Harvard and Wharton teaching styles

[guest23]

I'm trying to narrow down my list of "far-reach" schools to apply to and would appreciate any insight about the curriculum and teaching styles at these two schools. Specifically:

1) HBS - Do 100% of classes really use the case method? (even statistics?!) If so, are students given supplemental material/problems to go through outside of class to pick up the more quantitative aspects, learn basics like DCF etc ?
2) Wharton - I keep hearing Wharton is extremely "quant-focused". What about the curriculum is more quantitative than other top schools? Is there more theory derivation, more number crunching...?

Thank you!

I'm considering applying to Wharton, and recently I found out that they put special emphasize on community involvement and volunteering. Luckily, that's one of my strong points since I've been volunteering for different community projects for a while.
Now I'm trying to understand if it's true and how much weight should I put on this in my application. I heard it from 2-3 students and alumni I spoke to, and also read it here:
http://aringo.com/Wharton_MBA.htm

"Key points in an application: Your professional development; your personal development; your way of using the blend of the former two in order to give back to the community. "
There is also a list of traits and their importance to the Wharton MBA program, where "community/society" is ranked 3 out of 4.

What do you guys think? Does Wharton really prefer applicants who are giving back to the community? Anyone heard anything about it?
Thanks!
