You had to have listed the Dyson School on your common application:
“On either application, Dyson applicants should select “Cornell SC Johnson College of Business–Dyson School” as their program of interest.”
It’s hard to get into the school. Like the above poster said, you should seek academic advising. Maybe the rule has changed, but when my son applied to CALS you had to declare a major on your application and that was in 2015.
