CDS Bundle 2026: Mock Tests, Previous Papers and Notes in One Plan
Mock tests, previous papers and notes for the CDS written exam, grouped so you can follow one plan for your chosen academy.
A CDS bundle groups the preparation material for the UPSC Combined Defence Services exam into one package, so you do not have to assemble mocks, notes and practice papers separately. It suits aspirants who want one plan for the written exam that covers English, General Knowledge and, for IMA, INA and AFA, Elementary Mathematics.
With the CDS II 2026 written result awaited and the CDS I 2027 exam tentatively listed for 11 April 2027 in the UPSC calendar, this is a practical time to plan. This page explains what a CDS bundle should contain, who it suits and how to use one across a cycle.
What a CDS bundle should include
Component | Purpose |
|---|---|
Full-length mock tests | Practise two-hour papers with one-third negative marking, as in the real exam |
Sectional and topic tests | Fix weak areas such as error spotting, polity or trigonometry before attempting full papers |
Previous year papers | Understand how UPSC frames questions and how difficult each paper really is |
Study notes | Revise static GK, grammar rules and maths formulas quickly |
Current affairs material | Cover recent events, defence exercises, appointments and awards for the GK paper |
Check the paper split before you choose. Candidates for IMA, INA and AFA write three papers of 100 marks each, while OTA candidates write only English and General Knowledge. If you list OTA along with any other academy, you take all three papers. The official scheme is in the notification on the UPSC website.
Who should choose a CDS bundle
First-time aspirants: A bundle gives you a complete set of tests and notes in one place, which saves time spent searching for material.
Repeaters aiming at the next cycle: If your weak area is one paper, a bundle lets you combine targeted topic tests with full mocks.
OTA aspirants: Pick a bundle that covers English and General Knowledge in depth, since there is no Maths paper to balance a weak score.
Working graduates and final-year students: Short sectional tests fit around a fixed schedule better than long classes.
How to use a CDS bundle
Weeks 1 to 6: Study with the notes and take topic tests after each chapter. Start a monthly current affairs file from the first week.
Weeks 7 to 10: Move to sectional tests and solve two or three previous year papers to judge the real level.
Final six to eight weeks: Take full-length papers under the two-hour limit, analyse each one the same day and revise from an error log.
The written exam is only half the merit. The SSB interview carries the same marks as the written test (300 for IMA, INA and AFA; 200 for OTA), so keep a little time each week for reading, speaking practice and fitness.
