This was fun!
It took me 3 tries to get 100%, but I got there! I started with the Hollywood Challenge, then the Broadway Challenge, and finished up with the Great Wall Challenge. Honestly, I think I could have gotten 100% on the Broadway Challenge, but I was going too fast, and didn’t read the feedback between tries carefully enough. This means my lower scores reflected a tendency to rush through things, which may not reflect my understanding of keyword searching per se, but does identify something to work on at the reference desk.
