I have never worked as Biomedical Engineer student, but if one advice I have to give I would certainly say to make contacts. Take as many co-ops/paid or unpaid internships and build connections. I am not saying GPA is not important but it is definitely not the end of the world. Once you get your first job, no one will look at what GPA you passed out with. I was one of the student, who have to have As in all subject but I realized I have spoiled my health due to that, I would never do that again.
