You have this idea to show that you want to study hard at university and enrich yourself, but I am clear on two points here: 1. Not having a mobile phone does not mean that you will not be distracted by other things. 2. Not all what the mobile phone brings us. The harm even said that mobile phones are very useful in class (seems nonsense haha). The first point: even if you don’t bring a mobile phone, can you let the roommate next to you not bring it? Obviously impossible. I once turned off my mobile phone without charging, and then I listened to the class for an hour and a half. No, no, I watched my roommate play games for an hour and a half. Not to mention that you have more common options like chatting with classmates and playing chess with Zhou Gong. The second point: if you get up late, you can only sit in the back seat because of reflections or there is a tall classmate in front of you. You may not be able to see the entire content of the blackboard all the time. At this time, you will miss your mobile phone camera. Even if you are sitting in the first row, there are always times when you feel important ppts are not copied in a hurry, right? Not to mention that some teachers in some schools will ask students to sign in with a certain APP before class. In summary, not having a mobile phone may not necessarily improve class efficiency. So what to do, you must sit in the front row! Best to sit in the first row! Put your phone on a prominent position on the table so that the teacher can see every movement of you. Sometimes you may feel that there are no seats in the front row, but if you look closely, there are usually 6 seats with 5 people in the middle. One is empty because the people on both sides don’t know each other. Then you just say: “Sorry, there is someone in the middle. “Don’t be afraid of embarrassment! What can be embarrassing about learning! Let’s stop here. I don’t know if you can see it. If it’s helpful, please comment and thank you. I’m pretty careful.
