I never got a chance to finish the lab… Only complaint so far would to allow this last week to go back and complete whatever you could not finish .
Otherwise … another good course …
Sorry you didn’t get a chance to finish the week, but I’m glad you like the course. 
You might want to post the request to be able to go back and finish after the deadline as a suggestion to the curriculum team, using the “Report an issue” tab on the bottom of the page. Good luck.
