As a boost to A-level students, the London Dungeon and its locations in York and Blackpool gave free entry to students who attained a grade D or below in history.

If the students took proof of their failed grades to the attraction, they were granted entry for free so that they could learn about "the dark, uncensored history that went over their heads the first time," said Dungeons in a press release.

Said the operator: “There are scarier things in life than short-term exam result setbacks and we don‘t want to let that kill your summer vibe, so this year we are celebrating those who got horrendous history results and turning those rotten exam papers into a golden ticket.

"Those disappointed with exam performance can instead get a gruesome (and more interesting) history lesson with a difference and swot up on the knowledge they missed the first time.”

Dungeons are operated by Merlin Entertainments.
