How do you tell what class you are and if youre a derse or prospit?

For deciding my classpect I just read about them and after some self analysis I determine which suits me best. I know there are some quizes out their that you can take but I prefer to do it myself.  As for Derse and Prospit. For the kids it was those with a messy bed were on Derse and those that made their bed were on Prospit, but that doesn’t seem very reliable. I’m sure there are some quizes for that out their too.
