CDS-2 2026: Last 5 Years' Papers Analysis — GK, Maths & English Trends

CDS-2 2026: Last 5 Years' Papers Analysis — GK, Maths & English Trends

Every serious CDS aspirant eventually discovers the same truth: the Combined Defence Services exam is remarkably predictable. Conducted twice a year by the UPSC, its three papers - English, General Knowledge and Elementary Mathematics - draw from the same pool of topics year after year, with only the questions rephrased.

This analysis looks at the last five years of CDS papers and pulls out the patterns that matter: which maths topics carry the most weight, how GK splits across subjects, and what English keeps testing. Read it as a map of where your preparation hours will pay off most.

A note on the numbers below: these are approximate distributions observed across recent CDS papers, not official figures. UPSC never publishes a topic-wise breakdown, and the exact count shifts a little each session. Treat the ranges as a guide to relative weight, not a guarantee.

Why Previous Year Papers Matter in CDS

Unlike exams that reinvent themselves each year, CDS rewards familiarity. The maths paper recycles roughly the same fifteen topics. English tests a fixed set of grammar rules. GK leans heavily on the static portions - history, geography, polity and science - that never really change.

That means a candidate who has worked through five years of past papers walks into the hall having already seen the shape of almost every question. The concepts repeat; only the wrapping is new. You can browse every recent CDS paper, organized by year and subject, on Padhify to see this for yourself.

The maths paper (100 questions for IMA, INA and AFA) is where PYQ analysis pays off most, because the topic weightage is the most stable of the three papers. Arithmetic dominates, and geometry plus mensuration together form the second pillar.

Topic Area Approx. Questions (out of 100) Trend
Arithmetic (percentages, profit and loss, time and work, time-speed-distance, ratio) 30 to 35 Consistently the largest block
Geometry 16 to 20 Stable, high-yield
Mensuration (2D and 3D) 12 to 15 Stable
Trigonometry 12 to 15 Stable, formula-driven
Algebra 10 to 12 Slightly variable
Statistics and Data 5 to 8 Small but easy marks

The takeaway is clear: arithmetic and geometry alone account for roughly half the paper. A candidate weak in these two areas cannot compensate elsewhere. Trigonometry and mensuration are pure formula-and-practice topics - high return for the time invested.

Put the trend to work: solve CDS Elementary Mathematics previous year questions topic-wise on Padhify - start with arithmetic and geometry, then move to trigonometry and mensuration.

The GK paper (120 questions) is the widest in scope but still follows a recognizable split. General Science and the static humanities (history, geography, polity) carry the bulk; current affairs is significant but rewards steady monthly reading rather than last-minute cramming.

Subject Approx. Questions (out of 120) Trend
General Science (Physics, Chemistry, Biology) 28 to 32 Largest single block
History (Ancient, Medieval, Modern) 18 to 22 Static, heavily repeated
Geography (Indian and Physical) 18 to 22 Static, map-based
Polity and Constitution 15 to 18 Static, high-yield
Current Affairs 15 to 20 Rewards monthly revision
Economics 8 to 12 Concept-light, fact-heavy
Defence and Miscellaneous 5 to 8 Small, awareness-based

The pattern across five years is that the static portions - science, history, geography, polity - decide the GK score. These are the areas where past papers repeat almost verbatim, so a PYQ-first approach here is especially effective. Practice CDS General Knowledge PYQs on Padhify to lock down the static portions before you touch current affairs.

The English paper (120 questions) is the most learnable of the three, because it tests a closed set of question types. Once you know the format, the paper becomes a scoring opportunity rather than a hurdle.

Question Type Approx. Questions (out of 120) Trend
Ordering of Words and Sentences 20 to 28 Consistently large
Reading Comprehension 20 to 30 Stable
Spotting Errors 18 to 22 Grammar-rule driven
Synonyms and Antonyms 18 to 22 Vocabulary-based
Sentence Improvement 8 to 12 Stable
Idioms, Phrases and Fill-ups 10 to 15 Predictable

Notice that grammar and sentence-arrangement types together make up more than half the paper. These reward pattern recognition, not deep study - exactly the kind of skill built by solving past papers back to back. The fastest way to build that instinct is to work through CDS English previous year questions on Padhify.

What the Last Five Years Tell Us

Pulling the three papers together, a few conclusions hold up across every recent session:

  1. The blueprint barely moves. Topic weightage in all three papers has stayed within narrow bands. What worked two years ago works now.
  2. Static beats current. In both maths and GK, the repeatable, static topics carry more marks than the fast-changing ones. Build there first.
  3. English is the accelerator. It is the easiest paper to improve quickly, and a strong English score cushions a tough maths day.
  4. Accuracy compounds. With one-third negative marking on every paper, the trend among high scorers is disciplined attempts, not maximum attempts.

Knowing the trends is only half the work - the other half is training on the actual questions that produced them. The most reliable CDS strategy is to let previous year papers drive your plan:

  • Start with a full past paper, untimed, to see where you stand against the weightage above.
  • Attack the heavy blocks first - arithmetic and geometry in maths, static science and humanities in GK, grammar types in English.
  • Practice chapter-wise, not randomly. Master percentages, then time-and-distance, then trigonometry - one topic to fluency before the next.
  • Respect negative marking. Skip any question where you cannot eliminate at least two options.
  • In the final month, simulate the real thing - take a full CDS mock test, timed, with no breaks.

You can practice all CDS previous year questions chapter-wise on Padhify - GK, Elementary Mathematics and English papers from recent years, organised by topic, with a clear explanation for every answer. Working through them is the fastest way to turn the trends above into marks.

Frequently Asked Questions

Which maths topics carry the most weight in CDS?
Arithmetic is the largest block (around a third of the paper), followed by geometry and mensuration. Together, arithmetic and geometry account for roughly half the maths paper. You can practice them topic-wise here.
How much of CDS GK is current affairs?
Typically 15 to 20 questions out of 120. The larger share goes to static subjects - general science, history, geography and polity - which is why past GK papers are so useful here.
Is CDS English easy to score in?
It is the most learnable paper. More than half of it is grammar, error-spotting and sentence-arrangement - question types that repeat every year and reward practice over study.
Do CDS questions actually repeat?
The exact questions rarely repeat word for word, but the concepts and question types repeat relentlessly. A candidate who has solved five years of papers has seen the pattern of nearly every question.
How many past papers should I solve?
Aim for at least the last five years across all three papers, solved topic-wise first and then as full timed mocks in the final month.
