Dear Students, 

we just released the Final 1 grades on CMS. We also uploaded a solution in the materials collection. 
For inspection, we will have a 2 stage process: i) on-demand, we will mail you scans of your exam, ii) for those that looked at their scans and have further questions, there will be an on-site inspection, tentatively on Friday 20.2. at 9am. Details will only be release to people who registered for the on-site Inspection - we cannot entertain walk-ins due to the large number of students taking the class.

If you want a scan of your thesis, please register for it here on CMS, we added a new registration option. Registration deadline is tomorrow, Tuesday 17.2. 17:59pm. Scans will be sent that evening. Please request scans only if necessary, as the process involves a lot of manual effort for everyone involved.

We will create a second registration for on-site inspection afterwards. Only people that requested their scans before can register for the on-site inspection.

Regards,

Nils

To avoid additional short-term stress for a mistake that we made, we extended the deadline of the current project to 10.12.25 23:59. Please note that this will not change the release or deadline of the next exercise sheet.
