1, admission time is different. The time for class A admission is generally within two weeks after the results of the college entrance examination are announced, and class B admission is about one month after the end of class A admission. Therefore, the waiting time for class B candidates is longer.

2. The admission criteria are different. The standard of class A admission is relatively high, which generally requires excellent results in the college entrance examination and outstanding comprehensive quality. Class B admission is relatively loose, and some colleges and universities will even relax the admission criteria to recruit more students. Therefore, candidates who are admitted to Class B have a greater chance of admission.

3. The number of admissions is different. Due to the high admission standard of Class A, the number of students enrolled is relatively small, while the admission standard of Class B is relatively loose and the number of students enrolled is relatively large. Therefore, candidates can choose which batch of admission to participate in according to their actual situation.

4. The admission major is different. Due to the higher admission standards of Class A, the majors admitted are relatively more popular, such as medicine and engineering. Class B admission is relatively relaxed, with a wider range of majors, including some less popular majors.

Matters needing attention in choosing a university:

1. Choose a field consistent with future employment.

When students choose a university, they must first determine whether the area they choose is south or north, inside or outside the province. Students should try to choose a suitable area for employment after graduation, and it is more convenient to stay in this area directly after graduation.

2. Choose a major that suits you.

It is also very important to choose a major in a university, so when choosing a university, students should find out whether the university has a satisfactory and suitable major. Whether there is a good major is also an important basis for students to choose a university, which needs detailed investigation.

3. Clarify the admission rules of colleges and universities.

When choosing a university, you should carefully read the university's enrollment regulations and make clear the admission rules of the university, such as parallel volunteer admission, preferred admission, admission conditions and requirements.

4, understand the specific situation of colleges and universities.

Students can log in to official website, that is, register colleges and universities, inquire about the specific situation of colleges and universities, and also learn about the development history, number of students and teaching quality of colleges and universities through other channels.
