First of all, I think people are prone to make such mistakes when they are very tired. So whether the landlord can avoid fatigue now or not, you must have a good rest in those days of the college entrance examination, otherwise it will be troublesome to bring this into the college entrance examination room.

Second, you can try to take your usual homework as an exam and set your own time. This is my own method, which may not work in a short time, but I think it is very effective to stick to it for a month or two to avoid careless mistakes.

Third, you can write tips for yourself in the examination room. Just write a note and put it in your pocket. Take a look before the exam. It talks about where you are prone to make mistakes, and some sentences attract your attention (no matter how irregular the mistakes are, nonsense always has a certain tendency, I think, for example, you can always copy C into D, so you can remind yourself). I used this method, too.

Fourth, you can look back in the examination room. After reading a question, you can go back and scan it again. It takes about a second to scan. Often this can correct the mistakes in reading questions, which my grandfather used to emphasize to me. Also, I think some students underline the key points of the topic (such as data, yes, no, correct and incorrect keywords). You can also try.

The most important thing is to calm down! Don't be nervous because you don't attend class, because you always make mistakes. You should firmly believe that all this can be avoided by having a good rest in those days of the college entrance examination.
