There are three exams in this course. They are take-home exams that must be worked out individually by each student, without the help of any other person (no cheating!). The grading of exams follows the grading of the Exercises, i.e., your score is based on the correctness of the solution and on the logic and clarity of your writing. Recall the basic guidance for receiving full credit: the solution submitted must be understandable of and by itself to someone knowledgable in the subject without any need to consult the text of the problem or guess the calculation and reasoning.
