So much info at once. Just wondering, why not go through uses of features one by one with an example case like in the Beginner course?
There isn't really one project that would need all of these settings, and certainly not a beginner project. You don't need to memorize everything here! Just have the fact that these things are possible somewhere in the back of your mind so that you can look it up and get a refresher whenever you need it. Also, mess with them out on your own after the video. That will help you really solidify what can be done and is why the videos are grouped into related subjects and areas like they are.
Hope that helps. Happy modeling!
