Evaluation

This course is compulsory to complete the Physical Chemistry and Theoretical Chemistry block. It is worth 5 credits or ECTS (2 SWS Lecture plus 2 SWS Exercises). To pass the course, it is neccessary to write the 2 examinations, which will be done in the middle and at the end of the semester. The exact dates will appear here at earliest convenience.
  • First examination, 50% :6 June 2005, 8:00-10:00 in the Seminar Room, Inorganic Chemistry. RESULTS.
  • Second examination, 50%: 25 July 2005, STARTING TIME: 8:30 in the Horsaal A, Takustrasse 3. RESULTS.
  • Retake examination, 100%:

    15th August 2005, STARTING TIME: 9:00 in the Horsaal A, Tak. 3.

    Note that only those students who participated in the first and second examinations are allowed to retake the examination. If you passed the course, but you want to repeat the exam to get a better grade, please come to my office first. Exam revision and discussion Monday 8th August at 14:00. Final grades will appear on this page on the 9th of August.
