See that, I can believe. I don't remember room and board costs, but I DO remember my tuition bills, since I paid them:
1981: $5800
1982: $6700
1983: $7200
1984: $8100
That's in line with what you're saying, just moving out a few years.
I also remember the regular loan was $2500/year, then a secondary loan was $1500/year. Private loans were also available at that time--I remember getting mailings. The names have changed through the years.
Of course, if this woman also took out graduate school loans, she could have borrowed much, much more. Also, some types of loans begin accruing interest from the loan origination date, rather than deferring until graduation. So, that's potentially 4 more years of interest.
