TADA credit

[NapoleonInRags]

TADA question here. I'm doing the Google IT Support Professional course. I've finished the intro and Course 1.

Just started Course 2. At the start of the course, it read:

You can review videos, readings, discussion forums, in-video questions, and practice quizzes in the program for free. However, to access graded assignments and be eligible to receive your official Google IT Support certificate, you must:

• Pay the course certificate fee, or apply and be approved for Coursera Financial Aid.
  

I thought this TADA/Coursera course was for free?

Also, they wrote something about having to upload a legal ID, did everyone who took TADA on DF have to do this?

Thank you..
