You’re right it’s good to prepare young people for challenges. Still, that should mean challenges that would come up anyways, not artificially making things more difficult.
It’s good to know how to read an analog clock, just like it’s good to be able to read cursive. But both of them are outdated and aren’t inherently required in day to day life. Inserting them into a testing situation that’s meant to test something else is creating an unnecessary challenge.
