It’s 7am, my test is at 10am

I am literally crying, real tears. I’ve been studying this for weeks and been confused for weeks. You just took everything I thought I knew and made it all make sense

I love that he talks fast. I can quickly take in much more information and he keeps me from getting bored.

I used to hate these videos back in high school because my teacher used to show these instead of slowly introducing and teaching the topic, which made every student feel overwhelmed and stressed. Now that I’m in college, these are so great for reviewing material because they go super in-depth and explain things very well! Great work!

If only high school teachers would be that exciting, and enthusiastic about the topic they teach...

This was really really helpful.
P.S. the neurotransmiters were too cute.

I realize most people would have trouble understanding due to how fast he is talking, but oh my god. As someone Hard of Hearing, it makes me SO SO SO SO SO happy to see that there are captions. They were incredibly helpful, there's almost never captions in the videos my teachers show their classes. Thank you so much.

this reminded me of an astronomy professor that used to say, "if you look at the sun, don't look at the sun"

You know Hank does a good job of explaining when your Biology professor in COLLEGE tells you to watch his videos.
