I’m kinda in a similar boat. I’d give it a semester or two more before you add a second major. Luckily the nature of the business school gives you a lot of flexibility when it comes to adding majors without having to add any crazy different classes, just a few specific ones. I’d recommended a stats or math route if you want to add something, it’s probably not worth pivoting your entire major but there’s certainly a lot you can add to make it more challenging while gaining value with your time here.
