For the past month I’ve been working through Microsoft’s Data Science curriculum on edX. I’ve completed Dat101 (intro to Data Science) and Dat201 (Querying with Transact SQL). Next up is DS101X (Columbia’s Statistical Thinking for Data Science and Analytics).
So far the content has been great. The SQL course was surprisingly thorough. The Excel section of the intro course was mostly review, but even it had a few new things! The courses are completely free, though you can give them money for an official certificate.
