<p>pick one, take some classes in the other if you’re interested. biomedical should involved some mechanical if you’re going the devices route. less so if you focus in biomolecular. mechanical will give you a broader background, but both will give you the engineering degree and skillset. take advantage of projects, research, and internships to help you decide. i’ve also found that many people take a class in a field they’re interested in but end up hating the material or the related work.</p>
