I agree with norma. If you mean the weekly planner, I think he meant watch the whole thing during the week. In my opinion it is good practice with many of these lessons to just watch the whole thing and take some notes here are there first. After that, every now and then, you can watch specific parts to go over things you may not have fully grasped.
This will also depend on what kind of learner you are, I know some people may be intimidated by doing something that seems big and then procrastinate. But I see watching the whole video kind of like scanning a chapter quickly to get an idea of what I'm getting into and then reading it taking my time (watching the lesson step by step and doing practice and assignments as I go)
