Of course, I have already done it. Before school started at that time, I went to a nearby university to attend classes, and the teacher would never recognize whether you were in that class or not. Of course, you'd better not go to that small class. There are few people and it's easy to be found. If the number exceeds 50, it is best. In short, go to class boldly as if you were from that school. Having said that, adopt it (* _ _ *)
