Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

BMT2304.KON (P213-0028) Biomedical Engineering, Bachelor, ASPO 01.10.2018 , semester 3, mandatory course
BMT3304.KON (P213-0231, P213-0232) Biomedical Engineering, Bachelor, SO 01.10.2025 , semester 3, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
75 class hours (= 56.25 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 93.75 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
None.
Recommended as prerequisite for:
Module coordinator:
Prof. Dr. Moritz Habschied
Lecturer:
Prof. Dr. Andrea Bohn
M.Eng. Julian Guckert
