Write completely and clearly
For the calculation questions on the test paper, pay attention to writing completely and clearly, so that even if one calculation value is wrong, it will be clear in the whole problem-solving step, and you will get the corresponding score. Even if the calculation problem is simple, write a detailed calculation process and try to be accurate.
Understand the problem carefully
In multiple-choice questions, the answer you calculated may be different from the answer selected by the line. This is to look at the topic carefully. Perhaps the topic requirement is to choose the closest one, so we'd better examine the topic carefully before answering it to save time.
I remember every formula clearly.
We should also pay attention to the selection of various parameters in the process of doing calculation problems. If there is a mistake, it may lead to an error in the whole calculation process, so you should remember each formula clearly in the preparation for the exam on weekdays and don't confuse it.
Read the known conditions carefully
We must read the conditions given carefully. Some unknown conditions can be derived from known conditions, and some questions will give some hints, so be careful not to ignore them, which may be used in the process of answering questions.
Multi-condition control
In the process of calculation, we must also pay attention to multi-condition control. Some topics require us to get a numerical value through calculation, and then take a larger value or a smaller value. Judging from the test results in previous years, except for one answer, many candidates made hasty choices, which led to the wrong answer.
