The first advice I will give to Bio Medical Engineering students is to never be discouraged. This may or may not end up being a problem for you, but if you end up doing poorly at any point, don’t get too discouraged. For every student you see who’s running around with a 4.0, you’ve got people who are failing classes. You’ll just be one of the ones who didn’t quit, and that’ll mean a lot to you when you finally get it.

My second advice to them is to always have a back up plan.
They have to think broadly and be proactive about their future right from the unset you have to think about what you want to end up doing with your degree specifically. Did you want to work with bio-transport of pharmaceuticals? Bioinformatics? See how many elective hours you have and what you want to do with them. See if there are any minors that would mesh well with that.
You should always attend career fairs, if nothing else, you’ll be used to it, and you might see some opportunities that you like for later. Who knows, they might even recognize your name later on.
