It would be nice if last names were accepted. For example, I put professor Sprout for head of Hufflepuff, and it was not accepted so I thought I had it wrong. I didn't realize that it was necessary to type first and last names. If you want to leave it so it is required to type the full name, you should really put it in the directions since most quizzes accept just last names. It's a good quiz though. Thanks.
I get that the point of putting the first name is to make it harder, but they should clarify in the question that they want the full name. I wasted time putting on different answers until I said ‘Pomona Sprout’. And it’s inconsistent to want the the whole name there, and then have the name of Tonks’ dad to be ‘Ted Tonks’, when his name is Theodore.
