I originally went into premed in college and struggled a lot, I had other family members who were premed & or doctors and didn't understand how I could be getting C's in biochem or physiology.

I finally gave up realizing there was no chance i was getting into medical school with bad GPA and switched to EE where I admittedly had to study a lot less and got much better grades. People underestimate just how difficult bio is and i think the high volume of information and importance of memorization is just training you for medical school where the volume of material you need to study is magnitudes more.

I don't envy anyone who went through it. When it came to physics, math, circuits, etc. you could really get away with just doing a couple practice problems and understanding the core concepts. The experience of going through two very different fields and being an utter failure in one made me believe that people's brains can just be wired differently.
