Hello, good morning, a question. Should the 3 evaluations be approved to achieve certification?
without failing one for some points I do not get the approval?
Exactly, you need to pass the three quiz in order to get the badge (that is NOT a certification, just a badge that shows that you attended a free online course).
Nevertheless, the main objective is to learn, the badge is just a way to encourage people to view all the videos and do the homework.
You have three chances of approving each quiz, so if you fail at the first attemp you should review the videos and do more practice before trying again.
