This is an FYI for those still seeking places to apply.
Bad sign for the school
Last year the number of applicants to Oberlin dipped, so my guess is they are trying to course correct that number. Their new CDS is out. They had a 91% freshman retention rate. Pretty good, but probably 3-5 points below some of their peer schools. And they took 125 kids from the WL, which seems on the high side for a school that size.
Amazing how the fortunes of a school can change so quickly.
They could also be trying to not pay tax on the endowment by having more students.
How did you find this new date? I checked the website and I only found Jan 15 as the deadline for RD.
By email from Oberlin. Maybe contact the admissions department.
I also got an email from Beloit. Will post that on that thread.
