Pandas course - don't pay for it! This is about the Pandas course. It said it would be about 4 hours and I would get a certificate at the end. I know a thing or 2 about database languages and the pandas course was a very big disappointment. Don't pay for it, just do it for free online. It took me about an hour, the "exam" was regurgitation via multiple choice. Nothing about merging or filtering data or doing any useful analysis. Very basic. I really regret paying.

It's useful as a reference tool for web… It's useful as a reference tool for web programming.

PivotTables tutorial was written by a drunk The excel tutorial was mostly great, until you get to pivot tables. That section was clearly written by a drunk person. Beside the constant typos and sentence incoherence there are no examples on how to actually make and use a pivot table, it doesn't tell you where any of the menu options it points out are, it is bafflingly unclear about everything because drunk typing, it doesn't give you a sheet to copy and practice making on your own like every other lesson - This was the tutorial I was waiting to get to and W3schools completely blew it. Does anyone double check this crap before they upload it? Apparently not. Don't give these people money, or clicks.
