Way too many schools out there, too, to ever make a statement on this. Although I've noticed Dartmouth grads tend to be annoying. Never met one that wasn't.
Had a roommate once who went to Dartmouth who was pretty cool.
Which just goes to the major point I want to make here: there is tons of useful advice in this thread, BUT you need to filter out what applies to you. For example, you've got conflicting advice on morning classes. For the majority of students, staying up late is part of college, so morning classes are bad. But you may know yourself to be a morning person. You may love getting out for a run at 6am and getting the blood flowing. In that case, the advice on morning classes doesn't apply to you.
To which I'll add another point in the same vein: figure out what makes you happy and do that. I was an English major in school, which I (mostly) loved. Then, because I went to an Ivy, when I graduated I had this self-imposed expectation that I was supposed to either be in finance/consulting or go to law/med school (this was back before startup was big on the east coast). HUGE mistake, and it was only after 20 years trying to find "creative" business/finance roles that I started writing again. You may well be fascinated by big business, mega deals, and how the economy works, and if that's the case, great - keep going for finance. But have an honest conversation with yourself to be sure: what do you really like to do? Do that, and you'll enjoy your life a ton more - and likely will be more successful in the long run.
