Thanks to the tutors who graded until just now, we are happy to release the exam results. You should have received an email about this just now.

If you have a grade bonus, the final grade is shown in the lower part of your Personal Status page (since the grade bonus applies for the main and backup exams).

For the inspection, we will host this at CISPA's main building on campus this Friday, from 13:00 to 15:00. More details will follow later this week.

Seating plan

Written on 14.02.25 by Ben Stock

Unfortunately, due to some bug in the CMS, you cannot see your seat assignment in the Personal Status. I have thus uploaded the seating plan in the Materials -> Exam Preparation section of the CMS.

Clarification on cheat sheets

Written on 05.02.25 by Ben Stock

As you can likely see from the sample exam we shared on the CMS, a cheat sheet will very likely not help you much in either case. That is, you may not bring a cheat sheet to the exam.

User-study information and Sign-up

Written on 04.02.25 by Jonas Schmitt

Dear Students,

My name is Jonas Schmitt and some of you might know me as the teaching assistant of the lecture. In pursuits of my Bachelors thesis I am conducting a user study on SSH usability. For this study I need participants and would be happy if many of you could participate. There will be a compensation of 25€ for each participant and the duration is estimated to be between 30 minutes to an hour. If you are interested to sign up for the study please use the link below and I will contact you via E-mail to schedule the appointment.

Don't stress about your SSH knowledge for this and please don't try to stack up on your skills. This is not a test setting, we just want to understand the usability of the system better.

I am looking forward to seeing many of you and have cool interviews.

Best

Jonas Schmitt

Tutorials this week

Written on 27.11.24 by Jonas Schmitt

Dear all,

Due to the fact that there are no lectures this and the following week we decided to offer a tutors' exam tutorial in the regular time slot this week. The tutors will go over exam-like exercises about the topics covered up until this point. Next week however we decided to not offer a tutorial at all. Please note that the next exercise sheet will release alongside the python exercises at the regular time after the next lecture.

Best regards

Extended Python deadline

Dear all,

Dear all,

We will therefore extend the task deadlines by *two* days to Wednesday, 23:59 (since I hope the issue will be fixed Monday morning).

Deadline issue

Written on 04.11.24 by Ben Stock

Hi all,

due to a misconfiguration, the due date for the second exercise sheet was wrong. I changed the deadline to reflect the correct date: Monday, 23:59 (that is, you can still update your solutions now if you already uploaded them or actually send them in if you did not make it in time before).
