Biology Majors at UCSD?

<p>I am currently at community college and I will be transferring to UCSD in 2015. I'm not sure what I want to do with my life, but at this point I have my mind set up on going to a DPT ( physical therapy) grad school. It's pretty competitive to get in, and most schools require a GPA over 3.3 and a GRE score over a 1000. So far my major is human biology and I want to know if this major is hard to get a good GPA in. I'm pretty good at biology but I know that classes at UCSD are very hard. Is there any biological majors at UCSD that are not so tough? I heard that biochemistry Is one of the hardest.</p>
