Classes in universities are generally large classes. As long as it doesn't violate discipline, it's generally fine. It's okay to put the computer in the bag. Of course, if you use it, it is estimated that the teacher will take care of you. When you use your laptop in college, you should put it away. Don't put it on the desk, try to lock it in the cupboard and pay attention to closing the doors and windows. Generally, you don't need to put too much cash on you. One or two hundred is enough, so you don't have much anti-theft knowledge. Just pay attention to yourself. Don't always put the computer on the desk. People can steal as soon as they come in. The most important thing is to lock the doors and windows. Thank you!
