Wharton - Actuarial Sciences

I’m really interested in applying to Wharton ED this year for actuarial science but I don’t really know a lot about how the major itself is at Wharton. Could anyone give me some more info on what it’s like to study that at Penn? Also, would it be bad if my common app doesn’t really mention anything about me wanting to study actuarial science? On my common app, I focused more on my character through talking about a sport that I play so I was thinking of just focusing more on what I want to study in supplemental essays. But also, how would one show genuine interest in this subject? This is something that I want to study because it seems really interesting and because I have a family history in this area but that would most likely be lacking for the Why Penn essay, right?
