I've used Code.org for the past 2 years and I am liking the changes in courses A-F. The intro videos for A and B are great. I actually showed my 2nd graders Stevie's video too. Great message and connnects perfectly to the work they will be doing.
Course D (3rd) has 2 collects in level 12 and the teacher solution shows that it requires 4 but they're limited to 2.
Course E (4th) has gotten the best feedback because it starts with the game creator with Star Wars. I would have loved to see that in Course F with another spin to it.
Course F (5th) has obsessively been the most challenging for my students but that's expected since it is the last course. They are getting frustrated and I see many students not seeing the point.
I will continue to provide feedback though
