In the summer of 1994, Harry and Dudley encountered Dementors on Privet Drive. Fortunately, Harry had learned the Defense Against the Dark Arts spell Expecto Patronum from Remus Lupin at school. Otherwise, there would have been two more soulless walking corpses in the world.
Yet the Ministry of Magic considered it illegal and sent Umbridge to Hogwarts to "set right" the school's education.
What sense was there in learning knowledge and skills but not being allowed to use them?
Even Hermione, an outstanding student, did not agree with this. She attended the "tutoring sessions" Harry organized, but the foolish students gave the study group the "elegant" name Dumbledore's Army, which became Fudge's excuse to deal with Albus.
They could not be blamed. What could children in their teens understand? Besides, like all adolescents, they did not trust adults. At least, they did not trust Snape back then. Perhaps they secretly missed Remus Lupin, that "Werewolf teacher."
Because Albus practiced lenient teaching, Hogwarts had not produced an Auror for several years. The only one, Tonks, had been admitted as an exception solely because she was a natural Metamorphmagus Animagus.
She was not particularly good at being an Auror or doing housework. The Packing Charm was directly related to a person's housekeeping ability, and when she packed for Harry, it became a complete mess.
