help- which subreddit can I ask for YouTube channels that help me explain real-world examples in English?

Hey, I’m a non-native English speaker preparing for an English interview that tests reasoning and discussion skills.

I’m looking for YouTube channels that help me learn how to describe or explain famous historical or social examples in English. Basically, I know these events when asked about it, but I don’t know how to talk about them naturally in English or use them on my own to support an argument.

Which subreddit would be the best place to ask for recommendations like that? I was thinking of r/Advice at first but that sub didn't seem like it was a place to ask about academic stuff. Please help.
