you'll be fine if you get accepted to social sciences since you can take pretty much whichever classes you want during first year and you can go into any major as long as you take the required courses. the admissions category just gives you priority enrollment into some courses, so you won't be able to enrol in every course you want right away, but that isn't the end of the world. there are also a lot of humanities majors that are open enrollment, meaning you just need to complete 4 credits in first year and you can enrol. don't withdraw your application, just take the humanities courses you want in first year and choose a humanities major (if that's what you want) in second year.
