The Combined Defence Services (CDS) Examination, conducted by UPSC, is one of the most prestigious gateways for joining the Indian Armed Forces. Every year, thousands of aspirants dream of wearing the uniform and serving the nation by joining Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), or the Officers’ Training Academy (OTA).
Among these, OTA (Officers’ Training Academy) is slightly different from IMA, INA, and AFA in terms of eligibility, exam pattern, and preparation strategy. If you are aiming to crack the CDS exam with OTA as your preference, your preparation must be focused and aligned with the demands of this academy.
At THE LAKSHYA ACADEMY – the best CDS coaching in Delhi and India, we specialize in guiding students for both written exams and SSB interviews, and over the years, we’ve observed how OTA aspirants must adopt a slightly different strategy compared to IMA/INA/AFA aspirants. Let’s break it down.
📌 Understanding OTA in CDS Exam
Before diving into preparation, it’s important to understand what makes OTA different:
- Eligibility: Both men and women can apply for OTA, unlike IMA/INA/AFA which are male-dominated.
- Age Criteria: OTA has an upper age limit of 25 years, while IMA/INA/AFA is usually 23–24 years.
- Training Duration: OTA provides 49 weeks of training, compared to 18 months at IMA and INA, and 74 weeks at AFA.
- Written Exam Pattern:
OTA → 2 Papers (English and General Knowledge)
IMA/INA/AFA → 3 Papers (English, General Knowledge, and Mathematics)
👉 This means Mathematics is not required for OTA aspirants, which directly changes the preparation approach.
📌 How OTA Preparation Differs from IMA/INA/AFA
1. No Mathematics Paper
One of the biggest differences is that OTA candidates do not have to attempt the Mathematics paper.
- Focus areas shift to English and General Knowledge only.
- However, this doesn’t mean OTA is “easier.” Since Mathematics is excluded, the competition for OTA is tougher in English and GK because the marks of these two papers alone decide your written exam merit.
2. English Preparation for OTA
For OTA, English plays a decisive role. The paper is designed to check your grammar, comprehension, vocabulary, and sentence formation skills.
Tips from THE LAKSHYA ACADEMY experts:
- Build a strong command over grammar rules (tenses, voice, narration, articles, prepositions).
- Practice Reading Comprehension daily.
- Improve Vocabulary through newspapers, editorials, and word lists.
- Attempt previous year CDS OTA English papers to understand question trends.

3. General Knowledge Preparation for OTA
The GK paper covers History, Polity, Geography, Economy, Science, Defence-related updates, and Current Affairs.
How OTA aspirants should approach GK:
- Make current affairs a daily habit. Read The Hindu, PIB, and monthly magazines.
- Revise NCERT books (6th–12th) for static subjects like History, Polity, Geography, and Science.
- Focus more on Defence-related current affairs, as questions on missiles, exercises, and awards are common.
At THE LAKSHYA ACADEMY, we conduct special current affairs sessions and provide monthly notes for quick revision.

4. Cutoff Trends for OTA vs IMA/INA/AFA
The OTA cutoff is different from the other academies since Mathematics is not part of the exam.
- For example, if the cutoff for IMA/INA/AFA is around 120–130 marks, OTA cutoffs usually lie between 90–100 marks.
- However, since only two papers decide the merit, scoring high in English and GK is crucial.
5. SSB Interview for OTA
The SSB interview process is the same for all academies, but OTA aspirants are often evaluated for their short service commitment and leadership qualities.
- Focus on communication skills, confidence, and problem-solving ability.
- At THE LAKSHYA ACADEMY – the number 1 defence coaching institute, we provide complete SSB training, mock interviews, group discussions, and GTO task practice to prepare you for success.
