*St. Thomas Aquinas College reserves the right to make changes as circumstances require.
The College offers intersession courses in Winter and Summer for Undergraduate and Graduate Education students. These special sessions are scheduled primarily for the benefit of students matriculated at St. Thomas Aquinas College but are also open to properly qualified visiting students. By completing a Winter and/or Summer session course a student may lighten his/her course load for subsequent periods of instruction, make up for deficient credits, or elect extra credits to diversify and enrich his/her academic program.
