You might be able to qualify for a B. Science at some universities. If you have to do Arts, use your elective space for Computing subjects, then see about a transfer.
Tbh, Arts degrees aren't that bad. I'm doing one (although I've considered B. Social Science). It depends on your major, attitude, experience, interests, etc. Sure, your job prospects may not be as big as another degree, but going after $$$ may not be the wisest course of action for everyone. Also consider: what skills do you want to develop? Arts degrees aren't for everyone, just like how Science, Law, Commerce, Medicine isn't for everyone.
Good luck.
