Conclusion

OSUE is sophisticated

I Spend efforts here and there or only shortly beforedeadlines usually won’t lead to success! ⇒ 4.0 ECTS areabout 6.5h per week.

I Lectures alone are not sufficient to pass the exams! ⇒OSUE. Lectures are introductions, opening up of OStopics through exercises!

I No exceptions to regular procedure of the course! ⇒Fairness for all participants + smooth work load over thesemester for students and teaching staff.
