Dear Mohammad,
the exam number for 7.5 ECTS is 278169 (Programming Techniques for Supercomputers (Lecture and Tutorial)) while
the exam number for 10 ECTS is 58751 (Programming techniques for supercomputers in CAM).
As a CE student, you should be able to see both exams (the 7.5 ECTS module for example refers to two M.Sc. CE with PO 2013 and PO 20252, see this link).
If 278169 doesn't show up for you, please contact your CE student service center (Dr. Schmutterer).
