Undergraduate courses are generally capped at 18 students. If a class is full you can still register and be added to the waitlist. Students should not “crash” classes and ask the instructor to add them. Based on the number of students on the waitlist and room capacity availability, it may be possible to open the waitlist and allow the first student access to the class. If there is space for 2 students, the first two would be allowed access and so on. If you have questions about accessing the class contact your Advisor.
