Try to ask more/better questions specifically about IU and you will get better responses. Most of us know nothing about any of the school except IU. We are not here to do your research for you. I’ll try to answer some stuff from your original post:
You can party pretty much any time you want at IU, but nobody is going to force you to party. What do you mean by “convenient and accessible”? There are buses that easily take you to Bloomington from the Indianapolis airport, but there isn’t much outside of Bloomington. Kelley is a top 10 business school and I have been satisfied with the course quality so far. Also just so you know, you are not locked into a specific major at Kelley right now and you don’t have to decide a major until junior year.
This thread might be helpful as it answers some other questions about Kelley.
