Mathematical examples of college entrance examination
When we do math problems or simulation problems in the college entrance examination, we often encounter such a situation, that is, a question not only has a standard answer, but even a question has two or three answers. Here is a very simple example. For example, ask a question that x is a real number and satisfies the equation X 2 = 1 What is X? In this case, the answer is+1 or-1. If the examinee only works out one answer, should he give half a mark or not give it when correcting the paper?

It can be clearly told here that if there is no problem with the topic itself, the marking rules of the college entrance examination fill-in-the-blank questions will only be given points if they are all written correctly. If a situation is missing or unresolved, it is 0. There is no such thing as writing only one situation for half a point. Similar to the above question x 2 = 1, only? 1 Full marks will be given only when all situations are considered, and no score will be given if one situation is missing. Let's take this year's Jiangsu volume as an example. The question 13 in the above picture is 18/5 or 0 in the official standard answer. Notice here? Or? I don't mean to write any answer, but I mean to write two answers. So, if the candidate only writes a 18/5 when marking the paper, it is zero, and only writes a 0, which is also zero, but at the same time? 18/5 or 0? This kind of answer can get these 5 points.

The above are the marking rules for fill-in-the-blank questions, but if it is a big question, the marking rules are different. The marking rule of the college entrance examination is to give points by stepping on points, to add points if you write correctly, and not to deduct points if you write wrongly. Especially for liberal arts papers, a common saying of high school teachers is to write as much as possible, and don't leave blank questions that you can't do. You don't necessarily get points if you write, and you don't get points if you don't write. Mathematics in the college entrance examination often encounters classified discussions, such as the following math problem.

This problem need not be calculated. Let me tell you something. I asked about the value of the real number p. The topic itself is not very big, but it is relatively complicated to discuss. The first thing to consider is the case of p=0, and then consider p? 0, when P is not equal to 0, we have to do three tests: p=-2, p=- 1, p=2, and then continue to discuss P.

Topics discussed in this way appear in the comprehensive questions. As long as you write a situation correctly, you can get the corresponding score. If you write it correctly, you can get full marks. If you don't write completely, you can also get a correct score. So back to the question we discussed at the beginning, a fill-in-the-blank question has two or more answers. Missing or writing less is not half of the score, but no score. Although it feels a bit pitted, it is actually a way to judge papers. Candidates can only be more careful and considerate when doing the questions.
