U British Columbia for Bachelor of International Economics or McGill for BA in Political Science??

The end goal for me is law school and I’m debating between these two schools and programs because I don’t know the best path for me. The International Econ program is appealing because it’s a small program of only about 80-100 students and there are a lot of opportunities integrated into the program, like internships, co-ops, and exchange programs. Although, the program is more difficult, compared to a regular BA which I would do at McGill. McGill is appealing because of its reputation and because I am an IB student, I can declare my major right away, and because it is a BA, it would arguably be easier to get a higher GPA and to get into a law school of my choice. idk if the opportunities at UBC, outweigh the difficulty of its program?

Neither program will necessarily be easier or more difficult to get a higher GPA. Your GPA will depend on you and how hard you work which will depend on how much you enjoy what you are doing.
