Generally speaking, most public colleges and universities allow students to take photos with their mobile phones in class, because it is convenient and fast, and teachers don't have to stop to wait for students to take notes in class, which improves the efficiency of class. And many times you don't need to take pictures with your mobile phone. After class, most of the learning members in the class will ask the teacher for the PPT used in class, and then send the PPT file directly to the WeChat group in the class for everyone to take notes or review the class content.

Private colleges and universities generally accept mobile phones in the name of strengthening management, and students are not allowed to use mobile phones in class.
