If you do not earn a passing grade on a written formal exam, then you can make a new attempt whenever that exam is offered. Retakes of exams are arranged twice a year. Usually, they are planned for the second half of August and January, but specific dates will be posted on our website in advance. It is each student's responsibility to find out about the dates and contact the relevant course organizer. One can generally sign up for two specific exam retakes at a time. Students who receive a passing grade (G) on any exam may not retake that exam to obtain a higher grade.
