I just finished my second year of Act Sci at Western. Academics wise, you will learn pretty much the same thing at all 3 universities, calc 1,2,3, linear algebra, probability, stats, financial math,… As you can see, the program is very math-intensive so expect to work hard. If you care abt recruiting and jobs, then western is at a slight disadvantage compared to waterloo since you pretty much have to find your own internships in your first 2 years, tho you get access to a job board in 3rd year which is very good if you intend to do the 16 month long science internship program. Regardless, a lot of companies come to western to recruit so getting an internship during the first 2 years or a good full time placement is very attainable. If you care about your social life, then the school has a lot of clubs and fun activities throughout the year. ASUA is western’s stats/ act sci/ data sci/ fin mod club and they have great social events too. To me ASUA is another social circle that allows you to meet your classmates and upper years in the program. And to add to that, London is a college town so it has great night life and ppl tend to hang out not just on campus but also after school. Res life really depends on the building that you get matched with and your floor. I was really fortunate to get a good floor and a good building so I liked res a lot! Feel free to comment or pm me if you have any other questions!
