CDS 2 2026 Exam Pattern: Paper-Wise Marks and Duration

The CDS 2 2026 exam pattern differs based on the academy you are targeting. Getting this distinction right before building your study schedule matters more than most candidates realise.

For IMA, INA, and AFA: three papers are conducted, the CDS English paper, the CDS General Knowledge paper, and CDS Elementary Mathematics. Each paper carries 100 marks, and CDS paper duration is two hours per paper, giving a total of 300 CDS written test marks.

For OTA: only two papers are conducted, English and General Knowledge, each carrying 100 marks for a total of 200 marks. Mathematics is not tested for OTA candidates.

• IMA/INA/AFA: English (100) + GK (100) + Maths (100) = 300 marks total

• OTA: English (100) + GK (100) = 200 marks total

• Each paper: 2 hours duration, objective type, multiple choice

CDS 2026 Marking Scheme: How Negative Marking Works

The CDS marking scheme negative marking rule is straightforward but frequently misread. Each correct answer awards plus one mark. Each wrong answer deducts 0.33 marks, one-third of a mark per incorrect response. Unattempted questions carry zero penalty.

Blind guessing will cost you marks. At the same time, skipping every uncertain question is also a losing approach, since the cutoff demands volume. The practical rule: attempt a question only when you can confidently eliminate at least one of the four options.

Eliminating even one option shifts your odds from 25 percent to 33 percent per attempt, which is statistically worthwhile given the plus-one reward against the minus-0.33 penalty. Apply this consistently across all three papers, not selectively.

Subject-Wise Syllabus and Topic Weightage for CDS 2 2026

The CDS 2 2026 syllabus covers three broad subjects. CDS subject wise weightage within each paper is not officially published, but historical papers reveal consistent high-frequency clusters worth building your schedule around.

English: Spotting errors, sentence improvement, and fill-in-the-blanks make up the grammar-heavy portion. Reading comprehension passages carry significant weight. Idiom-heavy questions on rare phrases appear infrequently and are worth skipping in the final stretch.

General Knowledge: Current affairs, modern history, geography (physical and Indian), and general science form the core. Polity and economics appear consistently across papers. Ancient history and fine arts are low-frequency and suitable to deprioritise.

Elementary Mathematics: Arithmetic covering number systems, percentages, ratio, and profit and loss, along with algebra, carries the highest marks. Geometry and mensuration follow closely. Probability and set theory appear infrequently and can be set aside under time pressure.

Knowing the current affairs cutoff for CDS is also important. Cover events up to one month before the exam date to stay within the relevant window.

Last-Minute Revision Plan for CDS 2 2026: 30, 15 and 7-Day Triage

Knowing how to prepare for CDS in 30 days requires a tiered approach, not uniform coverage across everything. The CDS last minute revision plan below is built around urgency tiers.

30-Day Phase: Balanced coverage across all three subjects. Dedicate five days per subject per cycle. Start the CDS mock test strategy from week two, running one full mock every three days to track baseline accuracy.

15-Day Phase: Shift entirely to high frequency topics CDS. Drop low-weightage chapters. Run one mock test every two days and review wrong answers the same evening, not the next morning. Focus on GK current affairs and Maths arithmetic during this window.

7-Day Phase: Revision only, no new topics. Run one full mock daily. Maintain an error log revision technique, writing every repeated mistake into a single notebook and reviewing it each morning. This habit alone can add five to eight marks in the final week.

High-Score Tips: What to Prioritise in the Final Stretch

The SSB interview after CDS comes only after clearing the written test, so the written stage deserves complete focus right now. These six tactics separate consistent scorers from average performers.

• Analyse mock test errors before attempting the next mock. Repetition without correction builds bad habits.

• Cover current affairs from June 2025 through one month before exam day to stay within the current affairs cutoff for CDS.

• For English grammar quick-wins, drill subject-verb agreement, tense consistency, and preposition errors. These question types appear in every paper.

• In Maths, prioritise arithmetic and algebra over geometry. They account for the majority of solvable questions within the two-hour limit.

• Use the error log revision technique daily. A mistake noted but not revisited is a mark lost twice.

• Avoid picking up new reference books in the final two weeks. Depth on known material consistently beats breadth on unfamiliar content.
