I think that’s a good choice. And certainly do keep focused on your projects as EC’s – colleges definitely want students who are engaged and have a passion for something.
Don’t worry about negativity from other posters. My daughter got into Barnard with no high school math beyond advanced algebra, and only 2 lab sciences-- admissions is holistic, they are looking at the whole picture. They look at the high school curriculum in the context of the student. In my DD’s case, her semester abroad mean that she simply couldn’t fit some courses into her schedule. I wouldn’t recommend that path for other students - but the point is that the schools look at your high school curriculum in the context of you interests and talents. My d. attended an arts high school that didn’t even offer AP Calc. So there isn’t anything missing from your record, assuming you take some AP’s and have a well balanced course load going into senior year.
And you are definitely in the running for Barnard. No guarantees, of course – but overall you are the type of student they like to see.
