The only caveat I have with the course is the impossibility to audit and do the assignments (don't care about submitting them, but having access to the prompts would be nice). Luckily, Dr. Chuck has made those available somewhere else. That said, it builds nicely on top of the previous courses and increases the difficulty in a gradual manner. I would say here you will find to start going back and forth making sense of the earlier lessons and combining what you learned to make the assignments come to life. Nevertheless, it is possible to do that, and you will learn that the first two were indeed a good stepping stone for the ones to follow. Thank you, Dr. Chuck!
