First, we need to understand this model. The new college entrance examination "3+ 1+2" mode breaks the traditional division of arts and sciences. High school students can freely choose their own subjects of interest, fully tap their potential and stimulate their potential. The new college entrance examination is also very good for students' future career development. It is divided into the following three parts.

The first method is subtraction. As we all know, there are 12 subject combinations in the "3+ 1+2" model of the new college entrance examination, such as "materialized life", "material life", "calendar place" and "calendar biochemistry". The learning difficulty of each subject combination is different, and it seems more troublesome to choose subjects. The so-called "subtraction" course selection means that we have to choose one of the two compulsory subjects of physics and history. Once one of them is determined, the curriculum combination will be reduced from 12 to six, and it will be easier for us to choose a subject, while it will be easier to choose a subject of physics or history, because choosing a subject of physics is equivalent to choosing "science" and choosing a subject of history is equivalent to choosing "liberal arts".

The second method: choose subjects with "grades". Choosing subjects based on "academic performance" is the most direct and rude method, which is faster and easier. The subjects of "3+ 1+2" in the new college entrance examination are generally selected at the beginning of the next semester of senior one or at the end of the first semester of senior one, when students enter the second year of senior two. At this time, after half a year or a year's high school study, students have a certain understanding of all subjects, and clearly realized their own advantages, and passed many exams, and they are very clear about which subjects have good grades and which subjects have poor grades.
