Graduating BC with $35k in debt is 100% worth it if you want to do IB. Even if you don’t like IB specifically, come to terms with the fact you will NOT be working on the street from that “unknown” LAC without getting extremely lucky and working a network.
You’ll make at least double the 30k in excess earnings in your first year if you do IB vs. a job from that unknown school with no connections (assuming you have the grades, do the right things to get into IB).
