Can You Do It?
My story...
Let's Start
What to prepare and more importantly how to prepare is the general hysteria among all. I bring you a prelims strategy inspired by hard work but evolved over my attempts towards smart work with inputs from other toppers.
- 1Stick to the basic books for all your subjects.
- 2Plan for at least 5 revisions for basics before the D-Day.
- 3Current affairs from any one source with multiple revisions.
- 4PYQs of at least 20 years.
- 5Coaching test series to work as supplement knowledge source and nothing more.
To Read or Not to Read, That is the Question!
Anything that cannot be revised shouldn't be read!
Whether it is your first prelims or you have been scoring < 80 marks in your previous attempts, Basics should be your focus!
-
1Basic books list: Laxmikant · Spectrum · 11th and 12th NCERT for Geography · Any one source for Economics · Shankar IAS for Environment · Art and culture, Ancient and Medieval — Nitin Singhania / Lucent / NCERTs
- 2Current Affairs Monthly magazine — Any 1 source.
- 335–40 questions out of 100 will be solved from the above basics.
- 4Multiple revisions >>> Multiple Resources
- 5Essential > Noise
A good plan is half the work done.
Study Hard, Chill Harder!
While a dedicated preparation is advised by all, most people forget to advise dedicated breaks.
- 1Have a timeline ready till 2 weeks before Prelims.
- 2Try and include 4–5 revisions of basic material in this.
- 3Subsequent revisions would take less time — 45/20/15/10/8 break ups for the timeline can be used to start planning.
- 4Remember to sneak in days where you can cover up the backlog. I find 1:12 a good ratio for backlog clearing to planned days i.e 2–3 days every month.
- 5Have days completely to yourself away from studies. I used to keep my Sunday second half absolutely free for Pizza and Netflix. :)
- 6Lastly, your plan should work for you. Don't forget to improvise and personalise it!
How to Stay Motivated at the End of First Month?
By the time we are one month into dedicated prelims preparation, we find ourselves overwhelmed by the syllabus, disheartened by the coaching test series performance, and with a strong urge to start making excuses.
- 1Accepting that some subjects are more difficult than others and will take time. Often we start with polity or history which are the bulkiest. Shifting to easier subjects now and then helps to stay on top of things.
- 2Start memorising from the very beginning. Don't wait for your 3rd revision to do this.
- 3Being consistent over being accurate for now.
- 4Taking coaching tests as a supplement for how to study rather than judging yourself too hard.
- 5Remembering it is too early to give up!
How to Use PT Test Series to Your Benefit?
- 1Use the basic tests to understand how to read the source material. For instance — only through a polity test a first time aspirant realises that you should learn FR, FD, provisions of a money bill, what is the difference between a finance and money bill etc.
- 2After each test, mark the questions you knew but got wrong. These are the questions you should get right in the next one month. There are always 4–8 such questions.
- 3Mark the questions for which you changed your answers. Always ponder on what made you change the answer whether right or wrong.
- 4Marks in Test series at any stage are not reflective of your PT marks on the final day. But your thought process is. Focus on building the right thinking.
- 5Check your accuracy levels. Now is the time to determine how many questions you will attempt on the final day. I prefer 90+ questions because accuracy can't be 100% for more than 30–35 questions.
CSAT Preparation — How and When
CSAT, though qualifying in nature has delayed selection for a number of good candidates. It's time to demystify this paper!
What is CSAT?
- 1Understanding the nature of this paper: This isn't a CAT level exam. It's simple aptitude and common sense tester.
- 2Benchmarking your performance before jumping into preparation: Before you start solving PnC questions and work-man problems, it is important to understand what you really need. Solve the past 2–3 year question papers starting from 2024. If you are scoring 90/100+, you don't need preparation at all. The less you score, the more you might want to prepare for this paper.
How to qualify CSAT?
- 1Try and maximise your number of questions attempted and diversify the accuracy using both English and Mathematics.
- 2All questions don't require formula, some require common sense. Use it more!
- 3Too much time reading theory won't help, solving previous year questions is again the key.
- 4For someone too uncomfortable with Mathematics — sometimes counting like a child can be more helpful than memorizing the formulas.
When to Prepare for CSAT?
- 1Most candidates will shift the burden of preparing towards the last month. By then it is too late because GS preparation can't take a step back then.
- 2Prepare Now! After you have benchmarked yourself, just once a week for 2 hours is more than enough.
The GS Hack I Swear By!
If from experience of every successful candidate, I had to give you just one hack — it is this!
Solve PYQs.
Often, the time is spent in solving test series, random material prepared by coaching institutes and brooding over the low marks that we score in them. These materials are unscientifically prepared, not mapped to UPSC thought process and also lack innovation and imagination in which UPSC is very good.
To learn at par the standards of UPSC, learn from UPSC. Solve PYQs for as many years as possible and as many times as possible.
What to learn from UPSC:
- 1Understanding the options and elimination techniques that can be deployed in different kind of questions.
- 2The Paper Pattern: If your Set appears too difficult, shifting to Question No. 26 might give you a feel of a new set!
- 3Mapping the kind of questions where risk taking have high probability of failure. These questions to be avoided. Example — Ancient Literature Test written by ___. If you don't know it, you will probably guess it wrong. Leaving such questions is smartness.
- 4Realising that despite the variance in difficulty level of paper every year, 30 questions are always easy. The candidate who solves these 30 rightly is the one who clears prelims every time.
12 Days to Go
What to expect:
- 1Feeling that you are forgetting everything
- 2Extreme highs and lows — one moment you might imagine yourself scoring 130+/clearing IFS cutoff and the next moment unsure of even clearing CSE cutoff
- 3Panic attacks after imagining most of the questions coming from the sections you skipped
- 4Sudden realization that you don't know even the order of Mughals (or Vijaynagara dynasty) when it comes to medieval
- 51–2 test scores in 70s
- 6A few "veterans" giving you gyan on how difficult prelims is and "prelims aise nahi nikalta"
- 7Family/relatives testing you by asking random-est of information
- 8Need for validation on both emotional/intellectual fronts
- 9A few days of low/zero productivity
Just remember one thing, everyone is feeling the same and this is a part of UPSC (of any other exam) process. Try to minimize the last one and be comfortable with others.
Feel the feelings but execute the planned schedule.
May the probability be with you!
— Priyansha Garg, IAS AIR 31The Booklist: Resources Decoded
"What are your sources?" is easily the #1 question in my inbox.
The mistake most aspirants make is treating the booklist as a shopping list. They buy everything and finish nothing. My strategy was different:
Minimal Sources, Maximal Revision.
I am sharing my definitive source list below. These are the exact materials I revised more than 4 times (and sometimes up to 12!) before every single Prelims attempt.
History & Culture
- 1Polity: M. Laxmikanth
- 2Modern History: Spectrum
- 3Ancient & Medieval: Lucent GK + Themes NCERTs
- 4Art & Culture: Nitin Singhania
Geography & Environment
- 1Geography: NCERTs (Class 11 & 12)
- 2Environment: Shankar IAS
Economy & Science
- 1Economy: Sriram IAS
- 2Sci & Tech: No dedicated book
Current & Revision
- 1Current Affairs: Vision IAS Compilations
- 2Quick Revision: Acads IAS Tables & Mnemonics
Pro-Tip: Find your list and lock it. Any "supplement" should only be an increase in the number of revisions, not an increase in the number of books.
In the next few posts, I will drill down into how to read these specific sources effectively. Stay tuned!
The Learning Process: How to Actually Start
We often confuse "sitting at a desk" with "studying." You can clock in 8 hours a day, but if your method is wrong, it won't convert into a single correct answer in the exam hall.
Booklists are easy to find. Knowing how to read them is the real skill.
5 Rules for Effective Learning:
- 1Embrace the Discomfort: Real learning is active, not passive. It is inherently uncomfortable. If it feels too easy, you probably aren't retaining much.
- 2No one remembers a text in one go. You will need multiple readings to actually internalize the material.
- 3Concepts build your foundation, but facts get you the marks. Stop saving facts for the final month. If you aren't memorizing from Day 1, you aren't preparing for Prelims; you're preparing to panic.
- 4Start Memorizing Now: Don't leave facts/mnemonics for the last month before Prelims. Fact memorization starts on Day 1.
- 5PYQs are your Compass: Don't just solve PYQs; use them to learn how to read a textbook. They tell you what to highlight and what to skip.
What's Next? I will now break down this process subject-wise. We will start with the "low-hanging fruits" (portions you can memorize easily) and move to complex concepts to build a holistic preparation strategy.
Decoding Polity: Facts vs. Concepts
Polity (Laxmikanth) is the highest-scoring subject in Prelims, but only if you know how to read it. You cannot just read it cover to cover and expect to remember it. There is active effort and memorization that has to go into it.
You must split your preparation into two distinct buckets: Pure Memorization and Conceptual Understanding.
Part A: Pure Facts
Start memorizing these from Day 1. These are direct questions. You either know them or you don't.
- 1Schedules & Parts: Rote learn them. (Use mnemonics like "TEARS OF OLD PM").
- 2Sources of the Constitution: Which feature came from which country?
- 3Important Articles: specifically 1–51A (Fundamental Rights, DPSP, Fundamental Duties), President, and Parliament.
- 4Writs: Habeas Corpus, Mandamus, etc. (Who issues them and against whom).
- 5Constitutional vs. Non-Constitutional Bodies: Create a comparative table for Composition, Tenure, Removal, and Function. Don't read these chapters individually; read them comparatively.
Part B: The Concepts
These require logic. Don't memorize; understand the 'Why' and the 'Interlinking'.
- 1Basic Structure & Preamble: Understand the keywords (Sovereign, Republic, Liberty).
- 2Federalism: Center-State relations, Legislative/Administrative/Financial divisions.
- 3Parliamentary System: How a Bill becomes an Act, Budget process, Motion types (Censure vs. No Confidence).
- 4Emergency Provisions: The nuance between National Emergency vs. President's Rule.
Testing: Solve PYQs immediately after finishing a conceptual block to see if you understood the nuance.
Decoding Modern History: Target the Low-Hanging Fruits
A significant portion of the questions in Prelims from Modern History are purely factual. The questions are direct. You either know the answer or you don't.
Part A: Topics that require rote memorization.
Use the tables at the back of the book (Appendices) and revise them frequently.
-
1Organisations (Socio-Religious & Political)
- What to memorize: Name of the Organization, Year of Formation, Founder and Main Agenda (Goal).
- Focus: Pay special attention to Pre-Congress associations (e.g., Landholders' Society) and Revolutionary groups.
-
2Newspapers, Journals & Books
- What to memorize: Name of the publication and the Author/Editor.
- Focus: Map the literary works to the specific freedom fighter. Questions often ask to match the personality with their journal (e.g., Al-Hilal – Abul Kalam Azad; Commonweal – Annie Besant).
-
3Movements (Tribal, Peasant & Civil Uprisings)
- What to memorize: The Region (Map location), The Leader and the immediate Cause.
- Focus: Distinguish between 19th-century tribal revolts (e.g., Santhal, Munda) and 20th-century peasant movements (e.g., Kisan Sabhas).
-
4Viceroys and Governor-Generals
- What to memorize: The specific tenure and the major events that occurred under them.
- Focus: Use the list given at the back of Spectrum as a Timeline Anchor. Do not just memorize names; use them to establish the chronology. (e.g., If you know the Ilbert Bill happened under Ripon, you automatically know the timeframe).
Implementation: Don't clutter your main study time with these lists. These are your "30-minute daily drill" topics.
Decoding Modern History: Mastering the Concepts
While Part A (Factual Data) helps you answer direct match-the-following questions, Part B (Concepts) is crucial for the statement-based questions with a larger focus on the "Who, Where, and Why."
Part B: The Conceptual Framework
Strategy: Read these chapters to build a narrative. Focus on cause-and-effect relationships rather than isolated facts.
-
1Mass Movements: Analyze it through the Regional & Demographic lens, which is a favorite area for PYQs.
- Regional Spread: Who led the movement in specific regions? (e.g., In Salt Satyagraha: C. Rajagopalachari in Tamil Nadu, K. Kelappan in Malabar).
- Participation: Who participated? (Did women join? Did the working class join? Did the princely states join?)
- Demands: What were the specific demands? (e.g., The 11 points of Gandhi before Civil Disobedience).
- Response: How did the British react? (Concessions vs. Brutal suppression).
-
2Constitutional Evolution: Do not memorize the Acts (1909, 1919, 1935) in isolation — compare instead.
- Focus on Trends: Trace the trajectory of specific features.
- Franchise: How did voting rights expand?
- Executive vs. Legislature: How did the control of the legislature over the executive increase?
- Center-State Relations: Trace the shift from Unitary (1858) to Federal (1935) structures.
- PYQ e.g: "Dyarchy" in 1919 (Provinces) vs. 1935 (Center).
-
3Ideological Shifts: Understand the transition of thought/approach.
- Methodology: How did the method of struggle evolve? (Petitioning → Passive Resistance → Mass Satyagraha → "Do or Die").
- Revolutionary Trends: Differentiate between Phase 1 (Individual Heroism/Sacrifice) and Phase 2 (Socialist leaning/HRA/HSRA). Understand why Bhagat Singh's ideology was different from the earlier revolutionaries.
-
4British Policies: Analyze the colonial footprint on Indian society.
- Land Revenue: Compare Zamindari, Ryotwari, and Mahalwari. Who was the owner? Who paid the tax? What was the impact on the peasant?
- Education: Orientalists vs. Anglicists. What was the objective of the Dispatch of 1854 vs. the Act of 1904?
When reading a chapter keep the PYQs open. This will help you know what has been asked and how.
Decoding Geography: The "Binge" Strategy for Mapwork
While everyone asks you to "do mapwork," no one really tells you how. It is basically cramming facts, and for many, the standard advice of "15 minutes a day" just doesn't work. It breaks the flow.
My Approach: The 2-Day Binge 🎧
For me, the best approach was immersion. I wouldn't drag it out. Instead, I would dedicate 2 full days to it.
The Setup: Music + Plain Paper + Pen. The Method: Draw, label, repeat. Active recall (drawing from memory) beats passive staring every time.
What exactly do you memorize? Focus on these 5 buckets and then add as and when needed.
-
1Places in News (International)
- What to look for: Not just the specific city/place, but the rough idea of the region.
- The Checklist: Neighboring countries, nearby cities, and access to the sea. (e.g., If Ukraine is in the news, know its borders with Poland, Romania, etc.).
-
2Important Water Bodies/Regions (Global)
- Focus: Bordering countries are the favorite question type.
- Details: Memorize the countries touching the Caspian Sea, Black Sea, Red Sea, and Mediterranean.
- Chokepoints: Important Straits (Hormuz, Malacca, Bab-el-Mandeb) and Gulfs.
-
3Indian Physical Mapping (Rivers & Mountains)
- The Rule of Order: Don't memorize randomly. You must know the sequence.
- North to South: (e.g., Karakoram → Ladakh → Zaskar → Pir Panjal).
- Left vs. Right Bank: For major rivers like Ganga, Godavari, and Krishna.
- Proximity: Which city lies on which river bank?
-
4Indian Economic Geography
- Focus: Mineral Belts and Industrial clusters.
- Logic: Connect the resource to the industry (e.g., Iron ore mines in Odisha → Steel plants nearby).
-
5Protected Areas (Environment Linkage)
- Focus: National Parks, Wildlife Sanctuaries, and Wetlands that were in the news.
- Details: Know the State + The River passing through it + Any flagship species found there.
Summary: Put on your music, grab a pen and finish the bulk of it in one go.
Decoding Ancient & Medieval: The "Fact-Heavy" Strategy
Ancient and Medieval History are the most volatile subjects in the syllabus. You memorize a dynasty today and you will definitely forget their capital tomorrow. It is factually dense. Hence, there is very little "concept" and a lot of "cramming." Also, the Cost-Benefit ratio is low.
Lucent GK + Themes NCERTs were my books.
-
1Lucent is factual and will definitely require more than 5–6 reads to make some sense.
- You can start with terminologies/tables/books and authors/battles.
-
2Themes NCERT
- Focus on the Boxes, Images and Captions. If there is a map of Mauryan inscriptions, memorize the locations.
-
3Identify the most repeated topics:
- Chronology
- Administration
- Religious sects: Councils, Texts, Sects like Hinayana/Mahayana
- Types of officers/terminology used by different kingdoms: e.g., Samaharta, Sannidhata
-
4Solve Questions:
- Randomly solving tests is helpful for active recollection. You will get them wrong and then you will remember it.
- Reverse Learning will be helpful.
PS: Spending too much time on reading dense books might not be very useful. Most people will get most questions wrong because India has very rich ancient and medieval history and no one can know it enough. Stick to the basics!!
Decoding Environment: Focus on These 4 Pillars
Average time needed: 3–4 days.
-
1The Basics (Ecology & Agriculture) 🌿
- Ecosystem functions, Food Chains, Pyramids and Cycles (Nitrogen/Carbon).
- Cropping patterns, Sustainable agriculture (Permaculture, Zero Budget Natural Farming) and Technologies (System of Rice Intensification).
-
2Biodiversity & Climate Change 🐾
- Understand the phenomena — Global Warming, Ocean Acidification, Coral Bleaching and Ozone Depletion.
- Focus on "Flagship Species" (Cheetah, Great Indian Bustard, Dugong). Know their IUCN status + Habitat.
- Protected Areas: National Parks, Wildlife Sanctuaries (WLS) and Tiger Reserves that were in the news.
-
3Organizations & Funds 🇺🇳
- International: UNFCCC, CBD, UNCCD, IUCN. Focus: Know the Conferences of Parties (COPs), the Funds (GEF, GCF, Adaptation Fund) and the Reports they publish.
- National: NGT, CPCB, WCCB, NBA. Focus: Statutory vs. Non-Statutory. Who heads it? What are its powers?
-
4Acts & Laws 📜
- The Big 4: Wildlife Protection Act, 1972 (Schedules are crucial) · Environment Protection Act, 1986 · Forest Conservation Act, 1980 (and recent amendments) · Biodiversity Act, 2002.
- The Rules: Waste Management Rules (Plastic, E-waste, Solid Waste). Know the targets and the bans.
Master these core areas and you'll be prepared for 70–80% of environmental questions. Beyond that, the returns start to diminish. Focus your time where it matters most and then supplement strategically as needed.
