I added a collection of exams. It is not complete, and may be extended later, if time allows. Solutions are currently /not/ shown, as they the collection is intended to help preparing for the exam. That's best done by solving them by oneself (or at least attempting to) without having immediately the solution at the fingertips as well.
I uploaded the last batch of the slide + a pdf containing all the slides of the lecture. No more additional material will be added therefore (but there may be additional slides concerning exercises or old exams).
