Posso fazer lives no youtube, resolvendo workshops do curso Full Stack Developer da freecodecamp, dentro do ambiente de estudos deles, ou terei algum problema quanto à questão de direitos autorais?
You can record yourself doing workshops from the full stack developer cert.
Have fun 
I’ve just started CSS and I’ve noticed that the contents of Relational Databases, Backend JavaScript and Python are all in “Coming Soon” status, as are all the module exams. Will I still get my certificate of completion?
When the remaining material is added for the course of this year, then you can claim your certification upon completion of the cert.
