There's always that one person who seems to be way more stressed than everyone else for exams and in turn stresses out everyone around them. The last thing you need before an exam is someone coming up to you and telling you how little they know when you yourself know nothing.

This person always ends up doing well in the exam in the end which is so annoying because they were telling you before how they knew 'nothing' when in fact they had spent hours revising the night before. If you knew stuff, why were you stressing?

This person can annoy me because they really stress me out before exams, and stress makes me forget everything I know (which usually isn't a lot lol).
