Required Science Courses for CS Majors

Hello! I am a prospective freshman who will be majoring in Computer Science. I am trying to figure out the best course of action when it comes to the Science requirement for CS majors. Part of it requires you take either Phys 1 and Phys 2, Chem 1 and Chem 2, or Bio 1 and Bio 2, and you also need a lab requirement to satisfy general education requirements. AP Biology takes care of both of these requirements, given you pass the test.

​

I've got two questions on this. First, is it worth it to cram in self-studying for AP Bio (since I'm not in the class) to try to knock out these requirements, or should I just take the classes at UMBC? Second, if I did forego the AP test, which series of those three options is most entertaining/easiest/most fun?

Thanks in advance for any responses.
