As the name suggests, What Can I Learn Today (or, wcilt) is a repository of some uniquely curated Courses. This is not a marketplace for Courses but those that I am personally passionate about. You may not find hundreds of Courses here, but the ones that you do find will hopefully be of interest. 
Do visit https://wcilt.com to take a look at the Courses on offer now and some that will be coming up shortly. It takes a lot of time, and energy to develop the Courses and I hope that you will enjoy what you see.
On the YouTube channel the videos that are part of the various Courses are grouped under specific playlists. However, the Courses are far more structured and you might find it easier to take a Course to take full value out of these videos.
Happy learning!!!
