When did you graduate? Between 2009 and 2013 my college cost was roughly $40k per year. This was about the average for similar schools (RIT). My wife went to a small liberal arts school during the same time and spent roughly $50k per year.
$20k seems like an incredible bargain, but my view is probably warped.
2009-2013 as well, (accredited) state school (of which I am a resident), cost me a little less than $10,000 per year for a Computer Engineering degree. However, my junior year, engineering classes level 300 and above increased by 25%, continually increasing per year until they were 100% more expensive. I narrowly dodged that bullet.
Perhaps the west coast is cheaper? $50,000 per year seems like lunacy to me.
