That’s a great question. The best course really depends on what you want to learn.

For university-level learning, check out Coursera and edX. Most of their courses can be 'audited' for free. This gives you access to all the video lectures and reading material. You just don't get the certificate. It is a fantastic deal.

If you want to learn a practical skill, like video editing, coding, or even a new language, YouTube is a goldmine. Many creators offer complete, high-quality tutorials absolutely free of cost.

For building a solid foundation in academic subjects, nothing beats Khan Academy. It's completely free and very well-structured.

My advice? First, decide on a topic that truly interests you. Then, a quick search on these platforms will give you plenty of excellent options to start with. It makes the choice much simpler.
