Transitioning from high school to Uuniversity, a new academic system, a new country, and other situations can be very challenging. Failing a course can happen. First thing is to talk to an academic advisor. There are a couple of options that students have. First-year students have the option to do rewrites or go into the extended program. Upper-year students might have the option of writing a supplemental exam.
