Some of the best instruction I've ever received (and I have too many degrees). These courses are intensely practical. Making sure people understand the theoretical underpinnings comes second to making sure people can actually use DL/ML software for their own purposes.

The site could use a reorganization, though. Jeremy and Rachel have created a number of courses, but you have to hunt through their YouTube and fast.ai forum comments to find all of them. So much good content should not be buried!
