G. Mark’s Answer
Realize that biomedical engineering covers an enormous range of knowledge areas. A degree in biomedical engineering will require biology, math, multiple sciences and knowledge of mechanics as well. You won't have to limit yourself to being only a biomedical engineer, but can probably do just about any engineering job. My original degree was in computer science, after which I went into electrical engineering. But I eventually found work in medical devices, and just about every aspect of my education came in handy at one point or another. Staying flexible and willing to solve any problem will create a lot of opportunities for you. My advice is to stay curious.
