1. Is this iteration of Are You Smarter than a 5th Grader? The same across all platforms, and does the Switch version have an achievement equivalent in-game?

2. Does this game have any permanently missable content? I don't want to assume it doesn't only to find out when my only option to try again is restarting the entire game?

3. Does it have any promotional content or bonuses obtained by having save data from a different game?
