You are taking other courses, probably are working over twenty hours a week, and you have fairly extensive family and social responsibilities. Moreover it is summer. Nonetheless, this is a college course and you are expected to invest at least 3 hours in study for every hour of class. Regular attendance is critical. Class lectures provide the critical theoretical context for your learning an class discussion is essential for clarifying your ideas and resolving doubts.
Classes are organic entities and easily disrupted.
It is important that your personal schedule permit you to regularly arrive on time and stay the full time. Such behavior not only hinders your own learning but prejudices that of fellow students. If that occurs quietly asks those responsible for the distractions to stop. If that fails to resolve the problem, plesae let me know. Every student has the right to learn as well as the responsibility not to deprive others of their right to learn.
