Quiz

Answer these questions to get feedback on how well you understand the course. Only one of the answers is correct. You don't have to answer every question. If you don't know the answer you can just leave it blank (default option: I won't answer this question) and this won't affect your score. Answering correctly will add 2 points to your score but on the other hand you'll lose 1 point if your answer is wrong. The questions are divided in groups of five questions.
