I'm the first person on the waiting list for the class I want.  Will I get the first seat that opens up?

Wait listed students are added to classes according to priority, not according to rank on the list.  Students in the computer science and pre-computer science majors have first priority.  Minors and students in other majors that require our courses have second priority.  Even if you are first on the list for a course that is not required for your degree program, any student on the list who is required to take the course will be added before you are.
