Surprisingly, Tom Marvolo Riddle had turned out to be quite a good teacher. He was patient if you couldn't grasp a concept but didn't allow tardiness. His punishments were vicious if he thought you not paying attention. It kept you on edge, making your brain work twice as hard. All in all, Harry was as proud of his own progress as he was of Fred's and George's. If he was lucky, he wouldn't even have to take Defence next year. Considering that the school board still believed in the curse, there was a good chance that Severus wouldn't be assigned the post again, no matter that he had circumvented it by changing the classroom. Also, Harry had a little early present for the man, but he wouldn't reveal that until the first day of September. McGonagall knew, of course. Severus, however, had no clue. Harry was looking forward to that particular revelation.
