I think it's better to have classes at school, which has a sense of atmosphere. Few people are so self-disciplined. People are a group, and it is natural for animals to socialize.

Every student and educational environment is unique, so which method is more effective may vary according to individual circumstances.

Advantages of online courses:

1. Flexibility: Online courses can be arranged according to students' time schedule and personal needs. Students can learn at their own pace and have more opportunities for self-control.

2. Accessibility: Online courses allow students to obtain educational resources no matter where they are. This is especially important for students with remote geographical location or mobility difficulties.

3. Diversified learning resources: Online courses usually provide a variety of learning resources, such as online lectures, teaching videos, interactive simulations, etc. This diversity can satisfy students with different learning styles and interests.

Advantages of attending classes at school:

1. Real-time interaction: Face-to-face real-time interaction is provided in school classes, and students can communicate, discuss and ask questions directly with teachers and classmates. This kind of interaction helps to deepen understanding and strengthen learning.

2. Social and cooperative opportunities: attending classes at school provides opportunities to interact with classmates, establish social relations, carry out cooperative learning and team activities. This is very important for the development of students and the cultivation of interpersonal relationships.

3. Discipline and time management: Students are required to observe the timetable and discipline in class, and cultivate their self-discipline and time management ability.
