Interestingly (or not) the same thing happened my freshman year in 1973. I was tripled up for a couple of days until they figured out who didn’t show up at all (summer melt). I was then in Monroe in a normal situation. Didn’t affect class selections for me that I was aware of, but of course class selection was stone age then. Students would think it was a Saturday Night Live skit or something if they saw the ballrooms or gyms full of tables where people would go and get punch cards or entry forms for each class.
Tulane was at about 100 over target, so I am sure there will be adjustments. Also might be another reason ED was introduced this year. Tulane is hot, which is great, but not so much when you are in that situation right away freshman year. I guess it all worked out though?
