Cosmos 2016 discussion/chance me?

Hi all, I’m applying to tissue engineering and regenerative medicine and biodiesel from renewable sources at ucsd. How popular are these clusters? I have no idea how much of a chance I stand. I’m a junior with a 3.85 UW and a 4.23 W, but I have no STEM related EC’s except for coaching sci oly for middle schoolers and being a math peer tutor (I’ve only done two 30 minute sessions lol)
