<p>It’s very funny that i came upon this post because I am in the exact same situation. Well mostly. UCLA and UCSD are both my top two choices and I am a bioengineering major as well. I would say that you should visit both schools and whichever school you feel more connected to would be the school to go to. Personally I am also leaning towards UCLA. Let me know what you end up deciding. You could be my future lab partner haha.
Best wishes</p>
