Can you clear Prelims without coaching? Yes. A coaching class gives you a plan: what to study, in what order, how deeply, and tests to check your learning. You can get all of this yourself. This guide shows you how.
1Understand the Exam First
Prelims has two papers on the same day. Each paper is of 200 marks (UPSC's notice).
Paper I (General Studies) has 100 questions. Only this paper decides if you pass the cut-off.
Paper II (CSAT) is a qualifying paper. You need 33% marks in it.
For every wrong answer, you lose one third of the marks of that question.
Read the official syllabus once. Then solve the Prelims papers of the last ten years. Do this before you start any book. These papers show you what UPSC really asks, and which parts of the syllabus it rarely asks about.
In Agyan Shatru: All of UPSC's Prelims questions from 1995 to 2026 are sorted by topic. Every concept has an importance rating based on 30+ years of these questions.
2Start with NCERTs
NCERT textbooks are easy to read and free. UPSC questions are built on them. AIR 1 Anudeep Durishetty begins his Prelims book list with the NCERTs. Read them to understand the ideas. You do not need to learn them by heart yet. Keep your notes short.
In Agyan Shatru: Every topic shows its concepts in the order you should read them, with free resources for each. You can start reading at once.
3Then Read One Standard Book for Each Subject
Choose one book for each subject and read it many times. This works better than reading many books one time each. This is the main part of Anudeep Durishetty's book list:
Polity
Indian Polity, M. Laxmikanth
Modern History
A Brief History of Modern India (Spectrum)
Ancient and Medieval History
Old NCERTs: R.S. Sharma, Satish Chandra
Art and Culture
An Introduction to Indian Art (NCERT Class XI), CCRT material
Geography
NCERT Classes XI and XII, and G.C. Leong
Economy
Indian Economy, Ramesh Singh, with the NCERTs and the Economic Survey
Environment
Shankar IAS Environment
Science
NCERT Classes IX and X, and science in the news
In Agyan Shatru: Each concept has a “What to Study” note. It tells you how deeply to study that concept, so you spend your time on the parts that Prelims asks about.
4Make a Timetable You Can Follow
Start from the exam date and plan back to today. Some simple rules:
Study two subjects in the same week: one difficult subject and one easier subject.
Keep one day every week free. Use it to finish the work you could not complete.
Plan for some bad days. If your timetable has no free time, one missed day can spoil the whole week.
Anudeep Durishetty says that for a beginner, one year is more than enough to cover the complete syllabus.
In Agyan Shatru: Follow the ready Course Plan, or make your own plan from a template. You can plan the whole course or only some subjects, for 2 weeks up to a year, with 1 or 2 subjects a day. Work you miss moves to your backlog days on its own.
Let Agyan Shatru Make Your Plan. Your First Day Is Ready.
Agyan Shatru turns these steps into a plan for every day, down to every concept. You get tests after every topic.
Before you read: look at the syllabus for the topic and its past questions. Then you know what to look for.
While you read: use your one book. Write short notes in your own words.
After you read: close the book and test yourself. If you cannot remember it, read it again.
In Agyan Shatru: Every topic is made in these three steps: Pre-Study, Study and Post-Study. The flashcards and MCQs are ready at the end, and a study timer runs while you read.
6Read the News Every Day
Read one newspaper: The Hindu or The Indian Express. Look for news that is linked to the syllabus. You can skip political news. Anudeep Durishetty reads the paper for 30 to 45 minutes, and he finishes all his current affairs work in about two hours a day. He also reads one monthly compilation.
Connect each news item to a topic in the syllabus. For example, news about a new Ramsar site goes with the topic of wetlands. News about a court judgement goes with the Article of the Constitution it is about. Revise the news together with its topic.
In Agyan Shatru: Every topic lists the best resources for it, including links shared by other students. So new material stays next to the topic it belongs to.
7Revise Many Times
Anudeep Durishetty writes, “Revision is the absolute key.” Revise each topic three times: within one week of reading it, again within one month, and again before the exam. Revise from your short notes and flashcards. In the last few weeks, do not start any new topic.
In Agyan Shatru: Every topic has active recall flashcards. My Notebook keeps your mistakes and saved questions in one place, so you can revise them.
8Take Tests and Learn from Your Mistakes
Take a short test after every topic. In the last few months, take full-length tests in exam conditions. After each test, spend time on your mistakes. For each wrong answer, ask: did I not understand the concept, did I forget a fact, or was I careless?
In the exam, Anudeep Durishetty answers in two rounds. In the first round, he answers the questions he is sure about and marks the doubtful ones. In the second round, he comes back to the doubtful ones. Do not spend too long on one question.
In Agyan Shatru: Topic-wise tests, topic-wise PYQs and full-length tests. Every MCQ has an explanation, and every wrong answer is saved so you can study it again.
9Prepare for CSAT Early
CSAT is only a qualifying paper, so many students ignore it. Some of them fail Prelims because of it. Solve one CSAT paper early to see your level. If you are not sure of getting 33%, practise maths and reasoning every week. Anudeep Durishetty says CSAT needs the same seriousness as Paper I.
In Agyan Shatru: Give CSAT its own sessions on the study timer, with a daily target. My Notebook's calendar shows every hour you study.
Mistakes Self-Studiers Make
Too Many Books
Reading one book three times works better than reading three books one time each.
Reading Without Tests
You may feel you know a page. But in the exam, you must remember it without the book.
No Revision Plan
If you do not revise a topic within a month, you forget most of it.
No Free Days
If your timetable has no free day, one missed day can spoil the whole week.
Ignoring CSAT
If you get less than 33% in CSAT, you fail Prelims, even with a good score in Paper I.
What Toppers Say About Self‑Study
These are the toppers' own words, in order of rank. Even toppers who took coaching say that self-study helped them a lot.
AIR1
“It's all about his own hard work and dedication.”

AIR9
“Since I did not join any coaching, I referred to online material quite generously.”
“This information overload has been able to level the playing field between those aspirants who are heavily reliant on coaching and others like me who have never taken any formal coaching.”
Yes. Prelims checks what you know. It does not matter where you learnt it. If you have a plan for every day, one good book for each subject, regular revision and tests, self-study at home is enough.
Do UPSC Toppers Recommend Self-Study?
Yes. Anuj Agnihotri, AIR 1 in CSE 2025, prepared without a coaching centre, his father says. Saumya Sharma (AIR 9, CSE 2017) and Tanu Priya (AIR 18, CSE 2012) cleared in their first attempt without coaching, and even Satyam Gandhi (AIR 10, CSE 2020), who took coaching, says the candidate needs to focus more on self-study.
How Long Does UPSC Prelims Self-Study Take?
AIR 1 Anudeep Durishetty writes that for a beginner, one year is more than enough to cover the complete syllabus. Agyan Shatru's plans run from 2 weeks to a year, with 1 or 2 subjects a day.
Which Books Do I Need for UPSC Prelims Self-Study?
Start with NCERTs, then one standard book per subject: Laxmikanth for Polity, Spectrum for Modern History, G.C. Leong with the NCERTs for Geography, Ramesh Singh for Economy and Shankar IAS for Environment.
