Looking at the inner volume from the difference of scores
? Answer: As long as you get 90% of the papers correctly, you will get an A.

? B: A test paper with a score of 10% will be given to A.

? If you were a candidate, which exam would you rather take? Answer? Or b?

? Maybe some people haven't seen the difference between the two. The goal of A-level candidates is mastery rate. As long as you can reach 90% of the test paper, you can get a and b papers, which is different. If you meet a master, you may get 95 points, but you may not get an A, just like primary school students now. It is said that some students in the class scored between 90 and 95 points, which is the bottom of the class. Under pressure, teachers and parents are anxious, and extra homework or make up lessons destroys the flowers of the motherland.

? The Alevel exam that we are familiar with is a kind of exam, and you can get an A if you get more than 80 points. On the other hand, almost all kinds of domestic exams are B-type exams. In particular, some minor courses that are not included in the total admission score also adopt the principle of Grade B, which I think is really unnecessary. The disadvantages of the second exam are obvious. First, it is easy to cause involution. The first 10% is finite and fixed. For this 10%, it leads to disorderly competition. Assuming that the topic of an exam is simple, more than 10% of the candidates get 100. The question is coming, how to give points? Who gets on and who gets off? In order to avoid this phenomenon, should the next proposition be a little more difficult? This phenomenon, like our present objective reality, is far more difficult than the textbook requires.

? The difference of A-type examination is that the examinee does not need to compare with others, and his goal is to meet the requirements of teaching objectives. For example, the teaching goal of mathematics in the first semester of primary school grade one is to master the addition and subtraction of 1-20. As long as the child can get 90% of the total score of the paper, he can get an A, and there is no need for an inner paper.

? Thoughtful readers may notice that if 100 students enroll, what will happen if more than 100 students get an A? Many countries in Europe and America give schools greater autonomy in enrollment, and each school chooses students according to its own training objectives. So you can see that in addition to academic qualifications, admissions officers also pay special attention to other supporting materials of candidates. On the one hand, this diversified evaluation standard reduces the pressure brought by a single evaluation standard, on the other hand, it also promotes the diversified development of candidates.

? The result of domestic internal examination papers is that they care too much about scores, because every big exam in life uses scores to measure candidates and score students' life roots. In American exams, students will be evaluated in many aspects besides their academic performance. For example, everyone's academic performance is the same, and their critical thinking ability, sports ability, organization and management ability, charity and so on will be compared. In other words, there is involution in education at home and abroad, but we only pay attention to grades at the expense of children's physical and mental health in the process of involution. In the United States, it involves investment outside of study. Besides grades, we also pay attention to students' all-round development.
