I can’t not comment on this. I have a username to live up to!
I’m gonna be brutally honest here by saying that a Sorting Hat quiz is in no way an original idea, but I guess it’s cool that you wanna try and use ChoiceScript to make it. The thing is, if you’re only going for a system this simplistic, it’ll be a regrettable waste of an awesome programming language. Why not expand? I see that some of the questions are lightly roleplay-based, maybe you could make the whole course of the quiz a string of roleplays that come together as a short story. Y’know, like a Choice of Games game. Maybe you can even make some sort of character customisation, even a very basic one. In my head, I imagine it can be something like the Hosted Game Dilemma. It doesn’t have to be set in the HP universe, though occasional references could certainly help set the mood.
Speaking of mood – the whole quiz does not at all have any HP feel to it aside from the fact that it’s a Hogwarts house quiz. With what you have so far, the quiz has certainly reached its goal in being a Sorting quiz, but that’s all there is to it. If you do insist on sticking to what you have, maybe you can make some small modifications to give the quiz more HP flavour. For example, the line, “You just found some money on the ground,” could be altered to, “You just found a few Knuts/Sickles/Galleons on the ground.” Another example, “Exams are coming up,” could be changed to “OWLs/NEWTs are coming up.”
I realise this is supposed to be a quick Hogwarts house quiz, so feel free to ignore my suggestions if the kind of game I’m suggesting is not the one you’re trying to make, in which case I can only advise brushing up on your knowledge of the houses. To be honest, there are some choices whose results (to the “house points”) I don’t completely understand, but then again Sorting is a very relative and subjective matter. I recommend looking up the official Pottermore Sorting Hat quiz for the most accurate reference you could possibly get. I haven’t looked for any detailed breakdown of the quiz, but I do know that there are transcripts available around the internet and that unofficial (though identical) versions of the quiz are available outside of Pottermore.
Also, typo spotted.
Try and find out who’s it is.
It should be whose instead of who’s.
And, oh! Since “Adding a fancier way of saying your final house” is on your list, I have an idea that ties into my other idea about making the quiz a short story-game. I mentioned that it didn’t have to be set in the HP universe but also that references would be appreciated, especially by the Potterhead CoG-ers out there (like moi!). I imagine the MC going through a day no different than any other (the day being the story in which the player makes their choices), just doing what they do, but at the end of it discovers OMG IT’S THE SORTING HAT FROM HARRY POTTER and puts it on. The Hat then voices its thoughts about the MC’s personality before declaring their house (a la canon Hogwarts Sorting Ceremony). MC contemplates how they feel about it, calls it a day, and THE END! The Hat may or may not be a figment of their imagination. XD
Again, feel free to dismiss this notion if the idea of making the quiz into a story does not suit your purposes.
Best of luck.

EDIT: @Uniqueth Thanks for linking it! That kind of quizzes is the one I was talking about.
I would add in something about Choice Script, but that’s kinda implied.
