The new exercise sheet will be uploaded on this page on Monday. You are supposed to have a look at it before the exercise class, so that you can ask questions if you need to. You have time until the following Monday at 12:15 to upload your solutions.
Please, upload your solution via the SAM upload tool.
In order to access the website you will need a NETHZ-account and you will have to be connected to the ETH-network. From outside the ETH network you can connect to the ETH network via VPN. Here are instructions on how to do that.
Make sure that your solution is one PDF file and that its file name is formatted in the following way:
solution_<number of exercise sheet>_<your last name>_<your first name>.pdf
Example:
solution_2_Surname_Name.pdf.

Date: Saturday, February 5th (05.02.22).
Time: 9:00-12:00. The doors will open at 8:30.
Location: By LAST name:
From B to H in room F3 of the main building (HG)
From K to Z in room F1 of the main building (HG)
Special Rules: Wear a surgical or FFP2 mask. Please bring your student card (legi) and your valid Covid certificate (3G), PRINTED.
The exam consists in 3 parts. You can decide in which order to solve them and how to manage your time.
Part 1. Multiple Choice, in the style of Exercise Sheet 12.
Part 2. Two exercises, choose one. You will be presented with two exercises similar to those in the Exercise Sheets, or to examples seen in class.
You have to choose one, and solve it. If you hand in both solutions, we will grade the first one that we find and ignore the second!
Part 3. A slightly more challenging exercise, based on the material covered during the semester.
No written aids are allowed. Please bring your own paper and write your solution in either black or blue (no green, no red, no pencil). Bring your own Tipp-Ex to use during the Multiple Choice part of the exam. Don't use a Tipp-Ex for the open exercises (Part 2 and Part 3).
The exam took place on Saturday, February 5th 2022. Here you can find the Multiple Choice exercises as well as the Open Questions.
