First off, you do have elective requirements you have to meet, for example you need 12 arts credits and 3 credits from each “category” of science minus one (https://science.ubc.ca/students/requirements/faculty, see academic calendar for more details). Speaking from a GPA perspective, I find that if you’re actually interested in a subject you can probably do better in those courses than so-called gpa boosters (I heard ATSC 113 is no longer a GPA booster anymore, as well). Another thing to note: I haven’t checked, but I would not recommend taking WRDS 150 with a bad professor because of how much the syllabus differs and the class sizes are small. Much better to take an ENGL course IMO.
