This is accurate, but what I'm saying is that people define "difficulty" differently. For some, it's far easier to do something conceptually complex than it is to sit for 6 hours and memorize drug names and mechanisms. For others it's much easier to sit and write a paper for that amount of time. And some people are so used to the whole "sit in a quiet room and memorize until your eyes hurt" thing that they find it "easier" than trying to get through a math problem set. I have a family member who genuinely found physics and math to be intuitive, so she rarely had to really sit and study. She once took a bio class and very nearly failed it, because she just wasn't used to that kind of work. Of course it wasn't conceptually complicated, but it was harder for her to study and memorize than it was to get through a physics problem set. One of my closest friends from college was a comp sci engineer and I was always so envious of his workload- not that it was easier than mine, but he could just be "done"- he wrote the code, it worked, there was no debugging, it was simply done and he knew he'd get an A on it. Meanwhile, I (a natural science and liberal arts double major) could stare at my textbooks for days and not know if I was studying what I'd be tested on, and I could work on papers forever and not know if the professor would like my writing style. It's just different frustrations and different ways of interpreting "difficulty". Unfortunately, most people don't acknowledge that, and that's what I find annoying.
