- hand in exercises. You will receivce the exercise at the end of the class on Tuesday. You have to hand it in one the next Wednsday, when you arrive at the werkcollege. The everage of the marks for all the homeworks will give one mark HW (maximum 10).

- final exam, for which you will receive a mark E (maximum 10).

Note: you are allowed to bring with you, and use during the exam, three sheets of A4 papers (= six pages) containing definitions, theorems, etc from the course.

**Coordinates of the exam:** The exam will take place on Wednesday, November 8th, between 09.00 - 12.00, in RUPPERT Blauw. The retake will take place on Wednesday, January 3rd 2018, between 09.00 - 12.00, in the math building (HFG), room 611B.

** Final mark:** The final mark will be obtained by combining E (exam mark) and HW (homework mark), by the formula:

max{(7 E+ 3 HW)/10, (17E+ 3H)/20}
