Should I do bafe?

I'm a grade 12 student needing to apply to uni soon. I wanna do bafe and will most likely get in, but I heard investment banking and other main jobs that the course is made for require you to work 60 plus hours, which I would absolutely dread doing. Are there other future prospects that have a decent pay (that make bafe worth studying rather than another degree) and normal hours? Also, what is the drop-out rate from this course as I heard that some cohorts that were initially 100 students only had 30 by the 3rd year (wanted to know if this was really the case). Was thinking of doing the course cz I'm interested in maths and am probably getting a high enough atar, but also find work life balance and money important.
