Will more courses be added to the list and till when will the course end ?

The complete course list will be published soon and also shared with you via email before course registration starts (around mid-December). The end of the Spring semester is May 5 2023 - if you're a Master student, you may also have final exams from May 9 to 19 2023.

If i am an undergraduate student that will have final exams, will i also end on 5th May ?

I am an undergrad student so would the course end on May 5 for me as well?

For undergraduate students, you may have a few final exams from 18 February to 27 February and then the rest of your final exams from 11 April to 15 April. You might finish your semester in April if you don't take any intensive courses after that date (depending on the number of credits you need). If you still need credits, you can select intensive courses that will be offered until May 5 (with final exams possible on May 10).
