So this website here is astounding as a resource for learning. Headline is slightly misleading as yes it is free the first time with a paid option after. Here’s how it is, basically any topic you desire to learn about, they have people like in TED talks talking to you, but here the topics are usually less specific but they’re teaching you. There’s a schedule of lessons but when you watch them live they are free. After their airing then you must pay to view them, but the prices are not bad when you see the volume you get. They’re doing a lot of great free work in developing cultures where they waive the fees and are just trying to help people become more educated who haven’t had the chance.
