I used to teach AP comp sci in the US, and my 95% of my students passed the AP exam. I use a combination of resources, but primarily used CS50 and code.org resources. The hardest part for me was differentiation. I would have students who could finish a semester of problem sets in a week, and students who couldn't finish one in a month. I think it depends on the goals of the course how you organize it. My goals were familiarity, comfort, and growth, so I had several tracks students could pursue, all of which would give them the same credit. Happy to share any knowledge or wisdom further.
