i have complete the requirement to be done but there is no complete sign what should i do?
Hi @usman_ahmad2 ,
All the labs for C1 week1 are not graded labs, so there is no submission button for them. Only graded labs have submission button. You would see a blue rectangle button on the top right hand side when your jupyter notebook is opened if the assignment is a graded one.
Just move on to the next week of the course materials.
