CDS exam pattern
CDS is a pen-and-paper exam with objective (MCQ) questions. Each paper is 2 hours and 100 marks. Wrong answers cost one-third of the marks for that question.
| Academy | Papers | Total |
|---|---|---|
| IMA, INA, AFA | English (100) + General Knowledge (100) + Elementary Mathematics (100) | 300 marks |
| OTA (men and women) | English (100) + General Knowledge (100) | 200 marks |
After the written exam, shortlisted candidates face the SSB interview (5 days: 300 marks for IMA/INA/AFA, 200 for OTA), then a medical examination. Final merit = written + SSB.
CDS syllabus in short
- English: reading comprehension, spotting errors, sentence improvement, synonyms/antonyms, ordering of sentences, fill in the blanks, idioms.
