Chapter 7: This chapter was pretty easy and went well for the most part. I ran into an issue in the first tutorial where I could not select the outlines of buildings, but after resetting I was able to complete the tutorial without issue. I encountered no other problems with this chapter. 
Chapter 8: Didn’t have any issues with the tutorials for this chapter, the only thing that went wrong was in the second tutorial the computer froze while running the geocoding addresses tool. I waited several minutes for it to unfreeze but ultimately had to power off the computer and restart the tutorial. Afterward, I encountered no issues in this chapter. 
Chapter 9: I only had to restart tutorial 3 in this chapter due to making a mistake early on, I think it was with the spatial join tool. Other than that, there were no issues in this chapter. I feel like after completing all these tutorials I am getting a better understanding of how tools work and what they can be used for.
