NDA 2026 Preparation Strategy – Complete Guide for Aspirants
The National Defence Academy (NDA) exam, conducted by the Union Public Service Commission (UPSC), serves as the gateway for young aspirants aiming to join the Indian Armed Forces. This prestigious examination opens doors to training at the NDA in Khadakwasla, Pune, leading to commissions in the Army, Navy, or Air Force. Given the rigorous selection process, an effective NDA 2026 preparation strategy is essential for success. Starting preparation early can help build a strong foundation, especially since the NDA exam is held twice a year—NDA I and NDA II. The process involves a written examination followed by the Services Selection Board (SSB) interview and medical examination, testing both intellectual and personality traits.
Official NDA 2026 Exam Overview
The NDA 2026 exam is overseen by UPSC, ensuring a transparent and merit-based selection. The selection comprises three main stages: the written exam, SSB interview, and medical examination.
The written exam consists of two papers: Mathematics (Code 01) worth 300 marks and General Ability Test (GAT, Code 02) worth 600 marks, totaling 900 marks. Each paper lasts 2½ hours. The SSB interview carries an additional 900 marks, making the overall process highly competitive.
A key feature is the negative marking system: one-third (0.33) of the marks allotted to a question are deducted for each wrong answer. If multiple answers are marked for a single question, it is treated as wrong. Unanswered questions incur no penalty. All questions are objective-type, and the papers (except the English part of GAT) are bilingual in Hindi and English.
