If you don’t want to spend $1900 sign up for bowling, or weight lifting, or whatever and do rock climbing on your own.
You wouldn’t save that much; the excerpt said that the standard cost of a one-credit course was $1,575, and the other $315 was a course fee. No telling what the course fee for other activities might be.
I wonder if tuition is $1575 for every credit hour. That would put a fairly easy load of 16 hours at $25,200. I was paying not much more than 1% of that while attending a state university in Oregon in the mid-70s.
