1) Behavioral science just need to be complete before matriculation (I did my last one at a local community college over the summer)
2) It's nearly impossible to get IL tuition - you need a IL driver's license dated at least a year before you APPLY, tax returns, car insurance/registration, voting registration, and to have declared it on your AMCAS.
For poster above - if your parents move, you're still a dependent, and your current state school disowns you, you'll have a better shot at getting IS.
3) UIC accepts a slightly wider range of GPA's/MCATs (mostly because they have a huge class, and it's all about averages). It's usually from students with special circumstances - non-traditional, advanced degree, etc. E.g. a student who had a mediocre undergrad GPA 10 years ago, a pretty good MCAT score, and a successful business career in the middle might have a better chance than at some other schools. They tend to count your most recent work heavily. Ultimately, they need people who are going to succeed in medical school and on the licensing exams, so they can't be too flexible. Also it's not enough to say "I had a terrible semester in undergrad due to X disaster", you have to say what you learned from it.
