Your character is too worried and hesitant about things, worrying that something bad will happen. Because you are a student, the exam is very important to you, so the problem is highlighted. In fact, everyone is worried about important things. Do your best. I once had the same question. Even more exaggerated, I will solve the same problem in different ways to determine my answer. I am also worried, so I said to myself, no matter what the problem is, I will only do it once, but I will try my best to take it seriously during this time. Even if I make a mistake, I will admit it and do my best to have no regrets. After repeated inspections, it was found that the error rate did not increase. Have a positive attitude, and don't always think of the bad. You are so cautious, you can develop in the direction of research in the future. I wish you success in the college entrance examination! !
