Earn up to four credits in just three weeks

Cornell's Winter Session features online and off-campus courses taught by outstanding Cornell University faculty members. Enrollment is open to all—from undergrads and high school students to alumni and any interested adult.

Winter Session is ideal for students wishing to earn credits before the spring semester, catch up or get ahead in their studies, and really get to know their professors.

In just three weeks you can fulfill a requirement, complete a minor or double major, take a course not offered during another semester, explore an academic field, and/or focus intensely on one subject, without distractions.

You may choose from online courses as well as domestic and international off-campus courses.

Areas of study range from the arts and business to the sciences.

Please confirm class dates on the class roster or your class syllabus. Final exams will be held on the last day of class, Friday, January 17, unless otherwise noted by the class instructor in the class syllabus. (Winter Session last ran this way in 2016.)
