Undergraduate students enrolled in courses with in-person class meetings are expected to be on campus and in attendance at the start of classes and must plan to remain until the end of the quarter.  Note in some cases, students must attend the first-class meeting to avoid being dropped. This will be clearly identified in CAESAR and the syllabus. Read the full policy: https://www.northwestern.edu/provost/policies-procedures/classwork-curricular-policies/in-person-arrival.html
