Microbial Biology vs Integrative Biology

<p>Hey, I heard that the average GPA for College of Natural Resources for the Biological Sciences are around 3.28, and the average GPA for Integrative biology is around 3.33. I was wondering why this is the case, because I've heard that the PMB classes are easier than IB classes? I'm premed, but I'm interested in both IB and MB, so any suggestions would be appreciated. Which is actually easier (higher GPA)?</p>
