That makes sense, but if you are a good kid and usually do your work, most teachers will just give you a warning and assign you ASI if it happens again.

Yes, if you are assigned a paper to complete and you fail to do so, you should be punished. Teachers do a good job of reminding you when a paper is due and how to complete it, so there is no reason it shouldn't be completed. Even though in ASI, mostly just sit there, you are being punished which will help you to learn your lesson and not make that mistake again.
