Students at Marc Garneau CI have the benefit of MGCI being an AP exam testing centre available only to students studying at the school. With the exception of studio arts and some foreign languages, every AP exam is available for MGCI students to write at the school. In recent years, MGCI has hosted around 200 exams a year.
This year, due to covid-19 restrictions, exams will not be held in the MGCI building. However, exams will still be purchased through the school and provided to any students who wish to write them.
