上机考试重点考察考生的基本操作能力和程序编写能力，要求考生具有综合运用基础知识进行实际操作的能力。上机试题综合性强、难度较大。上机考试的评分是以机评为主，人工复查为辅的。机评当然不存在公正性的问题，但却存在呆板的问题，有时还可能因为出题者考虑不周出现错评的情况。考生做题时不充分考虑到这些情况，就有可能吃亏。(In the test, the basic operation ability and the program writing ability of the examinee are focused on, and the examinee has the ability to use the basic knowledge to carry out the actual operation. The test questions on the machine are comprehensive and difficult. The score of the test on the plane is based on the machine evaluation, and the manual reexamination is supplemented. Of course, there is no problem of impartiality, but there is a stiff problem, and sometimes the wrong comment may occur because the subject of the problem is not considered. If the examinees do not fully consider these situations when they do the questions, they may lose their losses.)
