The calendar for 2020-2021 is:
All regular courses are taught in blocks of eight weeks, with lectures during the first six (core courses) or seven weeks; the eighth week of each block typically serves as an exam week. In addition, first-year (core) courses have weekly one-hour classes, taught by a teaching assistant, in which students work on and discuss homework assignments.
Deadline for registration is three weeks before the start of the block in which the course is scheduled.
