Julia: To get the highest mark in the class you have to understand everything you memorise.
Dieter Meier: Do you have to review everything before the exam?
Julia: Of course! You will also need to redo all the exercises.
Dieter Meier: Do I also need to make a summary of the lessons?
Julia: Of course and you need to prepare an outline of the class.
Dieter Meier: It would probably be easier if I just copy the exam from you.
