Over the years we developed a pretty good collection of old exam papers.
Information on these are published every semester at the "FSR Hauptversammlung!" (You can also ask your colleagues, they might know them...).
Of course you can also ask us directly.
Note: The location changed! (May 2016)
This collection needs your help, too! If you have got some exam papers, nice formula sheets or something else that might be helpful, please upload it (or hand it to us) and help the next generations of your study course!
