For most students, NBDE Part 2 is considered more challenging than Part 1 because it focuses heavily on clinical application and case-based reasoning rather than straightforward recall. While Part 1 tests foundational sciences like anatomy, physiology, and biochemistry—mainly through factual and concept-based questions—Part 2 requires students to integrate that knowledge into real-world clinical scenarios, covering subjects such as operative dentistry, prosthodontics, and patient management. The testing style in Part 2 emphasizes problem-solving, diagnosis, and treatment planning, which demands not just memorization but also critical thinking and decision-making under time pressure. This shift from theory to practical application makes Part 2 feel tougher and more complex for many candidates.
