We don't know what to bring. But I'm in high school now, and I also took an examination of computer operation. It won't be difficult. They are all simple questions. And our teacher will tell us how to take the exam, so you don't have to worry too much.
What should be paid attention to, the teacher should say it, but you should remember, when taking the exam, ask the teacher if it's okay! Be sure to remember that you can't just ask if you can, but your classmates and teachers can. We were like that. I don't know if you can! I wish you a smooth pass.
