Most candidates spend 4–10 weeks in dedicated board prep after graduating. The most effective method combines: (1) reviewing a comprehensive FNP review book for content gaps; (2) answering 50–100 practice MCQs daily with rationale review — this is the single highest-yield activity; (3) taking full-length timed practice exams in the final 2 weeks to build endurance. BlitzGrok focuses on step 2 with adaptive MCQ sets that identify your weakest domains and serve more questions in those areas. Aim for consistent practice over passive reading.
