<p>Is it possible to become an RN AFTER you have completed a BS degree in Biology? How does that work?</p>
<p>Apply to an RN program. </p>
<p>Generally you will have many of the prereq., but the program will still take you at least two years. </p>
<p>Programs differ, but they may require anatomy and physiology, microbiology, chemistry, basic math, the usual English, etc… Other that that, most of your classes would be nursing courses and clinical time.</p>
