What is the Exam?
The Combined Defence Services (CDS) examination is a premier national-level competitive exam conducted biannually by the Union Public Service Commission (UPSC). It serves as a gateway for graduates seeking entry as commissioned officers into India's elite Armed Forces, including the Indian Military Academy (IMA), Officers Training Academy (OTA), Indian Naval Academy (INA), and the Air Force Academy (AFA).
Among the three papers in the CDS entry (General Knowledge, Elementary Mathematics, and English), the English language paper is universally acknowledged as a critical rank booster. Vocabulary-based questions—encompassing synonyms, antonyms, idioms and phrases, cloze tests, and spotting errors—form nearly 40% to 50% of this paper. Succeeding here requires a systematic command over high-frequency words, which is precisely why we provide this targeted resource.

Preparation Strategy
Mastering the high-frequency vocabulary list demands more than simple rote memorization. Our expert faculty at Exam Bhai recommends a multi-layered strategic approach:
1. Root Word Memorization (Etymology)
Learn words through their Greek and Latin roots. For example, knowing that 'Bellum' means war immediately unlocks words like belligerent, bellicose, and rebellion. This allows you to deduce meanings of unfamiliar words during the live exam.
2. Context-Driven Reading
High-frequency words stick better when you see them in action. Spend 30 minutes daily reading editorials from The Hindu or The Indian Express. When you encounter a word from our PDF, note down how the author applied it in a live sentence.
3. Rigorous Evaluation
Testing is the bridge between learning vocabulary and scoring marks. You must actively test your retention under strict simulated environments. You can easily access high-yield practice resources and practice free mock tests for CDS 2027 on Exam Bhai to assess your progress daily.
Cut-Off Trends
As verified from official historical archives on upsc.gov.in, the written exam cut-offs fluctuate based on paper difficulty and the total number of applicants. The following historical estimates showcase the typical trends out of the total written marks:
| Academy Preference | Written Cut-off Range (Out of 300 / 200 for OTA) |
|---|---|
| IMA | 130 - 145 Marks |
| INA | 120 - 135 Marks |
| AFA | 145 - 160 Marks |
| OTA (Men & Women) | 100 - 115 Marks |
Because the English paper contributes up to 100 marks of these totals, scoring 70+ in English significantly eases the burden on your General Knowledge and Mathematics preparation.
