Are all the certificates self contained? Or should some of them be completed before others further down? For example I am doing the scientific computing with python. Is it better for ease of learning to do this certificate before attempting the other related ones such as data analysis or machine learning with python?
Also, I did find the certificates to be fairly self-contained, though I can speak for the python certificates.
For the most part the certificates are intended to be done in order and are more of milestones along the way to the full stack certification, rather than independent courses. The Python curriculum is the odd one out.
