Walk into any bookstore or browse any e-commerce platform today and you will find dozens of CDS solved paper books from various publishers. Most of them are well-structured, widely used, and reasonably updated. There is, however, one thing nearly every available option has in common — they all stop at 2025.
Physics Wallah's newly released CDS Chapter-wise & Topic-wise 23 Previous Years Solved Papers (Book Code: IMS0172) is the only book currently available in India that includes the CDS 1 2026 paper, conducted on April 12, 2026. For any aspirant targeting CDS 2 on September 13, 2026, that single fact changes the entire preparation calculus.
This is not just a marketing point. It is a preparation advantage with real exam consequences.
The CDS exam has increasingly focused on current affairs, with a noticeable emphasis on national and international events, defence-related updates, and governmental policies. In the English section, there has been a shift toward more comprehension-based questions requiring deeper understanding of context and vocabulary.
UPSC's question-setting evolves every cycle. A candidate who has studied only up to the 2025 paper is essentially working with an 18-month-old picture of the exam. The April 2026 paper — sitting inside IMS0172 and nowhere else in print — reveals the latest shift in difficulty level, topic emphasis, and question construction style. That is the difference between being prepared and being fully prepared.
IMS0172 spans 23 full papers — both CDS I and CDS II — from 2015 through 2026. That is the deepest historical bank available in a single volume right now, covering the entire era of the current exam pattern, and it includes the most recent paper.
Questions are not arranged year-by-year, which makes pattern spotting tedious. Instead, every question is reorganised chapter-wise and topic-wise. A candidate studying Trigonometry or Indian Polity can instantly see every question that has appeared on that topic across all 23 papers in one place. In CDS papers, English, General Knowledge, and Science have historically commanded the highest number of questions, while Polity, Current Affairs, and Geometry/Trigonometry are consistently very important. The book's structure is built specifically around that reality.
General Knowledge, English, and Elementary Mathematics are all covered in full in a single volume — suitable for IMA, INA, and AFA candidates who must sit all three papers, and equally useful for OTA candidates focused on English and GK alone.
A dedicated trend analysis maps the last five years of question distribution, showing which topics are rising in frequency, which are declining, and where revision effort is best concentrated before CDS 2 2026.
Each answer comes with a solution designed to explain why, not just what. The CDS Maths paper is based on Class 10 level — the concepts are not advanced, but speed and accuracy under exam conditions determine the score. The explanations in IMS0172 directly target that speed-accuracy gap.
Practising UPSC CDS previous year question papers is the smartest way to prepare for the examination, helping candidates understand the exam pattern and improving overall preparation level.
Since there is negative marking in the CDS exam, it is important to attempt questions wisely. Practising question papers helps candidates understand which questions to attempt and which to skip, thereby minimising unnecessary loss of marks.
Solving the previous year's question paper is a great way to evaluate a candidate's performance, helping identify strengths and weaknesses.
The chapter-wise structure of IMS0172 adds one more layer to this — you learn not just what was asked but how questions in each chapter are typically framed, making skip-or-attempt decisions faster and more accurate on exam day.
General Knowledge
According to recent CDS exam trends, most questions from the General Studies section come from current affairs, general science, geography, history, and polity. With 23 papers to draw from, the GK chapter bank in IMS0172 is the most comprehensive single-source reference currently in print.
Elementary Mathematics
In Mathematics, questions are mainly asked from geometry, trigonometry, number system, algebra, and mensuration. All of these are organised chapter-wise, allowing candidates to concentrate preparation on the highest-yield areas first.
English
In English, most questions come from reading comprehension, vocabulary, error spotting, sentence improvement, and cloze test. The 2026 paper, now inside this book, reflects the latest evolution of this section's difficulty and structure.
CDS 2 2026 has been scheduled for September 13, 2026. That leaves under three months from today. Candidates are advised to solve at least the last 5 to 10 years of CDS question papers for better preparation. IMS0172 covers more than double that range, and does so within the current exam pattern era — meaning every question in it is directly relevant to what a candidate will face in September.
This is the right resource if you are:
Appearing for CDS 2 2026 on September 13 and need the most current question bank available in print
A repeat CDS aspirant who wants to identify exactly which chapter-level gaps cost marks in previous attempts
A first-time aspirant who wants a single structured volume covering over a decade of authentic UPSC questions
Someone who has been relying on free PYQ PDFs and wants properly explained solutions in an organised, exam-oriented format
An OTA candidate who needs English and GK questions arranged by topic for targeted revision
