NDA 2 2026 Important Maths and GAT Topics with Highest Weightage

Every year, thousands of aspirants appear for the National Defence Academy (NDA) examination with the dream of joining the Indian Army, Navy, or Air Force. While many candidates work hard, only a small percentage are able to secure a score that places them comfortably above the cut-off.

One of the biggest reasons behind this gap is the preparation strategy. Many aspirants spend months studying the entire syllabus without understanding which topics actually carry the highest weightage in the examination. As a result, they invest too much time in low-priority areas and miss out on easy scoring opportunities.

If you are preparing for NDA 2 2026, your goal should not simply be to complete the syllabus. Instead, your focus should be on mastering the NDA Maths important chapters and the NDA GAT important chapters that have consistently appeared in previous examinations.

NDA 2 2026 Exam Pattern: Why Understanding Weightage Matters

Before discussing important topics, let’s quickly understand the exam pattern.

Paper	Questions	Marks
Mathematics	120	300
General Ability Test (GAT)	150	600
Total	270	900

The Mathematics paper carries 300 marks, while the GAT paper carries 600 marks. Since the GAT section contributes two-thirds of the total written marks, candidates cannot afford to ignore it.

The smartest NDA aspirants are not necessarily the ones who study the most hours. They are the ones who understand topic weightage and prepare accordingly.
