As a beginner, I started with HTML but haven't completed it. I moved over to 'R' but I was only able to unlock first lesson. Y?

Choose your language, and stay focus at that language

The next lesson unlocks when having completed the previous lesson.

So are you saying it's because I'm not done with HTML???

Bcos after completing the first lesson on 'R', the next lesson is still locked 😭😭

*the previous lesson of the same course. You need to do the very first lesson of a course first to unlocks the second one.

If you have completed the lesson, there should be a green ✅

Lisa , Thank you so much❤️❤️ It just works

Thanks

I think that's a error.
