Internal Transfer to Stern

I am an incoming freshman at NYU in the Fall 2020. Currently I am an Economics and Mathematics combined major and I really want to internal transfer to Stern. I am well-aware that this is difficult but not impossible. I just got my schedule for the fall and I want to see if the classes I am taking this semester are ideal for an internal transfer. This semester I am taking:

Intro to Microeconomics
Calculus II
Spanish-UA-2
First year seminar

I am planning on taking Writing the Essay and maybe Statistics next semester. My only concern is because of my Spanish class. I tried to register for a Cultures and Context or a Texts and Ideas course but both were full. Should I keep Spanish or drop for an elective? Also how many electives can I take at NYU CAS? I still want to be on track for graduation and everything.

Please let me know!
