2 years ago I called Nova to see if they would accept a substitute for the biochemistry requirement because none of the universities near me offered it and they recommended taking it online at the University of New England. I used the class as my prerequisite and was admitted to both campuses. The U. of New England also offers the 2nd semester biology course online and Nova may accept this course, too. I would call and confirm this with the admissions department.
