Preparation Strategy for NDA and NA Exam within 30 Days

Are you aiming to prepare for the NDA/NA written exam in a short period, such as 30 days? While it might seem a bit challenging, with the right approach, it is possible to cover the essential chapters effectively. This article will guide you through the process, helping you to focus on the most crucial areas of mathematics and other relevant components.

Mathematics

The core chapters in mathematics that you should concentrate on for the NDA/NA exam are:

Integration (both Definite and Indefinite) Conic Sections Matrices and Determinants Statistics and Probability PNC (Permutations and Combinations) Relations and Functions Trigonometry

While these chapters carry significant weight, other chapters that are less frequently asked are:

Limits, Continuity, and Differentiability Differential Equations (D.E.) Complex Numbers 3D Geometry

To prepare effectively, start by reviewing the NDA syllabus and following the structured approach recommended below:

Step-by-Step Preparation Plan

1. Revise NCERT Books: Since most questions are based on NCERT level, focus on thoroughly solving the NCERT books for the mathematics sections.

2. Identify Important Topics:

Trigonometry: Approximately 10 questions (inclusive of height and distance, compound angles, and solutions of triangle). Prepare ITF (Inverse Trigonometric Functions) well. Coordinate Geometry: Around 10 questions (straight line, tangents, circles, and conic sections). Practice solving questions based on formulas. Probability: Simple 2-3 questions, Bayes Theorem 3 questions. Differentiation: Approximately 5 to 10 questions, focusing on log-based differentiation. Area under Curve: 2 to 4 questions, covering definite integrals. Quadratic Equations: 3 to 5 questions focusing on roots. Functions and Sets: 2 to 3 questions; additional practice might be needed.

Additional Tips

Language and General Knowledge (English and GK): Enhancing your English and General Knowledge can significantly improve your score:

Daily Reading: Devote time to reading newspapers to improve both English and General Knowledge. Aim to read daily for around 90 days. Study Science and Social Science: Go through the CBSE or your board's books for science and social science to build a strong foundation.

SSB Preparation: Although this section is not directly related to the NDA exam, clear preparation for the SSB (Services Selection Board) is beneficial as it contributes to overall eligibility.

Conclusion

Cheers on your preparation journey! Remember, with a focused and structured approach, 30 days can be enough to cover essential topics effectively, allowing you to perform well in your NDA/NA exam.

Happy studying!
