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.
At least when I went through the rate was flat and if you wanted to overload and get permission, you were free to knock yourself out. The majority of my semesters were 20+ credits, and I saved myself a year of tuition that way. Most courses didn’t have course fees.
Oddly enough, between scholarship and everything else, attending Cornell ended up being cheaper than attending the University of Oregon or SOSC (I grew up in Oregon so I applied to both—my Dad is a SOSC alumnus and Mom attended there but ended opting for the Mrs.—while there however she did very well in some of the last courses, if not the last course, offered by Angus Bowmer). However the cost of state schools in Oregon went up a fair bit between when you went through and when I was applying.
