<p>Definitely go on a visit and get the overall feel of the university. You have one of the best public universities right in your state and discarding it without even visiting just because of the size cannot be considered anything other than foolish. </p>
<p>UIUC has excellent World Class physics, chemistry, math, engineering and computer science programs. People are paying 40k a year but you get it for only 24k a year. I really hope you have take its advantage and get the most out of your tax dollars.</p>
