The objective of covering 18 CP in an application field is that students obtain in-depth knowledge and skills in the chosen field, thus extending their knowledge beyond the scope of Computer Science.
All application fields that are admissible for the Bachelor’s degree program in Computer Science are admissible for the Master’s degree program. Details about these areas can be found here. If you already had an application area in your bachelor's degree program, you are not allowed to bring respective modules from the bachelor's degree into your master's degree studies.
