When taking a quiz or an exam there are guidelines that each student should follow. No talking to other students near you. Only scratch paper, pencils, eraser, and calculator should be on the student's desk. They should not get out of their seats and come to me. A student should not talk to others around them because it might disturb those still taking the assessment.
Students can use the restroom if they are done.
This is by permission only by me. When I want the class's attention, there should be no talking and everyone should be focused on what I am saying. Trying to get my attention verbally, especially during lecture, will get no response and will be considered an interuption that is unneccessary. During warm-up activities. Before class has started.
