I go to Florida Atlantic University. In the spring semester I took my Calculus class at Palm Beach Community College - it was approximately $250 for the three credit class. This summer I have two classes at FAU - total was approximately $870 for both, so one class is $435. It's almost half the price to take a class at the Community College level around here.
ETA:
I just jumped onto UCF's website. Their pricing is: $150.85 per credit hour for a resident and $666.83 per credit hour for out-of-state. That's cheaper than my school which is FAU - $139.55 for a resident; $584.14 for out-of-state. This is for the current year, so up 15% it shall go in the fall.
Valencia Community College, which is probably the closest to Orlando is $87.36 per credit hour for Residents and for Out-of-State it is $330.88 per credit hour.
It takes a year to establish residency here, which is why so many do the Community College thing and then transfer once they have established residency.
