HATED gen chem lol!! I like nutrition a lot, but really didn't care for genetics. I do a lot of stuff with genetics now in my research lab, and learn way more they way then I did in the class. My teacher was god awful, but apparently all the genetics professors at my school are horrid. I like my classes for the most part (zoology major), and the prereqs weren't too bad at all I feel! Not a huge fan of physics but it was doable (made B's in both). I really enjoyed technical writing. I'm taking cell bio next semester for my major and for auburn's cell bio requirement.. And it's supposed to be the hardest undergrad bio class at my school so I'm terrified 🙁
One thing I really hate about many prereqs is that it's mainly the luck of the draw. If I would have taken physics one semester earlier, I would have made an easy A (literally 90% of the class made an A), whereas only 5 people out of 80 made an A in my class. And my biochem class was a similar situation. There are easy teachers or hard teachers at my school, and unfortunately the easy ones don't always work with my schedule. It doesn't go for all classes, but I feel like a lot are this way, especially for classes that lots of people need to take (chem, physics, stats, etc). I think you learn more in harder classes because you MUST spend more time studying, but unfortunately admissions doesn't see how much you learn, they only see the letter grade on your transcript 🙁
