<p>UCSC compared to UCSD? I think it would be basically the same.
If you were going to a UC then Merced is probably the only one would be noticeably easier but then again it is still a UC.</p>
<p>The guy above who recommend psychobiology because it focuses on behavior as opposed to biology is really smart. The problem is if you go into neuroscience and especially goto a UC then you will be in curved classes and competing against people with photographic or near-photographic memory. So getting grades based on tests that mostly deal with memorization will hurt your GPA badly. If you do a major that is more focused on writing papers or explaining stuff then that memorization advantage goes out the window and your gpa will improve as a result. </p>
<p>In short if you really want to do med school then just get in the med school pre-reqs and focus on an easier major that you will improve your GPA. </p>
