Dom opened up about his time in high school when he was going through his NCEA exams. It was one of the most stressful times of his life. He would try his best but in the end school wasn't really his thing.
If you are no good at exams and are worried about how things are, it's not gonna be the end of the world... there are so many more sparts that matter in the adult world.
Good luck with your exams. But just remember it's not the end of the world.
