Business Preference major

Does that mean I can go to the actual major (accounting) later?
Do you have to be one of the best students in class in order to get into the actual business school?
I am not sure how difficult it is to “survive” in business preference major.
What happens if I get rejected from their business school after all the years? Am I screwed?
I don’t want to regret later.

It’s significantly more difficult than a general degree
