It's more that certain words should be red flags to get you to think in a certain direction rather than guiding you down that path. "At least" is a great example of this since it is a great chart signifier but not a foolproof one.
Don't foolproof in the curriculum and stop doing all the problem sets. Do only enough to get a feel for the topic and then save the rest for your PT phase to shore up any weaknesses.
If you look at the games menu in the app you can see all the categories in one place. Best thing to do is just foolproof those games and watch the videos.
