I applied in 1985 (starting in 1986). Applied EA to Yale, deferred, admitted regular (seemed a lot of my friends at Yale were the same). Wound up applying to 8 schools RD – other Ivies were Dartmouth and Princeton. In the end, I was admitted everywhere I applied – 710V/700M SATs; I have no idea how that compared with other applicants, I don’t remember any of that being published. I did interview with alumni at several places – I remember distinctly different vibes from the Yale, Dartmouth, and Duke interviews!
I went to a private school in the south that was pretty college-focused (fully a third of our small graduating class were National Merit Scholars or close to that, and one student had a perfect 1600 on his SATs). But even so, we didn’t start thinking about college applications until late spring junior year, when we did a bus trip up the east coast over spring break with another private school in our city. I don’t remember doing any prep for the SAT – I don’t even remember taking it; I def only did it once. I remember I had two basic essays that I could use for all the applications. No one was asking “why Yale?” or "how will you add to our community and how will our community be meaningful to you – academically and socially – in 300 words… Which was good since everything had to be typed. I remember finding somewhere that Yale’s admission rate was between 18 and 19% the year I got in. There were still surprises with the admissions process; it wasn’t all numbers, but it seemed more predictable.
I don’t remember admission days, but they did have something orientation-like over the summer, I can’t remember the details – I did an outdoor orientation trip, a week of camping, a program that was only a couple of years old at the time. Even then, it was a mix of old money, multigeneration Yale people and first-gen students from all over the country. The overall vibe was prep school+NYC cosmopolitan, but in truth that wasn’t a majority of the school; they just had a presence (an they often came in knowing each other!).
