Getting help with the assignments
E-mail the teaching assistant and schedule an appointment.
When working intensively on an exercise, it's hard to predict exactly when questions and issues will crop up. Getting help by appointment is more flexible than regular exercise classes, and lets you get help when you need it, rather than at a predetermined time. Scheduling in advance ensures that the teaching assistant is available when you come to get help.
Assignments can be done in groups of 1 to 2 students.
