This is probably just coincidence so don't take me too seriously but here's what I've noticed:
The professors of my biology/chem courses: "Hey buddy, don't be afraid to ask questions we've made sure to try and make things easy to understand. Here are some extra resourses for you if you're having trouble. We've structured the marking so that you have lots of opportunities to catch up if you have a bad week etc. Good luck! So proud of you all! 🥰"
The professors of anything to do with math or tech:
"LISTEN HERE YOU LAZY PEICES OF SHIT. IF YOU DON'T ALREADY KNOW EVERYTHING I'M SUPPOSED TO BE TEACHING IN CLASS THEN FUCK YOU. WE HAVE ONE TEST AND IF YOU FAIL THAT THEN YOU'RE FUCKED AND IT'S YOUR FAULT FOR NOT READING THE EXTRA RESOURSES I HID WITHOUT TELLING ANYONE THEY WERE THERE. WHAT? YOU HAVE A QUESTION? THAT'S A YOU PROBLEM, IDIOT! 
"
Some of my CS professors provided us with an intense amount of notes that they made. I love how I rarely had to get a textbook or something
One networking professor in particular didn't give a single fuck about teaching, but most of the main professors were pretty good.
I thought I failed a class in my final quarter and I emailed the professor about it. He basically said " It took me 7 years to graduate and I ended up fine, git gud kid". But I still passed it somehow?!? So I guess he was messing with me? Or I just didn't understand how the grading worked
