Questions about Duke economics and political science majors

Hello TheNerdyOboist!

I just got into Duke’s class of 2024, and it looks as if you’re doing exactly what I want to be doing!

I was admitted into Pratt, but I’m thinking that I want to do a dual major in CS and Economics with a concentration in finance.

How should I go about accomplishing this? Should I call and switch to Trinity now, before matriculation, or do you think that I could wait until after my first semester at Duke, to make sure I want to switch?

Thanks in advance.
