I just got accepted into the CS major, stats major, and comprehensive CS specialist POSts among others. I'm trying to decide between doing a CS and stats double major or doing the CS specialist.
I enjoy programming and CS but I don't want a job that is 100% programming, I'm also interested in stocks and quant-related fields.
If I choose one of these POSTs and then decide the other is a better fit, which one would be harder to get into later if I end up changing my mind. In other words, what option would it be better to choose now so that it would be easier to potentially switch to the other option later?
