The twins are daydreaming and are surprised by the announcement that exams are about to start. Suddenly Hanni and Nanni become very eager. But their grades are mediocre, which is all the more disappointing because their father expects his two daughters to be among the best. Nanni accidentally gets hold of the exam papers for geography, the last exam still to be taken. Hanni tries to convince her sister that she should report to Miss Roberts, the class teacher. The next morning, she discovers that the papers have been mixed up.
