Well, if I choose CS, I'll really want to do the cool stuff (AI/data science). Our university offers something like AI Master's, so the required Math background will be (hopefully) provided. I skimmed the study-plan for the General CS bachelor's, and there's bunch of linear algebra, discrete mathematics and combinatorics classes.
