All are great options for your intended major. I would say in terms of social scene, they are all pretty different. McGill’s social scene would be more off-campus events in the city. If you’re worried about Barnard’s reputation, I can assure you that it is pretty similar to Columbia’s- they have a great alumni network with many connections, and your diploma will even say Columbia University on it. If you want a more traditional college experience with a campus, social life, etc. I would say one of the schools in the US. Although McGill is great, you wouldn’t be as involved in a community like you would at the others. Hope this helps. Good luck!
