So, lets say I have a decent competitive application. If I plan to major in Engineering and I state that I wanna major in a major that isn’t much popular at Stanford which might increase my chances and if I get accepted, am I entitled to major in that subject or can I change majors?
At Stanford, you don’t apply to a major department.
Although you indicate an interest in a major, they know perfectly well that most students will switch majors. Yes, getting in as an expert in Native American history probably isn’t as difficult as getting in leaning towards CS, but they don’t figure out what type of person you are right now by your indicated major. If you’ve done all of the science/math teams at your school and no humanities, and then indicate that you wanna study African American studies or something, they’ll see right through it and probably won’t like it.
They figure that out based on your ECs and classes, not your indicated major.
