 It s a hot week, partial exam time; mother-hen Jeanne burns candles for freshman Koen and feeds him cod-liver-oil and some local potion. Odilon is also preparing for a promotion exam in the federal prison service; as he has neither brains nor memory capacity, none of the students sees any point in teaching him a study technique, but even after an initial failure, Jef is convinced to give it another go when Jeanne tells him he makes a highly attractive school-teacher. Billy and the others blow off steam playing with water-guns.
