Under normal circumstances, you should try your best to assign classes to several students who are close to each other, because there will be no good seats in the front row if you don't go to the classroom half an hour before the university class begins. You can take a seat by one or two people at a time, preferably two people, so that you can put some schoolbags and books on both sides of the seat you want to occupy, and basically no one will take the initiative to ask if there is anyone here. That's how I came from college.
