How to Start UPSC Preparation
A week-by-week, 90-day actionable plan from day zero to your first full-length test. No platitudes, no expensive purchases, just exact instructions.
Most pages that answer this question give you principles. Be consistent. Read the newspaper. Revise often. All of that is true and none of it tells you what to do on Tuesday.
This page tells you what to do on Tuesday. It covers your first ninety days, week by week, with a defined output at the end of each week. Ninety days is chosen deliberately: it is long enough to build a base in the two subjects that carry the most marks, and short enough that you can commit to it without deciding whether you are going to give the examination three years of your life. At the end of it you will have read enough and attempted enough to make that decision on evidence instead of on enthusiasm.
You do not need to buy anything before you begin. You do not need to join a course before you begin. Everything in the first six weeks is free and available online from official sources.
Before week one, understand what you are actually preparing for
The Civil Services Examination has three stages, and beginners routinely prepare for the wrong one:
- Preliminary examination: Two papers on a single day. General Studies Paper I carries 200 marks and decides whether you go through. The Civil Services Aptitude Test, Paper II, also carries 200 marks but is qualifying only — you need 33 per cent and the marks do not count towards your rank. Both papers are objective, and there is a penalty of one-third for wrong answers.
- Main examination: Nine written papers over roughly five days. Two are language papers that are qualifying only. The remaining seven — the Essay, four General Studies papers and two Optional papers — carry the marks that build your rank, at 250 each (1,750 total). (UPSC Civil Services Examination Rules.)
- Personality Test: An interview of roughly half an hour before a board, carrying 275 marks. (UPSC Civil Services Examination Rules.)
Two consequences follow, and they shape the whole ninety days:
Almost everything you read for Mains also helps you in Prelims. Almost nothing you memorise purely for Prelims helps you in Mains. So you read for Mains from day one and treat Prelims as the thing you convert to in the last four months. Beginners who invert this spend a year memorising facts and then discover in the Mains hall that they cannot write.
The official syllabus for the entire examination runs to a handful of pages. It is not a list of topics to be covered; it is a list of areas from which questions may be set. You cannot finish it. You can only build enough foundation to answer intelligently from it, and that distinction is the single most important thing a beginner can internalise.
For the full structure, see our guide to the UPSC exam pattern. Before you go further, check that you are actually eligible: eligibility criteria, age limit and number of attempts.
Weeks 1 to 2 — Read the examination before you read a book
Week 1 output: A printed syllabus, annotated
Time required: about eight hours across the week.
Download the current Civil Services Examination notification from upsc.gov.in and read it. All of it, including the parts about the application form. It is a dull document and it is the only authoritative description of what you are attempting. Everything else, including this page, is interpretation.
Then print the syllabus — Prelims and Mains — on paper. Not a PDF on your phone. Paper, in a folder you will keep for three years. Go through it with a pen and mark each line in one of three ways: I have studied this at school or college, I have heard of this, I do not know what this means. That map is your starting position and you will be surprised how much of it is in the first two categories.
Our plain-English breakdown of each paper is at the UPSC syllabus, explained.
Week 2 output: Three years of question papers read, none attempted
Time required: about ten hours.
Download the last three years of Prelims Paper I and the last three years of General Studies Mains papers from the UPSC website, or from our previous year question papers archive.
Do not attempt them. Read them. Read them with the annotated syllabus beside you and mark, for every question, which line of the syllabus it came from. This takes several hours and it will feel unproductive. It is the highest-return ten hours in the whole ninety days, because it teaches you the thing no book teaches: the depth at which UPSC actually asks. Candidates who skip this step read a 700-page reference book on Modern History and then find that the paper asked four questions, three of which were answerable from a school textbook.
By the end of week two you should be able to say, in your own words, what the examination is testing. If you cannot, read the papers again before you move on.
Weeks 3 to 8 — The NCERT base
Output: The core school textbooks read once, with notes.
Time required: roughly three hours a day on weekdays and five on weekends, or about twenty-five hours a week.
This is the phase everyone talks about and most people do badly. Two errors are common: reading every NCERT from Class VI to Class XII in every subject, which takes five months and is unnecessary; and reading them like a school student revising for an examination, which produces nothing usable.
| Week | Subject & Core Books | Approximate Load |
|---|---|---|
| Week 3 | Polity — school civics and political science, Classes IX to XII | Five books |
| Week 4 | Modern Indian History — Class XII, then medieval and ancient material | Three to four books |
| Week 5 | Geography — physical geography first, then Indian geography | Four books |
| Week 6 | Economics — Classes IX to XII | Four books |
| Week 7 | Environment, ecology and general science | Selected chapters only |
| Week 8 | Buffer week — finish what slipped, and revise weeks 3 to 7 | — |
Full detail on what to extract from each book, and what to skip, is on our NCERT books for UPSC page.
Week 8 is not optional and it is not padding. Every honest study plan has a catch-up week built in, because every real week contains a wedding, a viva, a fever or a power cut. A plan with no slack is a plan that fails in week three and takes your confidence with it.
On note-making: Make notes only where the book does not already summarise well. For Polity, your notes should be almost nothing — the textbook is already compressed. For Modern History, a timeline is worth building. The test of a good note is whether you could revise the chapter from it in six minutes. If it takes twenty, you have copied the book.
On the medium: Every NCERT is published in Hindi and English, and several are available in other languages through State boards. If you intend to write the examination in Tamil, read our page on writing the UPSC examination in Tamil before you decide which language to build your notes in. Switching medium in year two is expensive.
Weeks 9 to 12 — Current affairs, and your first written answers
You now have a base. From here the two habits that decide the examination begin:
Habit one: A newspaper, 30 to 45 minutes, six days a week
One national daily. The Hindu and The Indian Express are the two most commonly used and either is sufficient; reading both is a way of feeling busy. Read the editorial page, the national pages, the international page and the economy pages. Skip the city pages, sport, and almost all of the front page.
The mistake to avoid is note-making from day one. For your first month, read without taking notes at all. You do not yet know what matters and you will end up copying out news. From week eleven, start a single running document organised by the Mains General Studies syllabus headings — not by date — and add to it only when an article changes your understanding of a syllabus topic rather than merely reporting an event.
Habit two: Answer writing, from week nine, not from year two
This is the recommendation that separates a plan that works from a plan that reads well. Most beginners defer answer writing until they have "finished the syllabus", which means they defer it forever. Start in week nine, when you have read six weeks of NCERTs and can actually say something:
- Weeks 9 and 10: One 150-word answer a day, from a past General Studies question on a topic you have just read. Twelve minutes, handwritten, timed.
- Weeks 11 and 12: Two answers a day, one at 150 words and one at 250 words.
You will write badly. Everyone writes badly for the first two months. The point is to build the physical habit of producing structured prose under time pressure, which is a motor skill as much as an intellectual one. Our guide to UPSC answer writing shows two full annotated answers with the marks-earning parts identified.
Week 12 output: Your first full-length Prelims paper, under exam conditions
Sit one complete General Studies Paper I from a past year. Two hours, no breaks, no phone, no looking anything up. Mark it honestly, applying the negative marking.
Your score will be low. That is expected and it is not a verdict. What you are extracting is the diagnosis: how many questions you could not attempt because you had not read the area, how many you got wrong because you guessed, and how many you got wrong because you knew the topic and misread the question. Those are three different problems with three different fixes, and you cannot see them without sitting the paper.
What ninety days should have produced
By day ninety you should have:
- A printed, annotated syllabus and a working sense of the depth at which questions are asked.
- The core NCERTs read once, with short notes.
- Six weeks of daily newspaper reading and four weeks of syllabus-organised current-affairs notes.
- Around forty handwritten answers.
- One full-length Prelims paper attempted, marked and analysed.
- A decision, made on evidence, about whether you are going to continue.
That last one matters. Ninety days of honest work is enough to know whether this examination suits you. If it does not, you have lost three months and no money, and you have learned a great deal about India. That is not a failure and nobody should tell you it is.
Four things not to do in your first ninety days
You need the NCERTs, which are free to download from ncert.nic.in, and a newspaper. Everything on our UPSC booklist is for month four onwards.
You cannot judge a subject you have not encountered at examination depth. Choosing in month one on the basis of which subject "scores highest" is the most common expensive mistake in this examination. Read choosing an Optional subject at around month four.
Colour-coded folders, elaborate digital vaults and hand-drawn mind maps are displacement activity. Notes should be ugly and short.
Including here. Coaching bought in the first flush of motivation is coaching that goes unattended by month three. We have written, in our Director's own words, about when you should not take coaching, and it names the situations where the honest answer is no.
After day ninety
The ninety-day plan is the on-ramp. What follows is a twelve-month cycle built around the examination calendar: foundation reading and Optional selection in months four to six, the first full Mains-oriented pass in months seven to nine, and the conversion to Prelims in the final four months before the paper.
As per the UPSC Annual Calendar 2027, the CSE 2027 notification is due on 13 January 2027, applications close on 2 February 2027, the Preliminary examination is on 23 May 2027 and the Main examination commences on 20 August 2027. UPSC states that these dates are liable to alteration; check upsc.gov.in calendar before you plan around them.

If your circumstances are not "full-time from tomorrow"
Most people who start this examination are doing something else at the same time. Two pages here are written for those situations specifically, with real timetables rather than encouragement:
- Still in college: UPSC preparation for college students, year by year, including what to tell your parents.
- Working full time: UPSC preparation while working, with an hour-by-hour weekly schedule built around a 45-hour job, and an honest answer on whether to resign.
Frequently Asked Questions
How long does it take to prepare for UPSC from zero?
For a candidate starting with no prior preparation and studying full time, twelve to fifteen months of sustained work is a realistic first cycle. Working professionals and college students should plan on eighteen to twenty-four months to reach the same level of readiness. Anyone offering a shorter number is describing an exception rather than a plan.
Can I start UPSC preparation without coaching?
Yes. Nothing in the first ninety days described on this page requires a course, and the material is free from upsc.gov.in and ncert.nic.in. Whether you should take coaching later depends on your circumstances rather than on the examination, and we have set out the cases where the answer is no on our page about whether you need coaching.
Which newspaper should I read for UPSC?
One, daily, for thirty to forty-five minutes. The Hindu and The Indian Express are the two most widely used by candidates and either is adequate. Reading two newspapers is almost always a substitute for reading one properly.
Should I start with NCERT books or with standard reference books?
NCERTs first, without exception. Reference books assume a base that NCERTs build. Reading a 700-page standard text before the school textbooks produces the sensation of studying without the retention. Our NCERT books for UPSC page gives the reading order.
When should I start answer writing?
Week nine of this plan, not year two. Answer writing is a skill built by repetition under time pressure, and it improves slowly. Beginning it once the syllabus is 'finished' is the most common reason candidates clear Prelims and then fail Mains twice.
Do I need to decide my Optional subject before I start?
No, and you should not. Around month four, once you have encountered several subjects at examination depth, is early enough. See choosing an Optional subject.
I am in Coimbatore and starting now. Is there anyone I can talk to?
Yes. Samkalp IAS Academy - Coimbatore offers a free counselling session with no obligation to enrol. It is a conversation about where you are and what the examination realistically demands, and if we think you should wait a year or prepare on your own, we will say so.
