Have no idea why I didn't look for books by Margulis instead of contenting myself with ones that occasionally mentioned her, but that error has now been rectified. How can I know if I have what it takes to get the biology degree, and what kind of job would I get with it even if I did? Could try taking the Anatomy and Physiology class. A&P is known to be a real ball breaker at NIC....a weed out class. Nevertheless, I've always wanted to take it. They have real human cadavers being dissected in there! Probably the class is filled already with prospective nursing students.
