From what I collected on Darden,
Like
1. You will work extremely hard at Darden, which is a good thing.
2. Case method will enhance your skill to have an opinion and take a stand.
3. If you are decent, it is very likely that you will get scholarship.
Dislike
3. Participation is heavily graded, so everybody tries to make a point. Essentially only 20% of comments add value.
4. All courses are taught by case method. This is the single most important aspect that you need to research. You will have less time to spend on recruiting efforts. For the same result, you might end up working more at Darden than you would at other schools such as Fuqua, Ross or Yale.
5. Number of students with Virginia roots are overwhelmingly high. For those who prefer a diverse student body, this is not perfect situation.
6. Their yield seems to be miserable.
150,000 is huge investment. Pick a school where you will end up with a great job and good friends.
