Not sure if you have gone through the few Actuarial Science threads in this forum. If you haven't, do it. They are very comprehensive although I am not sure if UWaterloo has been covered much.

UWaterloo is the university in Canada that provides comprehensive co-op programme. Co-op, unique to Canada education, allows you to alternates between studies and internships. For courses like Actuarial Science where experience is important, co-op helps a lot. That being said, the conventional way, study study study graduate and work, is still a good way as you get to graduate faster.

Somehow, I feel that you are just being blinded by the fact that you are able to get into course Z offered by uni Y for which uni Y is famous of course Z. But it doesn't make sense if you do not like course Z to begin with. For instance, studying Performing Music in Julliard - will you take it if you were given the chance.

Don't be blinded by that. Sit back and take a look, what do you really like? Is it Computer Science? (BTW, UWaterloo is quite famous for CS as well, so does their engineering. LOL)

TS,

The biggest issue of becoming an actuary does not lie in your Bachelor degree. That is just like the foundation. What decides if you are successful lies on your life after graduation, where you are required to work while study to sit for the few professional papers.
If you cannot see this, or think about this, you could drop out even after your graduation.
