Mount Allison offers special topic courses to explore subjects or interdisciplinary areas not covered by regular departmental offerings.
Many individual departments and programs (such as Biology, Drama, and others) also offer specialized or rotating topic courses — often designated with a 1991, 2991, 3991, or 4991 code (e.g., BIOL 1991, BIOL 4991, DRAM X991) — to cover current research advances, guest faculty specialties, or experimental pilot classes.
