Hi,
I had a good question come up about the Mar. 2: Annotations on Elementary/Secondary/Advocacy articles found here.
https://softchalkcloud.com/lesson/serve/61RgvaowO05ZJI/html.
You do not need to annotate all of the articles. You only need do the ones that fit your context. For example if you are focused on elementary implementation, annotate the elementary articles.
Let me know if you have any additional questions.
Thanks,
Deborah
