I use youtube to watch tutorials on subjects I am interested in. Some tutorials contain multiple videos and I need to watch them in the right sequence. However many times its hard to find the right sequence of videos (lesson 1, lesson 2, lesson 3). I need to search for titles that contain the sequence number ("Data science for beginners - 1", "Data science for beginners - 2") to find all the parts. Does anyone else face this problem? How is this being solved today? What are the alternatives?
