Infinite: If You Fail, You Will Die.

When I was in school, the most I could get was a scolding from my parents if I failed the exam. But if I failed the exam here, I would die... Sleeping with a monster female corpse in a terrifying dungeon, being hunted by a demon hunter on an island in another world, overthrowing the Empress of the Three Kingdoms in the underground world... Abnormal passing conditions, eternal punishment for failure, all just for that damn diploma! This novel and its characters are purely fictitious.
