Office hours: to be determined directly with the students

Lectures and werkcolleges: Alternating Mondays or Tuesdays, HL204, 13:45 - 16:30, but there are exceptions (see timetable); Thursdays, HL204, 09:00-10:45 (also with exceptions). The problem sessions are interactive. The material covered in the problems constitutes an essential part of the programme.

28/11 A take-home exam for extra credit is available from Andrey or Ana. It is due on Monday December 19th (three days after the final exam). To get a copy of the exam come to our office, or send us an email in which you state that you understand you are not allowed to communicate with other students about these problems.

Final exam: Friday 16/12, Huygens 106/107, 09:30 - 12:30

It will be a written exam. There is a first part without book (about one hour) and a second part with open book. To the first part you can bring a one-page summary (formulas, etc). The conditions for the second part are: you can bring a) Carroll and another book, b) your own handwritten notes from lectures and werkcolleges (including your own solutions to the problems - no photocopies), e) a calculator.

The final grades for the course can be found here . Please contact me (by email) if you want to check your grading and/or if you are intending to take the resit exam.
