You can not choose the HOL House you want to be in, the HOL Sorting Hat is telling you what house you belong to. You need the HOL-Name you have registered with, please spell it correctly or your Sorting will not work! You must have passed the Entry Exam first. You have just one try, only the first Sorting counts! If you put on the Sorting Hat more than once, you won't get any results as your name has been removed from the "Sorting Hat list" already. Please take your time to answer the Sorting Hat's questions, and do not forget... hit the final button just ONCE!
The Sorting Hat is nothing to play around with. As it automatically generates Student Files, it is also NOT possible for any old students to 'try out' where they would be sorted into now.
