One of the students, speaking to newspaper The Tab, said:
"I raised my hand briefly, hoping to inform the invigilators of the error, but quickly retracted it after realising I might be the only one with the mark scheme."
On looking around, I heard one of my peers sniggering at the front of the exam hall, and then seconds later the whole hall was in stitches as our examiners looked on blankly. Surely the best start to any of my exams."
A red-faced convenor decided to remove the mark schemes from the test and give it back to students, hoping that they would not be able to remember most of the answers.
