"Jsi chytřejší než před týdnem?"

[Doug-S]

The "correct" answer is so wrong in so many ways. It asks me if I'm smarter than the ambigious "one week ago." I realize how it would be interpreted in casual conversation, but it doesn't make the grade in written communication.

Absolutely agree. It should be smarter than you were a week ago, which is not accepted.

Fun fact: The game show "Jsi chytřejší než páťák?" (Are You Smarter than a 5th Grader?) exists in the Czech Republic (e.g., see https://www.youtube.com/watch?v=HuyKG35o5qY ).
