When deciding what level for questions at Mathopolis, I currently have:
Years 3, 4, 5, 6, 7, 8, "9-12", and University
But I would prefer to have:
Years 3, 4, 5, 6, 7, 8, "9-12 (General)", and "Advanced High School / Early University"
But that is just way too many words ... any suggestions?

The one that is there already is less words. What is wrong with the one with more words?
Maybe you might consider not rating them at all. It is therapeutic and humbling to work on a problem you have no chance of solving. Or it could turn a person into a serial killer... Maybe it is better to label them? Use the new titles.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Would a shortened form of "Advanced / University " do the trick ?
A user won't know if there is a page on the topic they want anyway until they try it, but it helps to narrow the search.
In the US and in the UK, "Advanced" seems to give the right impression about the level of the topic.
