[Wizarding World] How does Hogwarts get muggle born wizards to suddenly believe in magic when they get their invitation letter. Better yet how do they figure things out like currency, platform 9 3/4s, and Hermione somehow being an expert before even getting onto the damn train.

Can’t remember where, but I’m pretty sure the school will actually send someone to explain it all with the Hogwarts letter. Kind of like Hagrid did with Harry, although probably a bit better. Hermione knew so much because she read it all after she was taken to Flourish and Bouts and bought a book like the nerd she is.
