Stuck after lesson 2

I am stuck at the end of lesson 2 and can’t proceed to lesson 3. I just always get send to a sign up for pro page, I thought this course was free as long as you don’t want the exercises?

Hey and welcome to the forums!

I believe it’s the lessons themselves are free, but the projects, quizzes and extra resources are not. Would you mind sharing a link to exactly what it was you’re trying to access?

Seems it was just a temporary block to the next lesson to encourage a pro membership or a bug. I was just using the course regularly and used up next at the end of lesson 2.
It was just the regular C course I was accessing
