This lab requires a little more critical thinking skills than lab 1. I've done exercises like this before in a database setting. I think I had a difficult time with the rearranging letters question because I needeed to go back to see how I can write it concisely. The longer my pipes got, the more likely I was to making mistakes. I did ask my group mates for help and the discord chat. I am getting more comfortable with that.
