I’m not going to comment at all on the numbers below for the moment. I’m just going to let it sink in:
All these numbers are for flat-rate full-time. Also, starting with Spring 2005, it is in the College of Liberal Arts instead of the College of Natural Sciences. COLA is a few hundred dollars less expensive than CONS:

semester	cost without optional fees
Fall 2002:	$2,504
Spring 2003:	$2,504
Fall 2003:	$2,750
Spring 2004:	$3,030
Fall 2004:	$3,543
Spring 2005:	$3,294
Fall 2005:	$3,486
