15 questions for the genuinely well-read. Unusual flags, obscure capitals, precise science and fine historical detail. Very few people score 15/15 here.
Non-rectangular flags, Kazakhstan's capital, the most abundant elements, ancient treaties... This quiz does not forgive approximations. Only the genuinely well-read will score high.
This hard quiz is for people who have built real general knowledge over years of reading and curiosity. No trick questions — just precise knowledge that separates "I think I know" from "I actually know".
If you score high here, your general knowledge is genuinely impressive. If this level beats you, the Medium quiz is the right place to build up.
