for Master Students
A one-semester course for Master students in the Chemical and Energy Engineering program at the Otto-von-Guericke-Universität Magdeburg
last updated July 17, 2018
Dear 2018 students:
I sent the grades for the 2018 exam to the examination office on 2018-07-17; they should be online shortly. I will be offline until 2018-08-02 and away from office until 2018-08-20.
The Einsichtnahme session will take place on 2018-08-21 from 1300 to 1700 in G14-101. I will work alone for that entire afternoon, so I call for your patience with me during that session.
Thank you! Have a nice summer,
