Mr. Donohue may have a tough exterior but he truly cares about whether his students learn. He can be harsh, cruel, even seem heartless but that's because he sees the potential of a stubborn student who is to lazy to do his homework. He gets mad when people aren't working as hard as they can. If you walk into his class with with a cocky know it all attitude he will tare you apart. Now I have the Don as a Procter for two of my exams yeah me.
