The academic advisor will answer these questions for her and let her know how essential it is to follow the course roadmap and how feasible it is to double major. I don’t think any college hangs entering freshman out to dry in terms of first semester class selection!
My D is in a biological sciences major that lists 5 lab sciences on the roadmap for the first two semesters. She mentioned that her advisor strongly advised against following that roadmap exactly from their very first meeting - it seems that very few students actually attempt to take three lab sciences at once. (At least at her school in her particular major - these aren’t kids who are planning on PhDs or MDs or working in labs etc. - the 10 credits of physics is probably overkill!).
