A: Students must abide by the "Regulations on the management of mobile phone use of students in grade 10 and grade 11" and "Regulations on the management of mobile phone use of students in senior 12".

The basic content is as follows: after the students arrive at school at 7:20 in the morning, the teacher takes over their mobile phones and lock them over to the safe. During class and self-study, students are not allowed to use mobile phones without the permission of the teacher. Once found, the teacher in charge of the class will confiscate them to the head teacher and punish them.

Grade 12 students need to complete a large number of paper reports, speeches, etc. In order to facilitate grade 12 students to consult materials and complete reports, they do not implement the mandatory mobile phone delivery policy. But they must also abide by the "management regulations" in the use of regulations.

Laptop: students in grade 10 and grade 11 are not allowed to take it; students in grade 12 should take it according to the actual situation.
