Haven’t taken the real exam but what I’ve taken from the course seems really solid!

We’ll explained videos!
Only a few suggestions:
* Maybe have a couple of hints at the end of each module about common anti-patterns.
* In some of the videos there were takeaways at the end and not in others, takeaways seem very helpful as a summarization and reinforcement. Apply takeaways uniformly to the lessons.
* Create a separate course offering for more hands-on code development tasks for people who want to get their hands dirty with actually building these systems.
