The official document learning method does not determine the learning content according to the academic year of students, but evaluates the students' actual learning ability through the diagnostic test of academic ability, and finds the breakthrough point for students to learn easily. Because the content of the textbook is in line with students' own abilities, students can study smoothly and get 100 easily, thus gradually building up their self-confidence in learning and realizing the fun of learning.

Official documents have a standard completion time. Children and students in the lower grades of primary school study 10-20 minutes every day, and children in the upper grades study for 20-30 minutes, six days a week. Because children are required to finish their studies in a short time, they have a strong sense of time and the ability to concentrate their thoughts.

The arrangement of teaching materials of official document learning method is scientific and refined, which is convenient for students to learn quickly. Even if the starting point of learning is one or two academic years lower than the actual academic year of students, they can quickly catch up with and surpass the progress of the school within six months to one year, and reach the learning state beyond the academic year.
