For UCLA extensions, you would need to complete Life Science 1, 2, 3, and 4, Physics 6A, 6B, 6C, Chemistry 14A, 14B, 14BL, 14C, 14CL, and 14D. That's 11 classes, plus the two labs. UCLA extension courses vary in price. Check out
www.unex.ucla.edu. Also, for the physics sequence, you need 2 semesters or 3 quarters of calculus. I believe the physics and chemistry sequences "begin" with the first course in the Fall, and so on. I'm a UCLA undergrad now, and I wouldn't recommend taking science classes there. They are very, very competitive, and somewhat impersonal. Many of those extension classes are an all-day Saturday thing, so I don't know how many you can take each quarter.
I'd opt for a Cal State if I were you. I'm leaning towards going to SFSU beginning in the summer of 2004. I've heard many good things about SFSU. You should go there too, and we can become study buddies
