Sure. One 'A level horror story' could be about a student who was studying alone at night for an A - level exam. Suddenly, the lights started flickering and they heard strange scratching noises from the walls. As they looked up, they saw a shadowy figure slowly approaching. It turned out to be their over - stressed mind playing tricks, but it was terrifying at that moment.
Well, here's another. In an old school building where A - level classes were held, there was a rumor of a ghost of a former student who had failed miserably. One day during an exam, a student noticed that their pen was writing by itself. The words it wrote were full of despair and failure, as if the ghost was trying to relive its own experience through the student. Eventually, the student realized it was a prank by a classmate with a magnetic device, but it gave them a good scare.
