Unless otherwise stated, all precollege classes are regular, credit-bearing Cornell undergraduate classes and must be taken for credit and letter grade only. You may not take courses on a pass/fail or satisfactory/unsatisfactory basis, except for Computer Science 1109. There is no audit option.
Before selecting your course, be sure you meet any prerequisites listed.
Note: You're required to remain enrolled in at least three credits for the duration of a three-week session and in at least five to eight credits for the duration of the six-week session.
Also, if you wish to take more than one course in a session, check the credit limits.
All class times listed are in Eastern Time.
Selecting online courses
Online courses are offered synchronously and/or asynchronously. To determine which method will be utilized, find your course on the roster and look for “instruction mode.”
Definitions of online instruction modes
- OL/Online Learning:
This course will be delivered completely online. Required class components (such as lectures, labs, discussions, etc.) may be delivered in pre-recorded (asynchronous) and/or live (synchronous) modes. For example, an instructor may provide pre-recorded lecture materials that you view on your own schedule but require that you attend live discussions at scheduled times. Note: You are expected to participate in live, prescheduled (synchronous) sessions as long as the scheduled meeting time is between 8:00 a.m. and 10:30 p.m. in your local time zone.
- AD/Distance Learning — Asynchronous:
This online course features well-designed, pre-recorded content that you may access at any time, on your own schedule. You interact with other students and the instructor via the Canvas online learning system, which may include email, online discussion boards, interactive chat rooms, and/or video conferences. Many instructors also offer online office hours.
- SD/Distance Learning — Synchronous:
This online course features well-designed content, live interactions, and required class components (such as lectures, labs, discussions, etc.) that you access at pre-scheduled times. For example, during a six-week summer class, your instructor might deliver lectures from 10:00–11:00 a.m. on Mondays–Fridays and hold discussions on Tuesdays and Thursdays from 1:00-2:15 p.m. These sessions will be delivered live via videoconferencing software (e.g., Zoom). Note: You are expected to participate in live, prescheduled (synchronous) sessions as long as the scheduled meeting time is between 8:00 a.m. and 10:30 p.m. in your local time zone.
- HY/Hybrid — Online and In Person:
This course combines in-person instruction during scheduled meeting times with synchronous online learning, using a rotational attendance model. For example, the class may be split in half or thirds and you alternate between participating in person and attending online at prescheduled times. Some in-person activity is required.

*Note for Fall/Spring students: You may request permission to enroll in courses at the 1,000 or 2,000 level as long as you meet the prerequisites listed for the courses on the precollege Fall and Spring online course pages. Note that Fall/Spring courses marked with a red square are full and not available for enrollment.
Selecting on-campus courses
You can filter this list by subject, session, eligibility, and more.
- Students in the three-week Summer Residential Program must select one three-week course.
- Students in the six-week Summer Residential Program must select two or three six-week courses.
Consider taking a Cornell first-year writing seminar.
Local students may take on-campus courses in the fall, spring, and summer.
Time in class
For each hour of lecture, you should plan on two to three hours of homework.
If you are taking a summer or winter course, this timing reflects the fact that you'll be completing an entire college semester in just a few weeks.
For example, if you take one three-credit, six-week class, you should plan to spend approximately 1.5 hours in class and up to three hours doing homework each day. If you take two three-credit, six-week classes, you should plan to spend approximately three hours in class and up to six hours doing homework each day.
Tips for selecting courses
- Cornell undergraduate courses are more difficult than high school or AP classes, so be prepared for a challenge.
- The content of three- and six-week summer courses, and three-week winter courses, is equivalent to that of courses offered during Cornell's fifteen-week fall or spring semesters, so you'll need to maintain an accelerated pace throughout.
- High school students in these courses are evaluated by the same academic standards and procedures as undergraduate students.
- Because our courses are regular Cornell undergraduate courses, your classes may include regular college students as well as other precollege students.
- When reviewing courses be sure that you are eligible and meet the prerequisites. We will contact you if, after reviewing your application, we have any concerns about your qualifications for taking a selected course.
Contact our office if you'd like help selecting the right course for you.
If you're taking an on-campus summer course, we invite you to visit a six-week course for a day or two in addition to the course(s) in which you are enrolled for credit.
