Maybe you aspire to be a great wizard. Maybe your a power-hungry deformed old man. On the other hand, you might just like all those fun Latin-sounding words that make strange things happen. Whatever the case, what makes you a good candidate for Hogwarts? Are you truly ready to begin you magical journey?
Attending Hogwarts requires that you have a strong stomach. Nobody likes the smell of puke in the middle of a classroom. Scary, strange, and beautiful things happen at Hogwarts, you must be prepared. If you absolutely must attend the famed wizardry school with a lurching stomach, at least have the sense of mind to bring a change of clothes and a clean-up spell. In fact, this is good preparation for anyone who will be attending Hogwarts. It’s always uncertain where a nice stream of puke is going to land.
Secondly, having a dysfunctional family automatically makes you a good fit for Hogwarts. Muggles like their controlled and orderly world. That’s one reason they keep them away from magic. The crazier your family is, the better it is. This will help you make friends with your fellow classmates. Considering the dangers you may face at Hogwarts, you will be in need of at least a few good friends to watch your back and protect you from wand-wielding bullies. In fact, that is essentially how Harry Potter was able to survive. Without friends, he wouldn’t have lasted very long at all.
Finally, as previously mentioned, you must not be a Muggle. More precisely, you must have magic in your blood. What is the point of attending a wizardry school if you can’t manipulate magic? The opposite applies as well. Attending a Muggle school never worked out so well for Harry Potter; it is unlikely that you will have much better luck yourself.
