Only when studying on a Colby program (i.e. Colby in Salamanca, Dijon, St Petersburg, Bigelow Laboratory, and exchange programs), you will be billed in the same way as a semester or year on-campus. If you are studying on a non-Colby program ( majority of students) fees will be billed by the host institution, and paid by you (your family), not Colby. The specific program fees vary..
