@evergreen5 Northeastern claims there is no admission by major, and there are no stats on anything beyond general admit rate. Of course there are likely different rates to some extent, but it’s hard to say how much effect they have.
On the flip side, changing majors/schools is so easy here (flexibility is important being a co-op school) that it would make sense to avoid the admit by major. You can change your major between getting admitted and Fall semester with no problems at all. The number of CS majors has been growing as well, not staying stagnant, signaling an increase of competitive CS applicants. My bet is that they more or less ignore admit by major, pick a class of admits + X, and if there are too many of Y major, cut a few of those and add the tail end in other areas. Also hard to say how all of that fits together with yield as Northeastern is such a common application for ivy hopefuls and the like. I’m inclined to think that major is overall a very small factor in admission based on that mostly anecdotal experience.
