L&S includes lots of science majors plus math, so there are STEM majors there (where the criteria to declare is typically completion of prerequisites with C grades and/or 2.0 GPA). However, CS, DS, and statistics are in CCDSS, so you would have to go through comprehensive review to major in those (though probably statistics is less difficult to get into, or take upper level courses as a non-major, than CS or DS).
What majors are you (as opposed to your parents) interested in?
