Hi agentcooper,
The Quant and Verbal sections of the GMAT are both adaptive, but that doesn't necessarily mean that the content that you face in the final few questions of the Verbal section will be 'hard' (nor that those questions will necessarily be 'harder' than earlier questions). In simple terms though, if you show a consistent ability to correctly answer questions, then the Exam will adapt to you and provide you with (generally-speaking) more difficult questions as you progress through it.
GMAT assassins aren't born, they're made,
