Jarrett said: As I stated yesterday, this is the ONLY course I want to take. I took a different approach on these, I elected not to look at any notes and just go off of the top of my head memory wise. It worked it great in quiz 2, not so well in quiz 1 and 3, but that's the type of learner I am. When I do something wrong and go back and realize what I did incorrectly I seem to not make that same mistake going forward to often. The diagrams showed me where I made my mistakes and I have a much better understanding for things going forward. It's nice to always be able to look back on these charts, videos and quizzes and I made sure to document every step of 601 and 602 while printing them off for future endeavers. Thanks professer!

William said: The practical examples provided a challenge and a worthy exercise to complement the previous course. The Project 3, worksheet page 2, building #4 diagram has a weak line between a section of units that was initially difficult to discern.
