I'm a student from Germany and currently preparing for some exams. I got an email from one of the professors that contains information about the cheat sheets you are allowed to write and use in the exams. These consist of four DIN A4 pages (so default writing paper) you can write your “Formelsammlung” (formulary, literally: “formula collection”) on. This is important, since the issue is, what does he mean by this?
Depending on the professor, this can mean anything from “Really only formulas, if you write a single word, it will be counted as an attempt to cheat” to “Do what you want with it, I couldn't care less”. Most professors go with a more liberal approach, but there are some who don’t want anything but formulas. What almost all exams have in common is that you are allowed to use one of those cheat sheets. Usually I would just ask the professor, but he explicitly stated in the mail that he refuses to elaborate on that:
Ich werde auf Nachfragen der Art „Was darf auf die Formelsammlung?“ nicht antworten. Eine Formelsammlung ist eine Formelsammlung.
(I will not answer questions in the style “What is allowed on the cheat sheet”. A formula collection is a formula collection.)
Which is the cause of my question: If the professor refuses to answer, what becomes fair game?
Due to numerous complaints the professor has just written another email. He clarified what he meant, which was: No examples of appliances of formulas with example numbers, and no labeled graphs. I assume no circuits either, but now I know that I can at least put somewhat descriptive labels on my formulas and put graphs without labeling.
Zahlenwertbeispiele, konkrete beschriftete Skizzen o.ä. sind NICHT erlaubt.
