Start with three things: the exam notification, a recent question paper and one textbook for the topic you are studying. You can obtain these from UPSC and NCERT without buying a bundle of notes. This guide links to the publishers and gives you a practical way to use the material.
The reading order below is our suggested starting plan, not a prescribed UPSC booklist or a promise that these resources alone cover every question. Choose chapters against the syllabus and your own gaps.
Download these first
1. UPSC syllabus and exam notification
Open UPSC's active examinations, select Civil Services (Preliminary) Examination for the relevant year, then choose Download Notification → Notice. Use the notification's scheme and syllabus sections alongside any later corrigenda.
For reference, the 2026 CSE examination page includes its notification. Check the notification for your target year when available; an older one is a study reference, not confirmation of future rules.
2. Previous papers and answer keys
Use UPSC's previous question papers to select the exam, year and paper. Save both Prelims GS I and GS II (CSAT); for Mains, select the papers relevant to your preparation. Check UPSC's separate answer-key page for released objective-paper keys. Match the year and booklet series before scoring.
Keep official question papers separate from coaching explanations and Improvam's original practice questions. An explanation from a third party is not an official answer key.
3. NCERT textbook PDFs
On the NCERT textbook portal, choose the class, subject and book. Open the contents and download the chapters you need. Check the title, language and edition shown in the file; chapter numbering can differ between editions.
Start with school-level material if a topic is unfamiliar. If you already understand the basics, test yourself first and read the chapters behind your mistakes instead of restarting every book.
A subject-wise reading map
Use this as a way to organise your first pass. All textbook suggestions refer to the NCERT portal; choose from the editions currently listed there.
- Polity: begin with civics and political science topics about the Constitution, institutions and rights. After reading, write down who has a power, who checks it and any exceptions you need to verify.
- Geography: work through physical and Indian geography topics with an atlas beside you. Draw a simple map or process diagram from memory before reopening the chapter.
- History: build a chronology, then add causes and consequences. Keep separate notes for art and culture so names and terms do not disappear inside a long timeline.
- Economy: learn basic concepts before collecting current statistics. Explain a term in your own words and connect it to a recent example.
- Science and environment: use science chapters to repair specific gaps, then connect the concept to an application or environmental issue. Treat this as a foundation, not a complete specialist reading list.
- CSAT: begin with a timed diagnostic using an official paper. Choose comprehension or numeracy practice based on the errors you actually make; do not leave this diagnostic until the final weeks.
Our UPSC preparation hub and CSAT page provide routes into further practice. For a short browser-based starting point, try eight free foundation questions. They are original practice, not a current-news test or an official UPSC paper.

Add current affairs with a purpose
Bookmark a small number of sources and use them to answer a specific question in your notes:
- Economic Survey: the official portal provides chapters and a statistical appendix. Choose the chapter relevant to your topic, and record the year, unit and source beside any figure you use.
- Press Information Bureau: use government releases to check what a ministry announced. Read the publication date and any linked document; an announcement alone does not establish how a programme performed.
- RBI annual reports: use the report for the relevant financial year when researching banking and monetary developments.
- PRS Legislative Research: use bill summaries and policy reviews to orient your reading. PRS is an independent research organisation, not a government department; follow through to the underlying document when you need the exact provision.
For each selected issue, write four short notes: what changed, which syllabus topic it connects to, the source and date, and one question you should be able to answer. Avoid copying entire releases into a notebook you will not revisit.
Your first seven days
This is a suggested setup week, not a seven-day preparation course. Reduce the reading load if you have less time, while keeping the review step.
- Day 1 — organise: save the notification and syllabus. Create folders for official papers, textbooks and your own error log.
- Day 2 — diagnose: attempt a manageable set of questions without notes. Mark whether each error came from missing knowledge, misreading or uncertainty.
- Day 3 — repair: read one chapter tied to those errors. Close the PDF and explain the main ideas aloud or on paper.
- Day 4 — retrieve: revisit the topic without looking at yesterday's notes, then try a different set of questions.
- Day 5 — connect: select one current-affairs issue related to the topic and make the four-note summary described above.
- Day 6 — check CSAT: attempt a timed section and identify the next skill to practise.
- Day 7 — review: retry missed questions, explain why the other options are wrong, and choose next week's topic from the remaining gaps.
Copy these headings into a notebook for each session: Topic · Source/edition · Questions attempted · Mistake · Correct explanation · Next review date. The useful output is a smaller list of unresolved mistakes, not a larger downloads folder.
Before trusting a PDF
Check the publisher, exam year, paper name, language and edition. For answer keys, check the booklet series too. Keep the original filename or add that information when renaming the file. If a link breaks, return to the publisher's listing page instead of assuming a similarly named file elsewhere is the same document.
Prefer the original publisher where possible. A watermark alone does not prove a file is inaccurate or pirated, and an official document still needs the correct date and context.
Common questions
Is this a single downloadable UPSC study-material PDF?
No. It is a guide to separate publisher-hosted resources. Select the syllabus, papers and chapters you need; Improvam does not package these documents into a combined PDF.
Are NCERTs enough for the whole exam?
Use them as a foundation. Compare your coverage with the syllabus, review actual papers, and add targeted reading and practice where gaps remain. Your optional subject and answer-writing preparation need their own plan.
Can I use these resources in Hindi?
Check the language choices on the relevant publisher's page and inside each downloaded document. Do not assume that every item has a matching translation or the same pagination.
How should I choose additional paid material?
Identify the gap first: feedback on writing, explanations for a difficult subject, or timed practice. Review sample material against that need before paying. A second copy of notes you already have may not help.
When was this guide reviewed?
The source listing pages and study guidance were reviewed on 10 September 2026. We replaced the old syllabus link and added the reading map and setup checklist. Individual documents may be revised later; verify the edition and any newer notices on the publisher's website.
