Case vs UCSD (Biomed)

<p>I am deciding between Case and UCSD Biomed/Biological engineering.
I know that both schools have great biomedical program(UCSD ranked #5 Case ranked #8)
I am leaning towards Case due to the smaller class size and it is probably easier to get a higher gpa because of semester system at Case. Also, I like the fact that it is somewhat related to Cleveland clinic! (I want to go to med school later)
The problem is that I might have a chance to get in a research program in oncolytic immunotherapeutic area at UCSD cancer center because I am currently doing an internship at Jennerex Inc, and professor I work with has connections in UCSD med school. But I don't have any connections at Case, so It is likely that I can't further my research anymore.
Should I give up my 1st choice for my future career or Should I go to case and be happy?</p>
