So far, here is what happened for me...
When I was born, my parent's put money aside from me for college. Obviously, now that I'm going into college, I am able to go into that money so I can pay for my tuition.
At the moment, my plans are Harper for 3 years due to the transfer requirements. 30 minutes from my house to Harper isn't so bad. After all, I get to pass by Rolling Meadows =D
If you do plan on going to a community college for a year, expect something around $1500, INCLUDING BOOKS, for a semester.
Tuition for Universities will vary...A LOT. I have looked into NIU, and I already see around $16,000 right there.
Scholarships are the way to go. Sign up for as many as possible (maybe even one of those that FIRST gives

)
