According to the relevant regulations of the Guangdong Provincial Department of Education, students can choose to apply for 1 to at most 3 professional groups when filling in their volunteers. This means that each student can apply for up to three different major groups, which will increase their chances of entering their favorite major and provide students with more freedom of choice.

For the school, there is no clear stipulation that a student can apply for several professional groups. Each school will usually formulate corresponding enrollment policies according to its own situation and resource allocation. Generally speaking, according to the enrollment plan and enrollment situation of different professional groups, the school will ensure that suitable students are recruited to meet the needs of various majors.

Schools can also refer to the following factors when determining the number of professional groups that each student can apply for:

Major setting and resource allocation of schools: The major setting and resource allocation of different schools are different, and some schools may only provide limited choice of major groups.

Students' academic level and interest: The school may encourage students to choose suitable professional groups according to their academic level and interest, so as to improve the admission opportunities and meet the needs of personal development.

Enrollment plan and enrollment situation: according to the enrollment plan and enrollment situation of each professional group, the school can determine the number of professional groups that can apply for the exam to ensure the principle of fair and just admission.

It should be noted that each major group may have different examination subjects and admission criteria, and students need to understand and meet the corresponding requirements when choosing each major group. In addition, students should carefully choose professional groups according to their own situation, personal interests and future career plans to ensure the most suitable education and development opportunities.

In short, the number of professional groups that each school in Guangdong can apply for the new college entrance examination is not clearly defined, and the school will set corresponding restrictions according to the actual situation and enrollment policy. Students should choose the professional group reasonably according to their own situation and school requirements when filling in their volunteers, so as to lay a better foundation for future study and career development.
