Hello,
Does it help your admission chances if you are applying to study in a major that represents only a small percentage of students? So if you chose computer science at a liberal arts school that has less than 3% of students in that major, is it slightly easier or more difficult to get in?
Only if your college admits by major.
And if it does admit by major, it is likely because some majors are “full”, so that enrolling and then changing into one of the “full” majors later can be difficult.
This is one of the most asked questions on this site. Colleges are fully aware that applicants might “game” the process by saying they’re a prospective Classics major or something. If you happen to have some significant experiences in an unusual concentration and indeed, wish to study it at the college level – go ahead.
But you’re not the first to wonder about this nor ask. Most collegians switch majors anyway so colleges don’t place much weight to this other than those that accept directly into the major/school (eg. nursing, music, engineering, etc).
At an admitted students’ reception, I met an young lady who had studied African artwork – while traveling extensively with her parents (diplomatic corps?). Her work in the field, even before college, was rather extensive. HER statement of intended area of study came with clear evidence.
