I've been watching crash course for a few years now but I can't believe it's now actually helping me more with my psychology degree than the textbooks my teachers assign. Thank you Hank, hope you know these videos, even years later, are getting some of us through entire college courses

These crash courses are a godsend for those with ADHD. The visuals really enforce the absorption of the information by keeping my brain stimulated and engaged. The screaming helped too lol. Thank you for the lesson!

I was recapping this for an exam and I am too tired for the scream to scare me. I’m even wearing headphones. My body just did not care
