Alternatively, if the college train just feels like it’s bearing down on you too fast, make your best call and commit to a school, and then defer for a year and spend the year working to save up some spending money, and getting coached both for the vocal auditions that you’ll have when you get to college, and in coding-type stuff so that you’re more caught up with your CS peers when you start your freshman year. It doesn’t seem as if a year to regroup and prepare would do you any harm at all right now! In fact, at CMU, it’s entirely possible that you could defer your CS admission and still go through the CFA admissions process that you didn’t do this first time, so that you could go in as a full double-major. Just a thought that perhaps doesn’t appeal, but just know that you can take a breather if you want or need it!
