It does specifically say that you shouldn’t put it up for the general public if it is a specific subject and not general knowledge. What have you done? It says that the group with maths, science, physics and spanish in (Español has a ñ) is places, which is wrong, the same as the one that is places. The groupings are far too general, and therefore difficult to get, even if you get them right, with the exception of seasons. The fact that boxes with question marks appear instead of accents makes this infuriating. I got an A* in my Spanish GCSE and I got 6 in this because it wouldn’t accept my links.

TL;DR
It isn’t general knowledge
There are mistakes
Accents don’t appear
It’s not “very easy”

I’m sorry to be so negative, but there isn’t much good to point out.
