"Awareness isn't the same thing as understanding."

I'm fairly confident that a definition of success is: Hank wore a t-shirt that I designed in a Crash Course video.

I have my AP Chemistry midterm tomorrow, and if it weren't for these videos I would probably fail. Thanks CrashCourse for taking the time to teach the world! :)

More organic chemistry and biochemistry please

[Kanrana]

My MCAT is already this weekend and since I graduated with a business undergraduate course, I have little to no background with Organic Chemistry.
Having watched your Organic Chemistry series, I have learned so much and even though there's a lot more to it, I'm finally understanding more of the notes I've been reading since I'm learning Org Chem all on my own.
Thank you so much for this series!

Will you make physics crash courses and math(calculus, trig) Thank you

[macacephalosaurus]

I took 3 chemistry courses this year, and you all have been a tremendous help. My eyes are getting watery here, knowing that crash course chemistry is over, but I will always be a fan and support in whatever ways I can. Thank you so much!

I'm so pleased that I found this channel! It helps me a lot with school work and is a fun way to revise. The only thing I would say is that he speaks so fast that it's hard to take in all of the information but other than that, I'm really pleased😊

I just hung my CC periodic table - I wanted to give it to my niece because it's cute and she could learn from a periodic table with clever creatures on it - but it's too awesome so I'm keeping it for me :)

My labcoat is in the mail...apparently...

Lastly - I think there should be an order-able diploma we can hang to show that we watched and vaguely understood EVERY episode :D

Congratulations! to all of you who just like me finished this crash course, DFTBA

[shankarnarayanan]

have anyone noticed that the number of views fell down from 2.7 million views in the first video to 466K in this video(almost 63 % decrease). This shows how many people procrastinate important and interesting things like this.

Is that a Professor Poliakoff shirt? That's from the "Losing fingers to Chemistry" episode, right?

[nels]

The cellular respiration equations (around 5:30) are not balanced. The products got switched. Easy mistake, no harm done. Just didn't see it as a comment so there it is.

[mrchangcooler]

He's wearing Professor Poliakoff :D

[chefkendranguyen]

Carbon is a boss. Good episode, Hank.

[aryanshetty]

Crash Course chemistry, is the best way to learn and revise, all i hope is they come up with Crash Course Chemistry Season 2. :D

[beirirangu]

you mixed up the charts in 5:18 and 5:26
CH₂O₂+O₂→6CO₂+6H₂O+ENERGY
C₆H₁₂O₆+6O₂→CO₂+H₂O+ENERGY

[jakegreenhalgh]

I started my year in chemistry predicted a D, now thanks to crash course my teacher thinks i will get an A, please don't let it end!!!

[XpertPilotFSX]

HE'S WEARING A SHIRT WITH THE PROFESSOR ON IT!
