25 of 26 items complited

Hi all,

I see that I completed 25 of 26 items, but I can’t find that one that i haven’t done.
When I go to Chapter one it seems that all is done.
How can I find it?

Thanks in advance.


Check all the quiz and Labs are completed, if yes…kindly check if you missed any video without seeing…if you didn’t see it will highlight you in black…

It was the video thing.
Thank you very much!
