I don’t know where you getting your information but really…it’s not true. Sample of one…my kid declared engineering as a major the second term of her sophomore year in college…imagine that? Oh…and she never took calculus in high school either.
No one…repeat…NO ONE needs to declare a college major in high school. That is just plain poppycock.
Many…many many college students start off in one major and switch multiple times before they land where they get their degrees.
My kids both went to colleges where there were very strong core course requirements. This required that students take courses across a variety of disciplines…and yes, that included nursing, engineering, communications and business majors. And yes, some of them actually switched OUT of those majors too.
Your daughter just finished (almost) her freshman year of college. She will have a Major by the time she graduates. I think you need to recognize that this is OK. You are putting a lot of pressure on a young person to make what you think should be a career and major decision very early.
This isn’t what happens for most students. They explore, take their time…and land someplace for a major by the start of their junior year.
