If any Biology, Ecology or Evolutionary Biology (EEB) or Molecular, Cellular and Developmental Biology (MCDB) course becomes full, students are strongly encouraged to use the waitlist. Overrides will be issued at the discretion of the instructor for a given course, prioritized by a combination of the student’s concentration, class schedule, and their order on the waitlist. Students on the waitlist must attend the first day of class or discussion and notify the instructor or GSI of their desire to enroll in the course. If an override is granted, students will receive an email notification so they may register for the course prior to the stated expiration date. The Registrar’s Office will clear waitlist of students’ names with expired overrides.
