The first visit to the third grade is also called the "senior high school entrance examination". The first diagnosis and evaluation of most schools in Chengdu is basically at the end of the third semester. The performance of a clinic largely determines whether students can get direct and quota places to go to school.

It is also the main basis for signing a contract with a heavy high school. In addition, the difficulty and assessment scope of the initial examination are close to those of the senior high school entrance examination, so this examination is also an important basis for students to check and fill gaps in the review process.

There are several concepts that must be known about marker diagnosis: total score of diagnosis, high line, low line and effective score.

1, the total score of the initial test: 570 points: Chinese 150+ mathematics 150+ English 150+ physics (after conversion) 70 points+chemistry (after conversion) 50 points;

2, high line: that is, the key line, the difficulty of the test questions in each district is different, so the calculated key line is different (this line is also the reference line of high school and high school in each district);

3, low line: generally high line;

4. Effective score line: the minimum admission score line defined by the policy (note: the high-speed line in Wuhou District and High-tech Zone is the 479 middle admission line, and the low line is the key line).

In preparing for the exam, in addition to consolidating the knowledge reserve and knowledge system, it is more important to learn to adjust the mentality, make up for the loopholes through each exam, and avoid falling into the sea of questions and excessive pressure; Improving efficiency is king.
