As a Ph. D. student I started to study data science in Practicum, which is really amazing. The team and mentors are great and I see advancing. My intent is advancing much more and I advice this experience to any one who is serious and has intent to study data science.
The support team helps you when you need, community managers helps and here for you anytime when you feel stuck and your reviewers and mentors helps you to figure out problems.
Also the study is based on theoratical and practical structure. I feel I'm learning theoretical background while learning applicable data science.
My other focus is studying data science in Y-Data School.
Thanks Practicum team.
