How to Improve English for NDA/CDS- Sanjeev Thakur Sir’s Vocabulary & Grammar Framework
How to Improve English for NDA/CDS: Sanjeev Thakur Sir’s Vocabulary & Grammar Framework Table of Contents Every year, thousands of NDA and CDS aspirants lose their rank not because of Maths or General Knowledge, but because of English. It’s the one section students postpone the most and understand the least. If you have ever asked yourself “why do I keep making the same mistakes in English no matter how much I study,” this guide on how to improve English for NDA/CDS is written for you. At Cadets Defence Academy, our founder and faculty of English, Sanjeev Thakur Sir, has spent over a decade teaching English specifically to defence aspirants in Dehradun. In this detailed guide, we break down his complete vocabulary and grammar framework, step by step, so you can apply it starting today — no matter which stage of preparation you are at. Why Does English Deserve Equal Priority in NDA/CDS Preparation? Most students treat English as a “scoring section” they will revise later. This is one of the biggest preparation mistakes we see at CDA. Here’s why English deserves the same daily attention as Maths and GK: It carries substantial marks in both the NDA English paper and the CDS English exam pattern, and a weak score here can pull down an otherwise strong overall rank. Unlike Maths, English rewards consistency over cramming — a word learned wrong today will cost you marks even six months later if it isn’t corrected. Your performance in English directly reflects in your SSB interview, Lecturette, Group Discussion, and Personal Interview. Officers are expected to communicate with clarity, and the selection board notices this from the very first conversation. Comprehension and error-detection skills built for the written paper also improve how confidently you write your Personal Interview Officer forms and psychological test responses (TAT, WAT, SD). In short, English is not an isolated subject — it is a skill that supports your entire defence exam journey. NDA vs CDS English Exam Pattern: A Side-by-Side Comparison Before building any strategy, you need absolute clarity on what each exam actually tests. Here is a simple comparison table our students use as a quick reference: Feature NDA English Paper CDS English Paper Total Marks 200 100 Question Type Objective (MCQ) Objective (MCQ) Key Areas Tested Grammar, vocabulary, comprehension, cohesion, ordering of sentences Error detection, sentence improvement, synonyms, antonyms, comprehension passages Difficulty Level Moderate, tests foundational clarity Slightly higher, tests application-based grammar Negative Marking Yes Yes Weightage in Total Score Roughly 1/3rd of Maths + GAT combined Roughly 1/3rd of the written paper Best Preparation Focus Root-word vocabulary + basic grammar accuracy Error spotting + sentence-level grammar precision You can always verify the latest official weightage and pattern directly from the UPSC official website before finalising your preparation strategy, since exam patterns are reviewed periodically. Who Is Sanjeev Thakur Sir, and What Makes His Framework Different? Sanjeev Thakur Sir is the founder of Cadets Defence Academy and has personally guided English preparation for hundreds of NDA and CDS aspirants in Dehradun. What sets his teaching apart is that the framework isn’t borrowed from generic competitive-exam material — it is built entirely around the recurring mistakes Indian defence aspirants make: Memorising word meanings without understanding root structures, causing them to forget words within days. Learning grammar rules by heart instead of learning to apply them inside real sentences. Practising comprehension passages without any time discipline, which fails them badly on actual exam day. Ignoring spoken English entirely, even though it directly affects SSB performance later. His framework fixes each of these gaps through three connected pillars: vocabulary through root words, grammar through application, and comprehension through timed, disciplined practice. How to Build a Strong Vocabulary for NDA/CDS? (The Root-Word Method) “How do I remember vocabulary for CDS and NDA without forgetting it in a week?” This is the single most common question we hear in our classrooms. Random word lists don’t work because the brain forgets isolated information quickly. Sanjeev Thakur Sir’s vocabulary framework solves this using root words, which unlock multiple related words from a single concept. Step-by-Step Vocabulary Framework Learn one root word every day. For example, the root “bene” (meaning good) instantly connects you to benefit, benevolent, benefactor, and beneficiary. Prioritise high-frequency exam words that repeat across NDA English previous year questions and CDS papers, instead of rare words that rarely appear. Use every new word in a sentence immediately. This single habit converts short-term memory into long-term recall. Pair every word with its synonym and antonym, since both NDA and CDS test vocabulary in this exact format. Revise using spaced repetition — review Day 1 words again on Day 3, Day 7, and Day 21. This is what actually moves vocabulary into permanent memory. Sample Root-Word Table (Start Here) Root Word Meaning Connected Words Bene Good Benefit, Benevolent, Benefactor Mal Bad Malpractice, Malicious, Malnutrition Dict Say/Speak Predict, Contradict, Verdict Port Carry Transport, Portable, Export Spec See/Look Spectator, Inspect, Retrospect Vac Empty Vacant, Evacuate, Vacuum Following this vocabulary tricks for NDA exam approach consistently for three months typically builds a working word bank of 800–1000 high-utility words, which comfortably covers most vocabulary-based questions across both papers. How to Master Grammar for NDA/CDS English? Grammar is where aspirants lose the most avoidable marks, simply because they were taught rules without ever applying them. Sanjeev Thakur Sir’s grammar framework for competitive exams is built entirely on application, not memorisation. The Four-Step Grammar Approach Step 1 — Master the foundation first. Before attempting error spotting tricks for CDS, be completely confident in the basics: parts of speech for defence exams — nouns, pronouns, verbs, adjectives, prepositions, and conjunctions. Skipping this step is the number one reason grammar preparation collapses later under exam pressure. Step 2 — Focus specifically on tense and voice. A large share of error-detection questions in both exams comes from incorrect tense usage and active-passive voice errors. Dedicating focused practice to just these two areas alone noticeably raises your grammar score. Step 3
