Simple, and straight forward. Very easy to follow. The AppScript UI from Google has changed so much over the years, so for that part I kept exploring the UI till I understood where this or that was. Content is exactly what I wanted to learn. Great teacher

This is a very quick and easy to follow course. There are a few points where trouble shooting was required. It was good for me to problem solve, however it added 2 to 3 weeks of diligence and finding my own resources to complete the course.
