The ideal preparation time to confidently clear the NBDE (or INBDE) typically ranges from 4 to 6 months, depending on a student’s prior knowledge, study habits, and available time each day. Students should begin by understanding the exam structure and creating a realistic, goal-oriented study plan that divides subjects into manageable weekly targets. The first phase (about 2–3 months) should focus on building a strong conceptual foundation using standard books and review materials, while the next phase emphasizes intensive practice with question banks and mock tests to simulate real exam conditions. Effective time management involves setting daily study blocks, incorporating short breaks, and reviewing difficult topics regularly to reinforce retention. Balancing consistency with focused revision ensures both depth of understanding and exam readiness without burnout.
