In one specific sense, yes. Module 1 decides your routing, and routing decides your ceiling. A careless error on an easy Module 1 question can cost access to an entire scoring range, while a hard Module 2 question you miss costs one question. Students chasing top scores who drill only hard material have the priority backwards.
The practical inversion is worth stating plainly: for most students chasing a high score, the best use of the next study block is accuracy on medium-difficulty material, not more hard questions. Module 1 is where a preventable error costs the most.
