HI all

First time instructor here and racing the clock to finish producing my course on "BEFORE YOU LEARN TO CODE:  TECHNIQUES TO AVOID FAILURE AND DISCOURAGEMENT" 

I wanted to check whether i can update/edit/amend one or more videos after theyre published? I am experimenting with some delivery styles and i feel some of the content can be improved once i get some feedback from enrolled students. I'm hoping improving/replacing/updating individual videos is an easy process?

Thanks for you guidance!
