Harry Potter: Man at Hogwarts but no wand

Introduction: Sincerely, the author: This is an outrageous book, because the plot and characters are drawn by the author, so the author of the plot does not know what will happen every day. The main setting of the movie + there will be some changes in the setting, the combat power will not collapse, the Unforgivable Curse conforms to the original text and has side effects. The setting is a time travel, and Andy comes to the world of wizards, and finally survives Hogwarts after many disasters. Enrolled, but something went wrong?Urgent, wait online, I'm in Hogwarts, I'm going to be sorted soon, what should I do if I don't get a wand.
