AP Bio or AP Chem?

Hi, I am planning to go into nursing and get a BSN, and I was wondering whether to take AP Bio or AP Chem for my senior year in high school. Which is better as a pre-nursing major, and do CSU’s accept AP credit? I can only take one of the two, and wanted to know which is more recommended. Let me know. Any help is appreciated. Thanks!

What science classes have you taken already?
