Exams in Measure and Probability

Exams in Measure and Probability are, in principle, both oral and written. While Corona rules impose restrictions on in-house written exams, exams for lecture semesters 2021 and later will be oral only.

Now (summer 2022) Corona restrictions have been lifted to the extent that made it possible to announce written exams again. Therefore, since April 2022 exams are in written+oral mode again (until further notice). Since April 1, the “early exam” restrictions on material in Probability and Measure 2 are no longer in effect, so chapters 6 to 14 are relevant now for both formats. The precise format is as it was before Corona restrictions: in the written part you will be given four problems, a mixture of theory and “applications”, some selected theorems with proofs (see problem collection and list of proofs below), the oral part focusses on theory: important theorems and definitions, no detailed proofs, maybe one or the other idea of proof – the review questions at the end of each chapter should give you an idea of how exam questions look, but by no means these should be considered an exhaustive list.

Probability and Stochastic Processes for Computer Science

will only have oral exams during the Corona period and afterwards, as the TISS announcement says. This, of course, means a shift in the theoretical direction. If you have successfully taken the written part already, it is still valid, and the oral exam will be less detailed than without.

Oral exams

Oral exams will be given by video conference via our jitsi-meet server. This needs some technical prerequisites:

  • PC, Laptop, or mobile device with
  • camera
  • microphone and
  • sufficiently fast and stable internet connection
  • Chrome or Chromium as browser – others work, but may have small issues.
  • Chrome also on mobile devices – tablet/smartphone – the Android and IOS apps still have problems, although the very disturbing connection problem has been resolved; now we have the issue that sound and video do not seem to be forwarded to the other participants. So, please ignore the request to install/start the app and click on the “join on the web” (or similar) button at the bottom.
  • You will be given the link for the exam a day in advance.

As for the procedure:

  • In the beginning, you must present your ID.
  • Oral exams are public by law, so you are free to invite observers, and persons interested in watching an exam can also contact me. Any observer must be announced to me, there is a limit of at most ten persons watching, persons physically present in the room where the exam takes place must stay visible during the entire exam, and those watching over internet must turn their cameras and microphones off.

At any rate, if you would like to take an oral exam or be given a take-home assignment, contact me by e-mail. There will be 2-3 “official” exams per semester, but you can request an individual one (almost) anytime.
