What in the world kind of class are you taking!? Exams are LESS STRESSFUL than COURSEWORK!? ONE EXAM IS 20% OF MY GRADE! I much, much, much prefer coursework (we call it homework in the US) to exams. There's no studying; once it's done, it's done. And there's generally not that much of it. Plus, it doesn't count for nearly as much of one's final grade.
