1, the course is different from CET-4: the teaching of Class A students starts from the second volume of New College English, and CET-4 is allowed in the second semester. Starting from the next semester of the second academic year, advanced English elective courses or specialized English courses will be offered. Missing credits can be obtained by taking "extended courses" Students who pass CET-6 can get credits directly without taking college English test, and the scores of courses without classes are recorded according to the grade points of 85 points and 3.5 points.

Class B students began to learn from the first volume of the textbook, passed the course of 1-4, and obtained the required 12 credits. Students can also take "expansion courses" voluntarily, and the credits are determined according to the public elective courses.

2. The reform of teaching methods and teaching means is different: Class A adopts the "2+ 1" curriculum mode, while Class B can focus on classroom teaching, combined with classroom interaction, and the online autonomous learning platform is open to students.
