Cal State Credit Requirements?

So I'm a junior and am going to be a senior this up coming year and I already know that I want to major in film and attend school at San Francisco State or any other Cal State. We are picking our classes for senior year right now and I don't want to take another science class. I've already done Physical Science Honors, AP Biology, and AP Chemistry, but PSH doesn't count towards the a-g requirement. Do I have to take another science class, because I really don't want to do AP environmental or Physics. Can I still be accepted to a four year university with only two years of a science class?
