeking enrollment.
Students with questions about permission for Physics classes should contact the appropriate Physics course coordinator, which can be found on this Physics webpage.
