If I'm a history major when I get into the college of arts and sciences, can I take, let's say, statistics/data science/cs (if this school's cs major belongs to the college of arts and sciences) classes as a freshman?
So I will say Im not an expert however a lot of schools allows for an exploratory program which is in essence is undecided. This lets you take classes in various areas to determine what you’d like to major in. This isn’t available at all schools however but being undecided wouldn’t affect your 8 semster in most circumstances. Not sure how it affects what college CS is in.
However another option is if you forgive the freshman requirement almost all schools have spare time typically in last 2 years where you can take CS classes and this isn’t reliant on being in the same college.
Lastly you could minor in it which adds added certification and almost all name recognizable school can easily have a pathway for a minor within 4 years.
Please note one huge caveat is some schools have extremely strict major changing requirements. Either one of the ivies or MIT has it so you have to all but retake the pre reqs so definitely look at each school individually.
To keep this community safe and supportive:
I think it depends on the school. My top choice lets all students take whatever classes they want out side of their major if they can fit it into their schedule. Another few schools on my list have competitive majors so certain classes are reserved for people required to take them for their major. Most schools however so have space for you to take one or two classes a term out side of your major.
