Note that most architecture courses don’t transfer easily to other majors so you need to be pretty sure about it if you choose that as a major. Also acquaint yourself with the differences between 4-year preprofessional BA/BS degrees majoring in architecture vs 5-year professional BArch degrees. Some colleges require a portfolio for admission while others don’t.
In general, all the above majors tend to be somewhat more competitive than overall admit rates for colleges, so bear that in mind too.
