Which KHS teacher would be your best friend? After you take this quiz there is no turning back. The next time you see your btf (best teacher friend) in the hall you will be compelled to give them a fist bump, high five or simple hello. Beware, for you will probably want to repeatedly take it to see the different teachers you can get matched up with but after truthfully taking the quiz for the first time that teacher will be deemed your best friend. The quiz has spoken.
