UPSC CDS/OTA 1 Exam Analysis 2026 Section-wise Difficulty, Good Attempts & Cut Off

One of the most competitive defence recruitment exams in India, the UPSC Combined Defence Services (CDS) Examination is applied by a lot of candidates each year for entry into Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA) and Officers Training Academy (OTA).

The CDS/OTA Exam analysis helps candidates to know about the difficulty of the paper, section-wise trend, the number of questions and distribution, expected cutoff, and the level of the competition.

Read below to get a detailed UPSC CDS/OTA Exam Analysis 2026 as reported by the experts and recalled by memory based questions & aspirants.

Detailed Section-wise Paper Analysis CDS/OTA1 was a comprehensive summary of each paper. The Section-wise analysis included a description of the subject's difficulty level, key topics, question pattern, and average performance of candidates. Using this analysis, aspiring candidates can get to know the exam pattern, check their performance, learn their strengths and weaknesses, and also make a better strategy to clear the other CDS/OTA exams in the future.

• Overall difficulty - All through, the paper turned out to be simple to medium level. All sorts of questions, i.e. factual, concept based as well as analytical questions were introduced in this paper which enabled judges to assess their ability to make timely decision making.
• Length of paper - Paper length was moderate and candidates were expected to keep a decent speed in order to try the maximum number of questions while maintaining the accuracy.
• Unexpected questions - A few surprising questions from defence affairs, international events, and less frequently tested topics challenge candidates and reward those with comprehensive preparation.
• Number of current affairs - This section occupied a major share in the GK section, which had issues relating to national events, international affairs, defense, economics, science, and government schemes.
• Static GK weightage - Static GK held a good share with questions relating to history, geography, polity, economics, science, and environment as per the usual trend of UPSC exams.
• Conceptual questions - There were conceptual based questions requiring application of fundamentals, information reading and ability to eliminate wrong options on logical grounds rather than rote learning.
• Time management - Ability of managing time properly was essential to attain speed with accuracy and allotted adequate time to each section and avoid some trick questions.
• Accuracy required - It is essential to maintain accuracy because of the negative marking and candidates have to opt for the right questions and have to minimize the guessing.

The CDS OTA 1 2026 English paper was rated easy to moderate in difficulty, making it highly scoring. Attempting about 70 - 80 questions with high accuracy would be considered a great effort among the total 120 questions.

• Grammar level - The grammar section was of moderate to easy difficulty level and consists of questions like spotting errors, sentence improvement, fill in the blanks, active passive voice and direct indirect speech. This section was a scoring one for students with a good understanding of grammar and is relatively less time consuming.
• Vocabulary standard - The difficulty level of the vocabulary section was moderate to high. It was inclusive of synonyms, antonyms, idioms, one word substitutions and use of words in context. A candidate with good reading and a habit of reading previous years' papers regularly, can answer well in this section.
• Reading Comprehension difficulty - The RC sections were moderately easy, with a few of them being moderate too. Reading comprehension tested the reading ability and understanding of candidates. A good reading habit will help the candidate to score in this section.
• Time taken - The candidates who prepare well are able to complete the English section in 35-45 minutes, with enough time left for review and re-checking.

This enables a candidate to attempt a good number of questions with accuracy.

• Comparison with previous years - The overall pattern of CDS English exam paper remains the same in terms of questions' distribution of grammar, vocabulary and reading comprehension. Overall difficulty level is similar but there were some difficult vocabulary and reading comprehension questions this year that may require a slightly better understanding than before.

Overall, CDS 1 2026 General Knowledge paper was assessed to be of moderate difficulty. This paper consisted of 120 objective questions. Most of the questions in the GK section were asked from History, Geography and Current affairs and Modern History and conceptual questions in Polity were trickier. For OTA, 50-55 correct attempts would be a very comfortable score.

• Static vs Current Affairs ratio - The paper had the standard CDS format, almost 75% of static GK and 25% current events, thereby rewarding candidates who have sound conceptual foundation in their preparation coupled with routine practice of reading newspapers.
• Defence questions - Questions in defence segment pertained to military exercises, indigenous missile systems, armed forces commands, defence organisations, ranks and latest in the country's defense sector.
• International relations - Questions covered India's relations with major countries, G20, BRICS, QUAD, neighbouring nations, international organisations, and significant global diplomatic developments from recent months.
• Government schemes - In the government scheme section questions focused on awareness of flagship welfare programs of the central government and social schemes, Digital Initiatives, financial inclusion, healthcare missions, and recent government initiatives.
• Economy - Economy questions included inflation, banking, RBI functions, Budget highlights, taxation, GDP, fiscal policies, and important economic indicators affecting India's financial landscape
• Awards - This topic covered questions on national honours, Nobel Prizes, major international recognitions, civilian awards, prestigious appointments, and achievements of prominent personalities across different fields.
• Sports - Questions were asked about top international sport events, individual gold medallists for India, venue for events, games and records, and individual sport achievements of the past year.
• Science - Science MCQs tested the understanding of the fundamentals of Physics, Chemistry, Biology, space technology and exploration, biotechnology, common use science, and the latest technology trends applicable to the competitive exams.

• Calculation intensive - Moderately calculation-intensive. All arithmetic questions and mensuration were calculative and required 2 to 3 calculation steps, but lengthy computations were limited.
• Formula based - Yes, about 60% to 65% of the paper was based on directly using the standard formula and mathematical concepts.
• Time consuming - Those with good command on basic fundamentals could have finished the paper on time. The only area which devoured most of the time was long calculation parts (arithmetic).
• Number of lengthy questions - Approximately 6–8 questions were relatively lengthy, mainly from arithmetic, algebra, and mensuration, requiring multiple calculation steps.

There are just two papers in the OTA exam; English and General knowledge. However there is no math paper unlike the one for IMA/INA/AFA. Thus for candidates without a science/maths background, the OTA exam is a favourable one, as more importance is given to language and general awareness about the world around us.

Overall the level of OTA paper is moderate, where English paper was of medium difficulty level and GK consisted of a good combination of static GK and current GK. With respect to IMA/INA/AFA examination, OTA examination was easier as there is no Mathematics examination which means candidates can give a large amount of time in optimizing their scores in English and GK papers.

Good attempts give a fair idea of the questions answered at a very good level of accuracy (85-90% and above). The number required could also depend on the difficulty of paper and estimated cut off, generally having a very accurate number of attempts is much better than too many of them, due to the negative marks of one third.

Note - These final cut-off ranges are derived on the basis of the trend of CDS 1 2026 UPSC exams, and it requires the candidates to secure at least 20% marks in each subject for appearing in the further rounds of selection

The difficulty level was more or less the same as that ofCDS 1 2025 CDS paper. CDS 1 2026 had more questions from current affairs related GK and a longer math paper. The English paper remained the same in format and level of difficulty, whereas Mathematics required the participants to manage time efficiently because of more multi-step computation based questions.

The above memory-based questions cover the general trend and topics covered in the exam and serve as an authentic reference for the candidates appearing in the CDS 2 2026.

Based on feedback shared by candidates after the examination, individuals' experiences may differ- Most candidates found it to be the highest-scoring section.

• English was easier than expected, mostly focused on grammar, vocabulary, and reading comprehension. Most candidates found it to be the highest-scoring section.
• General Knowledge was at a moderate level. StaticGK and Current Affairs had decent importance. Defence, polity, history, and science got considerable importance.
• Current Affairs was moderate in difficulty-focusing mostly on 8-12 months back. Candidates who are regular with newspapers and monthly current affairs magazines felt comfortable.
• Mathematics was the most time-consuming paper, especially due to Arithmetic, Algebra, and Mensuration questions that involved multiple calculation steps. Several Mathematics questions were lengthy, requiring careful calculations rather than difficult concepts. Formula revision proved more beneficial than advanced problem-solving techniques.
• Time management was challenging, especially in the Maths paper where several candidates were unable to complete all questions. Some candidates were unable to complete all the questions, because of limited time.
• The English paper boosted overall confidence, allowing candidates to finish early and review their answers before submission.
• General Knowledge was a mixture of conceptual as well as fact-based questions, making it tough for the candidates to bank upon solely the current affairs for it.
• Negative marking influenced the attempting strategy for almost everyone as candidates avoided making guess work and skipped unattempted questions.

Overall it was considered to be a moderate paper with no unusual changes in the pattern and an expected distribution of questions as per recent CDS 1 exams.

• IMA -125+ can give a good opportunity to clear written cut-off whereas 135+ can provide a comfortable margin.
• INA -115+ candidates can be in a competitive range whereas 120+ is a secure score.
• AFA - In AFA cutoffs are high therefore one should try for 145+ to get selection for SSB.

• The difficulty level in the paper makes the candidates believe that written cutoffs will be similar to last year. Since the paper was not of increased difficulty it was moderate, so only 2-5 marks variation can be expected in cut-offs for all the academies.
• It is assumed AFA would have the highest cutoff, while OTA would have the most competitive cutoff as well due to a huge number of aspirants.

• One who scored beyond the expected written cutoffs should start with the preparation for SSB and not wait for the result.
• Cracking the written test would be just the first phase, and it is also equally important to do well in the SSB interview to have an edge on the final merits.
