The course has restricted admission. A prerequisite for starting studies is a first university degree, with the required necessary background education as determined in the exam regulations.
In brief, you need Bachelor's degree in Mathematics, Computer Science, Physics, Electrical Engineering or a related area, whose curricula include the modules Analysis I + II, Lineare Algebra I, and Stochastic I that together comprise 30 ECTS and were taught at a level that corresponds to the level for computer scientists at HHU. The exam board determines whether you fulfill the entrance requirements.
The final grade of your bachelor's degree must not be below 2.5 with respect to the German grading system. You can convert grades to the German system by using the 'Bavarian Formula', see https://www.tum.de/en/studies/application/grade-conversion-formula-for-grades-earned-outside-germany/
