This is mainly a psychological problem in the exam. Some children are not suitable for exams and usually do well. As soon as the exam comes, they don't perform well. In fact, this aspect also needs constant training. We should strengthen our confidence and believe in ourselves. If we study hard and accumulate well at ordinary times, we will certainly do well in the exam. Relax before the exam, give yourself more positive hints, and don't strengthen yourself too much, thinking that you may not do well in the exam. Don't have too many distractions when you enter the examination room, but concentrate on the exam. I believe that after several adjustments, you will definitely achieve satisfactory results in the exam!
