I got admitted to IIT and NIU although I am still waiting on FSU, UTD, UK and UIC. Any of the last four I mentioned I think are better than IIT and NIU considering that I am looking for a decent program in condensed matter (mainly nano, low temp & matter phases, superconductivity). However let's assume I don't get into any other school: what should I choose? NIU or IIT? Other thing is, I have to make a decision soon for IIT (April 1) but the other schools I'm waiting on will notify me early April. I don't want to accept on IIT and then back out if I get something better, that's not kosher, I think. I don't want to push too much in the other schools for an answer because maybe they'll just reject me right away. What should I do? Please, any recommendations will be greatly appreciated. Thanks.
