Just finished watching all 40 episodes and wanted to give a quick shout out to the graphics team Thought Cafe, the animations and graphics are awesome and I love all the references!

[quinnross]

I love how on 4:46 he casually threw in "Okay? Okay." from the fault in our stars reminding me of that painful, painful book made by his brother

[somethinghhh]

made a 96 on my psych final because of this series... thank you all!!!!

[TheFireflyGrave]

That's the end of the series?  I wasn't psychologically prepared for this.

[xyZora]

I truly hope you guys do a psycology crash course part 2 in the near future! I love learning about psycology and your videos are excellent resources to understand the basic aspects of psycology.

[MegaFenix]

Dear Hank, please make a sociology Crash Course. Thanks

[nunyabuziness]

LOVED THE BREAKING BAD REFERENCE taking my exam next month and I can’t even express how good crash course has been for me, hope anyone looking for a real place to continue studying outside of school ends up here. Thank you Hank.

Bummer that the Psychology course is coming to an end. I would love to see a series on educational psychology-- many viewers of Crash Course are teachers or college students on their way to becoming teachers. Please consider it! Love you guys! 

[saltaiaw]

Am I the only one learning this for fun and not because of any tests?

[gravitywave]

And one cram of all 40 weeks squeezed into the two days before the AP Psychology exam finally comes to a close. Thanks to Hank, I am feeling pretty good about a five.

Thank you for this awesome program you put on, whether or not I am a bit late

[ToxisLT]

done, all 40 in one lazy sunday - can I print my degree now?:)

[leahfrazier]

Dear PBS you literally are the best online study tool Ive come  thus far online. You make learning for me exciting and fun, sounds cheesy but its that simple. I'm an ART major so the animation you use is very stimulating in your lectures. A+ I love this guy.

[Thiefree]

The bystander effect has always really concerned me. I mean, I would have said something, but nobody else seemed that worried, so...

[youcefsb]

THANK YOU Hank and all Crash Course Team, that's the least thing someone can offer you back, Thank you so much (after finishing History, Philosophy, Economics, Sociology and Psychology)..

[andresymedio]

I have come to love these videos in a way I can't even explain. Every night I'd get to the PC, check the youtube page and see if there was a new video on the psychology course. These videos have somehow become a big part of me, they have been very useful for my college studies, but not just htat, they have helped me to understand people better, and of course to understand myself too. 
I'd like to deeply thank you for doing this, Can't believe it's been almost a year of Crash Course psychology!

[mattiasfagius]

I just wanted to say thank you to Hank and Crash Course for the psychhology-series! I have seen the 40 episodes and gained lots of insights about both myself and others, as well as opened myself to the world of psychology. Most likely I´ll watch many of these episodes again to understand things better, and maybe read more in chosen subjects to deepen my knowledge and understanding. To publish such great content for free like you do on the internet is a truely awesome thing, keep it up Hank and John and all the others working for this project! Greetings from Sweden!

[Steelerbacks]

Thank you for all the psychology help! I watched all 40 videos and I found them to be good refreshers of old information as well as great sources to new info. With the AP exam tomorrow, this was exactly what I needed, and now I feel prepared to get a 5!

[cassiedunford]

Hank you have to continue this series!! I’ve been using it since it began for my university exams! Today’s exam is Social Psychology and Just watching a couple of relevant videos before the exam really jogs the memory of the revision I’ve already done!

[alannar.]

Thanks for basically giving me all the sources I needed to prove that Lord of the Flies is an inaccurate model of society for my research paper. You guys are the best.

I have loved these. I am taking psychology at A level here in the UK with the hopes of getting involved in counselling psychology as I have experience with mental illness (I have OCD) and I want to help people who struggled like I have with mental health. These are so fascinating and I love them, I also get a nice feeling when you mention something that I recently learned in a lesson about which is funny :D
