A cherished GSSM tradition

What better way to start the year than to focus on one thing that interests and inspires you? INTERIM classes let you ease into the new year, tapping into undiscovered talents and exploring new personal frontiers.

Several courses include travel, nationally or internationally, and field experiences. In years past, groups have visited places like Silicon Valley and the Galapagos Islands.

Course topics are diverse and include science, technology, art, music and drama. Interim courses are taught by members of the GSSM faculty, along with visiting professors from South Carolina colleges and universities.

  • Some courses might not occur if the minimum number of students is not met. If the maximum number of students is exceeded, placement will be based on requests in the order they are received.
  • If you are requesting the same class for the second year in a row, you must receive permission from Dr. Martin.
  • Courses vary in content and cost. If a student registers for a course that has a fee, the student is responsible for payment in full for the course, even if he/she later withdraws or is dismissed from GSSM prior to or during interim. If this occurs, GSSM will not reimburse payments made, and the student remains responsible for the full payment of the course fee.
