Hogwarts was mostly unaffected by the reveal considering it was located so far from cities that it was still an unknown place. Which has been good as the school had only recently finished its repair. The school had reopened last year, but there were many parts that were closed. The curriculum had significant revamping and new professors were hired to replace those lost. It needed to accommodate for history and learning of the non magical world, as well as surpassing the lackluster education from before, but overall the school was now on the right track.
