What does the "3+2+ 1" model mean in the comprehensive reform of college entrance examination?

Remember the college entrance examination?

At that time, we took the college entrance examination, which was simple and rude. It is divided into liberal arts and science, and each subject has six courses.

In addition to the number of languages that everyone has to take, the other three subjects that liberal arts students need to take are politics, history and geography, which is called comprehensive literature for short.

Science students need to take physical chemistry and biology exams.

When we finished the exam, a reform came. At that time, it was rumored that high school was divided into arts and sciences! Then, in the spring breeze of reform, we ushered in the 3+3 model.

The first three still refer to the number of words, and the last three refer to choosing three from six courses (politics, history, geography and biochemistry).

This gives candidates great freedom of combination. According to the principle of permutation and combination, I will count with my fingers. My god, there are 20 combinations for you to choose from.

Soon, the drawbacks of this system were exposed.

Many people choose simple geography, and physics has become a neglected subject because it is difficult! But this will not work. Students from all over the country have gone to study geography. Who can learn physics?

Among various suggestions, we have ushered in the spring breeze of reform, which is exactly the 3+2+ 1 model we are seeing now.

Similarly, the first 3 is still beyond the number of words, but the last 3 is broken down into 2+ 1.

2 means to choose politics, geography, chemistry and biology, 1 means to choose physics and history, so each candidate's choice is reduced to 12.

Statistics show that in the scheme of 3+2+ 1, the proportion of reportable majors in the combination mode of physics+chemistry+geography reaches 99.4%, and the compulsory choice between physics and history also prevents candidates from choosing some unreasonable combinations.

Such as history+politics+geography, or physics+chemistry+history.

Generally speaking, the model of 3+2+ 1 still has some advantages over 3+3, but different provinces have different choices, such as Shandong Province, which has not changed with the wind and still adopts the model of 3+3.
