Nus bba or DSA?

I’m considering between NUS business administration and NUS Data science and analytics as my choices but I don’t know which to put first…(my score was 83.75) I wld prefer to study DSA but the cut off was 85 so if I put that as my first choice then I could be able to make it, I’m only worried that there’s going to be a lot of competition from the higher scores+ I’m also scared that if I put bba (cutoff 82.5) as 2nd choice I might not even get in any since i heard that nus rlly prioritises 1st choices😅could anyone please give some advice? Thank you!
