The school wants the wrong book and wants to buy the wrong printer. Is it useful?
I think the wrong printer is useful and has the following advantages:

1, easy to use and efficient. The misprinting machine, also known as pocket printer, is small in size and easy to carry. The biggest advantage of misprinting printer is convenience and high efficiency. If you have a wrong topic, you can take a photo directly and print it out, but at present, the printer needs to be connected to a mobile phone, so it is very inconvenient to use it in schools without mobile phones.

But if you have a mobile phone, the wrong question printer can save a lot of time to extract and sort out the wrong questions, and students can focus most of their energy on copying knowledge points. I often use the wrong printer to see topics that I think are good, take this photo, print it out and put it in the wrong topic set, and browse it from time to time to consolidate the knowledge points. I find it very convenient.

2. Wrong printer and wrong layout. With the wrong printer, you should be able to use it correctly.

1) resist the temptation and arrange the use reasonably. The wrong printer needs to use the mobile app. Many people unconsciously drive Tik Tok aaauto faster when they pick up their mobile phones, and forget to sort out the wrong things. Therefore, when using the wrong printer, they should avoid being influenced by the mobile phone.

2) Treat the wrong questions correctly. Some students corrected the wrong questions in order to correct them. With the printer, they blindly pursue the quantity of correcting the wrong questions and ignore the quality of the wrong questions. The original intention of correcting the wrong questions is to come back regularly to review your wrong questions and then consolidate them in time. Therefore, the wrong printer is used, and we should pay attention to the quality of the wrong questions while improving the quantity.

3) Don't rely too much on the wrong printer. Although it is convenient to use the wrong printer, we should not rely too much on using the wrong printer, because some topics are classic and even the stems of the topics are full of knowledge points. At this time, if you can extract the topic once, it is learning. So when using the wrong printer, don't rely too much, and grasp the opportunity to use it.

These are some of my views and opinions. If you have any other opinions, welcome to exchange and discuss in the comment area!
