I'm going for social sciences and I just picked my courses. I have all courses from social sciences except English 1C3S and Geography 1HA3. I was wondering if it is mandatory for students to have to take course from specific facalties. For example, you must take at least 1 science course

Noooooooope.

Most honours social science programs require six units of humanities or religious studies courses as elective, but they don't need to be completed in first year.
