You're expected to attend all courses in which you are enrolled and to do so regularly and punctually.
Please remember that the content of Cornell's three- and six-week summer courses, and three-week winter courses, is equivalent to that of courses offered during the university’s 15-week fall or spring semesters. Thus, missing any class time during the summer or winter will put you in serious academic jeopardy.
If you miss a class, it is your obligation to let the instructor know why, to provide documentation that you were seen at Cornell Health or another health care facility, and to keep up with the coursework.
Students who miss two or more days of class for any reason, who do not complete assignments, or who are disruptive in any way in the classroom may be dismissed from the program.
