Exam topics

oral exam. At the beginning of the exam each student will be distributed two questions (one from lectures, another either from lectures or to resolve one of many exercises in lecture notes). After preparation under surveillance (no access to books, notes or internet, smartphones forbidden), students will be called one by one for questioning. I reserve the right to continue questioning beyond the two initial questions. Count on ~1h preparation and 1h questioning. Paper for preparation and the exam will be provided, bring just a pen and an ID.
