12. Cheating and Plagiarism
Do not!
Studying together to understand the material is fine, but the work you hand in is to be your own.
No cheating will be tolerated: A letter grade of F will be given!
You can constitute a group of maximum three students to submit assignments. You may submit a unique report for your group (of course plagiarism among assignment groups is strictly forbidden).

13. Mobile phones
It is strictly forbidden to use mobile phones for any reason (watch, talk, chat, ituportal, whatsapp etc.) during the classes
Please turn of your computer or turn it to silent mode.
Keep it in your bag.
Do not hold it in your hand or on the desk.
