(1) First, do it on the draft paper, mark it with serial number, and come down in sequence. Don't make a draft casually. In this way, the idea may be confused because the draft paper is written at sixes and sevens, but it should be written neatly line by line (but neat handwriting is not required, as long as you don't misread the handwriting of your own words. For example, when you calculate, there is a reasoning here and a process there, and then it may take time to find the process).

(2) Practice writing speed. It may be that the writing speed is not fast enough, and you deliberately practice the cursive writing speed that you can see clearly (judging from your question with pen and ink, the typing speed should not be slow, and the slow typing speed usually slows down the writing speed: because typing and writing are not the same method by hand, for example, Jin Yong only typed when he wrote a novel, so he admitted that he wrote it with a pen).

(3) Now say one of the most critical methods:

Sometimes thinking inertia will lead to mistakes. If this mistake is only attributed to carelessness, it ignores something about your own psychological rhythm: for example, if you multiply A by B, one of them will be multiplied incorrectly for various reasons, or a trigonometric function will be called or a constant will be wrong at other times.

This is not only carelessness, but you may also find that you can't make a mistake only once, and you may be careless in a similar place next time.

Methods: When practicing at ordinary times, repeat the wrong questions every 15 minutes, 30 minutes, 2 hours, 8 hours, the next morning, at any time on the fourth day, and at any time on the tenth day. You may think, is it necessary to do a wrong question seven times and then do it at intervals?

It is necessary to:

I've done it seven times, and I pay attention to your possible mistakes every time to speed up my writing.

Don't worry, you have memorized the process and the answers. If you do the problem several times, you may make a mistake or the calculation format is inaccurate. This is a good time to correct mistakes.

(3) A college entrance examination champion made nine wrong questions and said that this method was very useful.

Why are you so concerned about this wrong question? Even if it is caused by carelessness. Carelessness can be found, although the reason seems to be the same: "carelessness", but there are different types of carelessness. Only by solving them one by one and summing up the places and times of carelessness can we remember our carelessness and make 100% correct.

④ It is also very important to adjust your usual practice speed:

1, don't worry when practicing at ordinary times: carelessness is caused by deliberate anxiety. The habit you usually form in a hurry will be taken to the examination room. If you are not careless when doing the problem, it is more meaningful than doing the 10 problem, because carelessness is a habit that can't be cultivated at ordinary times; Don't be afraid that this will slow down the speed of doing the problem. The speed of doing problems is not a habit in essence, but an ability. Only if every step is not sloppy and practical can we really control the speed at will.

Pay attention to your psychological state in the examination room, and don't be biased: think you will be careless. Face up to the exam. For the part that you may be careless, think back to the situation that you are often careless in practice and which arithmetic is easy to make mistakes, so that you can concentrate and be alert to that situation (for example, you can easily confuse some formulas and spend a few seconds reviewing those formulas).
