I was in the same boat…felt my design and map were okay, but was worried my description wasn’t going to be detailed enough. The problem I had with the description is that it’s permaculture! I could have written a book detailing every decision and highlighting every interaction between elements, but instead cut it off and handed it in last week. I remembered him saying that our design was not a test, but an exercise.
That being said, I received an email today congratulating me on completion of the course, saying that my design had been received, reviewed and assessed, and that I should receive my certificate in 10 days!
