Queries Regarding Certificates

Hello . I have enrolled to the Machine Learning Specialization . I have already completed the Python Course and got the certificate for the same. I am yet to complete the ML and DL part.

My query is , Do we need to complete all the assignments that is 100% of the courses and Projects to get the certificate or is there any minimum criteria to get certified?

Kindly enlighten.

Regards,
