Question about my class schedule for senior year?

I'm going to be a senior next year at a public school in california. I was just wondering if it would look really bad not to take a science next year. I took regular bio freshman year, regular chem sophomore year, and ap bio junior year, and i dont plan on taking a science next year. I am going to take 4 AP classes next year and Calc C/D, but im not taking any science. if i do take a science, it would probably be physics. but does it look really bad if i dont take one at all? i want to go to berkeley, ucla, or possibly an ivy league school like columbia or dartmouth.
