<p>It’s not a big deal, don’t worry about it. I’m doing a dual, two co-ops and graduating in 4 years. Just make sure you actually want to do environmental geology. The biology major will take care of pre-med requirements (unless it doesn’t have physics, in which case you’ll need to take that). Here is the catalog for bio <a href=“http://www.northeastern.edu/registrar/courses/cat1011-acad-sc-biol.pdf[/url]”>http://www.northeastern.edu/registrar/courses/cat1011-acad-sc-biol.pdf</a>).</p>
