I had trouble with exams and not turning in homework in math class in 10th grade. The teacher would keep pressuring me to ask questions when it’s obvious I wasn’t paying attention. One time I caved in and proceeded to blurt out a disjointed stuttery mess of a question that took 30 seconds to get the point across. Needless to say, she never bothered me again. I’ve since come to term with my problem and made some effort to quell it. So far, it’s going decently.
