How can I bookmark a lesson, in other words, put in favourites

Hi Islam, Thanks for reaching out! At this point we don't have a way to achieve that inside the platform. However, you can create bookmarks on your browser. Here is a detailed guide on that: https://support.google.com/chrome/answer/188842?co=GENIE.Platform%3DDesktop&hl=en What I usually do is to create folders and subfolders with my desired bookmarks. For instance, you can have a folder: 365 Data Science, which has a subfolder for each course.  Hope this helps! Best, The 365 Team
