How to Crack NDA Exam in 1 Month: Smart Preparation Strategy for 2026

The National Defence Academy (NDA) exam demands a strategic approach, especially in the final month, followed by a focused plan covering exam patterns, essential preparation strategies, and subject-specific advice to maximize your score. Understanding the exam structure, practicing effectively, and mastering time management are crucial for success in this competitive examination.

NDA Exam Pattern

The NDA exam is scheduled for April 12th with a total of 900 marks. It comprises two papers:

Mathematics Paper:

• 120 questions

• 300 marks

• 2.5 hours duration

• Negative marking: -0.83 per incorrect answer.

General Ability Test (GAT) Paper:

• 150 questions

• 600 marks

• 2.5 hours duration

• Negative marking: -1.33 per incorrect answer.

Instructional Advice:

Think carefully before answering; some questions must be left unattempted. Historically, the highest cutoff has been around 360-370 out of 900, emphasizing that attempting all questions is not necessary. A strong start significantly increases your chances of making the merit list.

Subject-wise Strategy (Last One Month)

Success in the final month hinges on a core formula: Revision, Practice, and Mock Tests.
