I have changed KL and LA. I think I once played a quiz where they were accepted and that's why I included them.
I was going to do a quiz like this, but the other way round: the long-form is given and you have to type the type-in. It would be easier of course, but I imagined it as a "tutorial" for people who weren't aware of them. I'll leave it for you if you want to go for it though since you had the idea first.
BTW, you could/should add DPRK and ROK - very common and useful type-ins!
Nice work ;)
Also, thanks for the quiz idea, and the new inclusions for this quiz which I've added!
Thanks again for the idea!
Hope they can help you in the future.
