The MBTA Semester Pass Program provides bus, link, and commuter rail passes for the fall and spring terms, October through January and February through May. GSAS students can purchase semester MBTA bus and link passes at a 50 percent discount by completing the MBTA Semester Pass form and returning it with payment (check or money order, no cash) to the Office of Student Affairs on the 3rd floor of the Richard A. and Susan F. Smith Campus Center by the deadline noted on the form. Once available, student purchasers will receive an e-mail to pick up their passes in Cambridge or in the Longwood Medical Area.
