Bioengineering Transfer Student -

First off, my apologies if I’m violating any posting rules. This sites layout is different so navigation is odd.
Anyways!
I’m looking to transfer to a decent school for Bioengineering. My dream schools would be Rice and Cal Berkeley. Stanford for prestige but other than that I’m not too interested in over achieving since I’m already 28 years old and I just really want to follow my dreams. Currently, I just got back into college and I’ve got one semester down with a 3.0 GPA. Definitely tough getting back into school after 10 years but I already feel warmed up and it’s getting easier and easier. I’m looking for some stats of people who were successful in transferring to these schools. If anyone has any advice for extracurricular activities that would help me get into the motions of BioEng I would greatly appreciate it. It’s great to be back and after 10 years of hitting my limits in various companies I finally realized why school was so important. I know I can get the grades but I need that extra edge.
