Reddit is the Internet’s best unknown resource of free online classes. The social media platform has countless forums and channels that cater to specific topics that help approximately 430 million monthly users — including you, the student in need of quick and useful info.

Unsure of where to look? Alex Brogan, who works in Web3 (an idea for a new iteration of the World Wide Web) crypto and growth marketing, tweeted about the best subreddits to advance your learning. Here’s what you can learn from them:

8 Reddit threads that offer the best, free online classes

1. r/explainlikeimfive

Are you struggling to explain or understand complicated concepts? With this channel, you can find answers to a wide array of deep questions — answers so well explained that even a five-year-0ld can get it.

For example, how do birds like falcons come out of a steep dive at speeds exceeding 200 miles per hour without being ripped apart by air resistance when they spread their wings? Try explaining the answer concisely to your friend. Now, do that to a five-year-old. 

2. r/coolguides

If Reddit threads are not enough to help you understand complex concepts, try this channel where you can find photographic reference guides to help explain the complexities of our world. After all, a picture is worth a thousand words. 

Here, you’ll find answers to questions like how trauma impacts the brain, ways to meditate, google shortcuts or even ways to identify different types of lights in the sky — and many more. 

3. r/changemyview

Want to change your view on certain perspectives? The r/changemyview channel can help you achieve that.

Discuss topics like the concept of “fear of missing out” or crime control in the US. Test your opinion, refine your points and find flaws in your arguments through these conversations. Who knows? You might learn a thing or two about a current affair — which can pay off, in the long run, to help you ace your job interviews. 

4. r/InternetIsBeautiful 

Need a place to find the internet’s best websites and tools? Try browsing through the r/InternetIsBeautiful channel.
