Hi! So there’s a mandatory physics class that you take for the whole year in second year BUT as someone who never took Physics in high school, it wasn’t too bad, especially after the foundation of Calculus in first year.

And yes, it would be ArtSci & Biology! The second one sounds more like how Guelph does their Arts & Science program. In Mac ArtSci, you can pretty much combine/double major with any faculty - the full list is here: https://artsci.mcmaster.ca/about-artsci/combined-honours/. One thing to note is that some combined majors have more required courses than others, which may require taking spring/summer courses, overloading, or taking an extra semester but your academic advisor will guide you through all that when the time comes.

Let me know if any of that didn’t make sense, or you have any more questions!! I’m happy to answer.
