Bio final today. Good luck to everyone else who has one soon
-
The respiratory system is breath taking
-
It's depressing how a 12 minute video by these guys have taught me more than 3 years of high-school have
-
It's so weird, when I watch this I actually like learning... Wonder what my own teachers are doing wrong
-
This guy explains this 10 times faster than my biology techer in school does. This is why you should watch videos on youtube instead of staring at boring powerpoints and writing down notes while getting 5% of what the teacher just said!
-
5:36, for those guys who just needs the circulatory part... you're welcome
-
YOU JUST ENTERED MANUAL BREATHING MODE.
-
Hank and John, you guys are saving my junior year
-
Thank you so much for this! Much easier to follow than my textbook, and since my teacher doesn't actually teach, I guess this'll be how I learn from now on
-
You literally covered EVERYTHING on my test!
-
Biology test? Biology test.
-
Would love a CrashCourse on cardiac output and stroke volume!
-
I love these videos! The textbook my school has is super outdated and horrible about explaining things. My teacher has no strict curriculum-- he just randomly lectures on something kind of pertaining to the current chapter. These videos are an amazing supplement to my textbook. Hank, have you ever thought about teaching teachers on how to convey information in an interesting way? If the public school system took this kind of organized, quick, and entertaining way of teaching, maybe the US wouldn't be so low on the global educational totem pole.

Love these videos! I'm taking online biology courses for school so I do most of my studying alone. These videos are like my "teacher" lol. It sticks with me a lot more when someone else explains it.
-
This went over the equivalent of like 5 lesson in my biology class.
-
A video on Blood would be awesome! Covering the formed elements and plasma, and how blood is made and so on. :D Your videos are very helpful!!!
-
CrashCourse Biology always uploads on Monday!
-
My biology instructor showed this video in the class, and I just can pay attention to it! Great job, Hank! You made me, a student whose English is not his first language, understand it clearly in English without trying translation.
-
Im Dutch, so most of the things explained have a different name here, making it more difficult to understand everything. It's still surprisingly fun to hear what everything is called in English. Keep up the great work!
-
You are amazing :) Summarised 20 pages in 11 mins and my understanding of the topic has improved!
