I am currently studying the Data Science Certificate track of DataQuest. Unfortunately, it is necessary to begin from the very beginning on python to complete this certificate, while I already have more than 10 years programming in science and a few years in python specifically. I have included my progress so far below. I am doing this part time while tutoring for a living. 

I did not complete the Google Data Analytics certificate through Coursera due to the extra cost of using Big Query, which was more than $500/month.
