I did a biochem undergrad and was surrounded by premed students. Every single one of them was a North Face-wearing, click-y, "there to get the grade" student. They didn't display the same kind of awe for the amazing biological processes we were learning about, and they certainly didn't put in any legwork into undergrad research projects. They weren't nerds. They wanted a job with prestige and money. Several of them were bullies that talked bad about us and were not fun to be around.
I spent my time thinking about human regenerative cloning, transfecting biochemical synthesis pathways into things, the metabolome, connectome, etc. They used flash cards and socialized and would quickly change the subject when talking about biology topics. The material didn't matter one bit to them.
Complex things were gamed even more. They spent their time memorizing o-chem reactions rather than following the electrons.
My experience led me to believe that there are doctors that are only after the title and wage. They're not domain material geeks like us. I just question how many are actually like that, because my school was loaded to the brim with these people.
