What helped me most was treating Step 2 as a decision-making exam rather than trying to memorize another textbook. Use UWorld during clerkships or dedicated, but review each block for the clinical pivot: what finding changes the diagnosis, what makes one test appropriate now, and what determines the next management step.
CMS forms are valuable because they teach NBME wording and priorities. I would complete them by specialty, then use NBMEs at intervals to identify whether the problem is content, question interpretation, timing, or changing correct answers. Keep a brief error log organized by reason for the miss rather than copying long explanations.
For an average student, consistency is more useful than an extreme daily question target. A strong routine might be one timed block, thorough review, and focused repair of one weak topic. As the exam approaches, spend more time on NBME/CMS patterns, ethics, quality improvement, screening, and risk factors. Feel free to message me if you want help adapting that framework to your clerkship schedule or target score.
