Students heading to Illinois State University this fall could be paying more than current students.  The university's Board of Trustees wants to up tuition by four-point-four percent.  In-state students would pay 335 dollars per credit hour, while out-of-state students would pay five hundred-78.  They're also looking at boosting residence hall rates by three percent.  University officials say the increase is needed to keep up with the economy.  They'll talk about the proposals in a meeting this Friday.
