No. Entering first-year students are not granted credit for college courses taken before graduation from secondary school. However, a maximum of six credits may be awarded for college courses taken after graduation from high school and prior to matriculation at Columbia. For more specific information, please consult the bulletin of Columbia College or The Fu Foundation School of Engineering and Applied Science.
How large are Columbia's classes?
80% of undergraduate classes taught at Columbia have fewer than 20 students. Since Columbia’s Core classes are small seminar classes and since more advanced courses are meant to allow direct connection with faculty, few courses at Columbia are larger than 20 students. Those classes generally are either popular introductory lectures or upper-level classes in especially great demand.
