The Most Undervalued Data Science Course

You all know of Coursera's machine learning course and Andrew Ng's deep learning specialization. You even talk about fast.ai, These are all excellent resources to learn data science, but I want to make you aware of a lesser-known, yet superb, set of courses with which you can augment your knowledge in only a few hours. You've probably heard of Kaggle. You most likely have even participated in a challenge and maybe uploaded some kernels, but did you know Kaggle also provides data science education?
