Associates Degree Question

[ss20ts]

Example. The CC near me:
$90/cr
allows 45 cr from test outs
accepts ap, clep and dsst with spelled out equivalencies on website
CLEP and DSST test center on site
free tuition for those over 65, free tuition for adults over 25 who meet certain criteria, huge scholarships for young students, pell grant more than covers tuition cost if full time
I got an associate degree there. Only 17 credits in residence at the CC. My cost: I got paid $300.

$90 per credit? Holy cow that is cheap! Here's it about $200 per credit for just the tuition. Then there's the fees which are often as much as or more than tuition. It's ridiculous. I can actually attend an out of state public school for less. That's just crazy! 

Here tuition isn't free for senior citizens. They can audit one class per semester if the class isn't full. They don't get grades or credit. They can't participate either. 

Free tuition for adults over 25? What state is this?
