@bayarealover I have found that to be true for some of them, but not all. I had a wonderful chem professor who knew my name out of 700 students. If you go to the prof’s personal office hours you can definitely get to know them well and get help, but sometimes, I’ve found the most effective way for me to learn has been studying with other students or talking to helpful TA’s (you have a discussion of only 20 people with a TA so it feels like a small class). Depending on the class, it can be hard or not so hard, but a lot of college is teaching yourself. I honestly like it way more than I thought because it gives you the ability to study in the way that is most effective from you rather than what the professor thinks works for you. You can totally get other kids together or get a tutor or go to a million TA and prof office hours - there are a ton of resources! Some clubs even offer free tutoring!
