• 1Print the syllabus from UPSC's Examination Notice and keep it visible; every topic you study should map to a line in it.
• 2Download five years of Preliminary General Studies Paper I and CSAT papers from UPSC's Previous Year Question Papers page and attempt one paper cold to get a real baseline out of 200.
• 3Read the negative marking rule until it is instinct: one-third of the marks for a wrong answer, the same penalty for marking two options, no penalty for a blank.
• 4Decide your optional subject now, because the choice is locked when the exam-specific form is submitted and it carries 500 of the 1,750 written marks.
• 5Set up a daily newspaper routine with The Hindu or the Indian Express, reading for governance, economy and international relations rather than for headlines.

• 1Work through NCERT Class 11 Indian Constitution at Work, available free from ncert.nic.in, before touching any standard reference.
• 2Read M Laxmikanth's Indian Polity chapters on the Preamble, fundamental rights, directive principles and the Union executive.
• 3Attempt every polity question from the last five UPSC Prelims papers and note which articles recur.
• 4Start a one-page-per-topic note format so revision later takes minutes, not hours.
• 5Track constitutional amendments and Supreme Court judgments reported in the newspaper against the chapters you have covered.

• 1Cover NCERT Class 12 Themes in Indian History Part III alongside Bipan Chandra's India's Struggle for Independence or the Spectrum modern history compilation.
• 2Build a single chronological timeline from 1757 to 1947 with the session, act or movement on one axis and the response on the other.
• 3Attempt UPSC's past Prelims history questions and sort them into events, personalities and acts.
• 4Read the Ministry of Culture and PIB releases on anniversaries, since UPSC draws culture questions from what the government has commemorated.
• 5Write one 150-word Mains-style answer daily on a history theme and cut it to the word limit.

• 1Work through NCERT Classes 6 to 10 geography and Class 11 Fundamentals of Physical Geography, then GC Leong's Certificate Physical and Human Geography for the physical topics.
• 2Practise map work daily: rivers, mountain ranges, national parks, straits and choke points, since UPSC asks location-based questions in Prelims.
• 3Read the current India State of Forest Report summary and the annual environment chapter of the Economic Survey at indiabudget.gov.in.
• 4Cover biodiversity conventions and Indian environmental legislation together, because General Studies III tests them as one block.
• 5Attempt a 60-question timed set mixing geography and environment to test speed under negative marking.

• 1Read NCERT Class 11 Indian Economic Development and Class 12 Macroeconomics before any coaching material.
• 2Work through the current Economic Survey and Union Budget documents on indiabudget.gov.in, both published by the Ministry of Finance.
• 3Learn the Reserve Bank of India's monetary policy instruments from rbi.org.in rather than from summaries.
• 4Map every scheme you meet to the ministry that runs it, the year it started and the problem it addresses.
• 5Attempt past Prelims economy questions and identify how many need calculation rather than recall.

• 1Read PIB releases daily for science and technology announcements, which is where UPSC sources most of its applied science questions.
• 2Cover basic biology, chemistry and physics from NCERT Classes 9 and 10 only to the level needed for application questions.
• 3Read the Yojana and Kurukshetra issues from the last six months, both published by the Publications Division.
• 4Consolidate six months of current affairs into a single thematic file organised by the General Studies paper each item feeds.
• 5Attempt a full 200-mark Prelims General Studies Paper I in two hours and calculate your net score after negative marking.

• 1Attempt three past CSAT papers under timed conditions; the pass mark is 33 per cent, but a weak comprehension section can end a cycle on its own.
• 2Drill reading comprehension first, since it carries the largest share of the paper and rewards technique over speed.
• 3Practise basic numeracy, data interpretation and logical reasoning at Class 10 standard, which is the level UPSC specifies.
• 4Work out your personal attempt threshold: with a one-third penalty, a random four-option guess has negative expected value unless you can eliminate at least one option.
• 5Schedule two CSAT sessions a week for the rest of the plan rather than dropping the paper.

• 1Read the optional syllabus line by line and collect UPSC's past optional papers for your subject from the Previous Year Question Papers page.
• 2Cover Paper 1 of the optional in outline, building a source list of two or three standard texts rather than ten.
• 3Write four full-length optional answers this week and mark them against the printed marks and word limits on UPSC's papers.
• 4Identify overlaps between your optional and the General Studies papers and study those sections once for both.
• 5Confirm the medium in which you will write the optional, since it is fixed at application time.

• 1Cover Paper 2 of the optional in outline and complete a second set of four written answers.
• 2Begin General Studies IV using the Second Administrative Reforms Commission reports, particularly the ones on ethics in governance and citizen-centric administration.
• 3Practise case studies by writing the stakeholders, the options, the option you would choose and the reason, in that order every time.
• 4Build a personal bank of about fifteen examples from administration, law and public life that you can deploy in ethics answers.
• 5Attempt the twelve-question structure of UPSC's 2025 General Studies IV paper in three hours.

• 1Write two full essays in three hours to the format of UPSC's published Essay papers, one abstract and one policy topic.
• 2Get each essay read by someone who will mark structure and expression rather than only content.
• 3Practise the nine-minute-per-question rhythm for General Studies: twenty questions in 180 minutes leaves no room to over-write early answers.
• 4Convert your current affairs file into essay material by grouping items under recurring themes such as federalism, technology and governance, and inequality.
• 5Rewrite one previously written answer to half its length to train the concision the marks reward.

• 1Sit two full Prelims mock papers a week under exact conditions, including the two-hour limit and the answer sheet format.
• 2After each mock, sort every wrong answer into three buckets: not known, known but misread, and guessed badly.
• 3Revise your one-page notes for polity, economy and environment in a single pass this week.
• 4Attempt one CSAT paper alongside each General Studies mock so the aptitude paper never goes cold.
• 5Recalculate your attempt strategy from mock data: the number of questions you attempt should be the number where your accuracy stays above the break-even point set by the one-third penalty.

• 1Revise history, geography and science and technology notes in one pass.
• 2Re-attempt every question you got wrong across all mocks, without looking at the explanations first.
• 3Read the last twelve months of current affairs one final time, cutting anything that has not appeared in a mock or a past paper.
• 4Practise map-based and statement-based questions, which is where accuracy drops fastest under time pressure.
• 5Confirm your application details on upsconline.nic.in and download the e-Admit Card as soon as it is released in the week before the exam.

• 1Reach the centre at least 30 minutes before each session; UPSC allows no late entry under any circumstances and requires face authentication at the venue.
• 2Carry the e-Admit Card and the photo identity document whose details you gave in the application, and leave every electronic device at home since no safekeeping is provided.
• 3After Prelims, use UPSC's Question Paper Representation portal if you want to challenge an item; the window runs five days, from the third day after the exam to 6 pm on the seventh.
• 4Start Mains preparation the day after Prelims rather than waiting for the result, because the gap between the two is short.
• 5Move from multiple choice practice to daily answer writing immediately, since the two stages reward completely different skills.

• 1Write one full General Studies paper a week to UPSC's twenty-question, three-hour format and mark yourself against the word limits printed on the paper.
• 2Rotate through General Studies I to IV so no paper goes more than four weeks without a full attempt.
• 3Write both optional papers in full at least once before the Main Examination.
• 4Build the Detailed Application Form content now, because the Personality Test board reads it and every line in it is fair game.
• 5Keep the two qualifying language papers in view: 25 per cent in each is required before any merit paper is even evaluated.
