U of I vs. DePaul vs. Wash U

<p>I'm a junior interested in business/communications or history/political science. My GPA is 4.12 weighted; 4.0 uw. I'm ranked 2/401, with decent ECs (will have 4 yrs varsity tennis, community service, etc.) I got a 31 on my ACT, and I'm taking a pretty challenging course load for my school (which isn't very competitive). </p>

<p>I figure I'll get a lot of money off at DePaul, and I'm in state for U of I. I love Wash U but I worry about finances. </p>

<p>Which of these would suit me best, considering my credentials and areas of interest?</p>

<p>Thank you!</p>
