Question pertaining to the course I've enrolled for Python for ML course

Do I have to complete all the 6 courses to get the certification in 45 days? or do I have to just complete the Python for Data Science Module

Also, can I start working on the project " 1. Analyze your mailbox

Download all the emails in your inbox using GYB command line tool. Then analyze your emails using Numpy and Pandas and churn it to come up with various interesting insights."? after completing the Python for data science module?
