GROW: The Book

I find this to be confusing. I do a video, take the quiz, and it shows up as if nothing happened.
@Bonnie Nikki @Nikki Follis might be able to help with or explain this. I'm not sure and don't want to give you the wrong answer.
Good explanation of double digging and why. I have been basically hearing no dig/ no till as the way to keep from disturbing the soil layers. This keeps the soil layers in their proper positions. We have a lot of clay and hard-pan in our soil which needs be be broken up and have nutrients introduced.
I am double digging my beds, my soil really needs it as it is very hard and has lots of clay. Should be ready for winter crops which I need to get in very soon.
I've read about double digging before, but had never seen a demonstration like this. It really helped it make sense!
