I would choose the IS school... save a ton of $, work my ass off on the boards and end up in the same place I would have if I had attended Case or Jeff (which are both awesome schools).
I'm looking to attend any of my instate options over Case or Jeff at this point but it kinda sucks that im a Cali resident for financial reasons in the end the some odd 40k I would save in loans will probably be closer to 100k saved after interest paid. That being said I absolutely think Case is awesome and was so impressed after interviewing there.. but it is mucho $$
