What kind of experience is it to be scolded by the teacher before the paper is finished?
Sometimes the teacher scolds you for not finishing the paper. First, you are angry, then you are sad. More often, it is a kind of self-reproach. Because you didn't finish the paper, many reasons are that you were too lazy to complete the 20-minute task set by the teacher, so you will feel inferior that you didn't study hard to complete the task.
