If the test questions are difficult enough and the average score is only 50 points, a single subject with a score of 100 can establish an advantage of 50 points over all other students, and if the second place is only 90 points, it can also establish an advantage of at least 10 points or more for anyone.
But for the same difficulty, if the score is assigned, 100 points are still assigned to 100 points, and the score of 50 points may be assigned to 75 points, so that the average advantage is reduced from 50 points to 25 points, and the 90 points of the second place can also be assigned to 99 points or 100 points, and there is almost no difference.
Although between students at different levels, the disciplines assigned to the score can also establish advantages, but for the same level of level, the gap is not obvious, the ranking difference between the ordinary excellent students 80 points, and the middle students test 70 points, is far greater than the difference between 90 points and 80 points.
The higher the grades, the greater the difficulty, and the lower the corresponding input-output ratio.
A real scholar can often establish an absolute advantage in foreign language, mathematics, and foreign objects, while chemistry and biology only need to establish a relative advantage, and even if there is no advantage, it does not have a big impact.
It is more common for many students with obvious advantages in language and mathematics to obtain a more obvious ranking improvement after being assigned.
