Prerequisites

Entry requirements

For the participation in lectures or exercises: there are no specific entry requirements;
for the participation in practical class: successful attendance to the Safety Instructions (part of the introduction weeks, always in September/October) is mandatory!

Assessment

Modalities of examination

The overall grade for the modul examination consists of

  1. completion of all experiments and writing of two elaborate lab reports (20%),
  2. a  written examination (80%) which has a pass mark of 50% of the points that can be obtained.

Both examination components must be passed.

For the whole module 7 ECTS are allocated.
More details will be explained during the first lecture.
