Shivangi Singh says:

My bio teacher is well-known for not paying attention to any of her classes except chemistry, and then at the end of the year, giving out candy to all of her other classes and apologizing for being a shitty teacher. Of course, that does nothing to raise my grade in her class. But these videos do. Thanks so much y'all for helping me understand this flipping course.

stellarfirefly says:

I'm kinda missing these older-style Crash Courses. While I do understand and appreciate the advantages of the more scripted, focused, and professional format these days (end of 2015), the less formal manner of these older videos does have a kind of warmth and a friendly charm, while still being highly informative, well-researched, and reasonably short.

Louise Bee says:

Unlike apparently a lot of people in the comments, I am not watching this for school- just for my own education. I love how Crash Course mixes education with comedy. Thank you very much for this video and. of course, every other video made. You are all awesome and helping people become just that little more knowledgeable. PS. "All for me" had me laughing for a worryingly long time hehe

Eagle 4 says:

What are the books that Hank is reading in the Bio-lography. They seem interesting.

Dougie Boxell says:

really? come on mate, egg and peanut butter can't be that bad
i would argue that the peanut butter would be very bad for health. and not just cause of the sugar.

can you do a video on trans fats? everyone knows that they're bad, but i have no idea why, especially given that after looking into fats, saturated fats are not the devil everyone makes them out to be.
i am yet to find any decent, in-depth content on trans fats.
