UPSC-2027 by CSE Topper

Standard textbooks, Govt websites, govt press releases and reputed newspapers.

Mistakes I Think You Might Be Making •⁠  ⁠Relying entirely on a foundation course(1 year, 2 year or 5 year whatever) •⁠  ⁠Taking an attempt before your preparation is ready. With the change in rules, you might get stuck in a service you don’t want, if you enter the cycle too early. •⁠  ⁠Entering the examination cycle without completing the syllabus, preparing notes, and establishing a basic answer writing routine. •⁠  ⁠Memorising information mechanically without developing genuine conceptual understanding. •⁠  ⁠Assuming you cannot succeed and gradually turning that belief into reality. •⁠  ⁠Worrying about why you cannot study, when the deeper issue may be that you never truly wanted to pursue this examination. •⁠  ⁠Treating newspapers casually instead of using them to build issue-based understanding. •⁠  ⁠Failing to understand the demand of the question paper and therefore studying everything indiscriminately. •⁠  ⁠Revising passively instead of actively recalling and testing your knowledge. •⁠  ⁠Focusing more on marks in mains tests than on feedback by mentor. •⁠  ⁠Writing too few answers. If you carefully study what successful candidates actually did, the volume of answer writing is often much higher than most aspirants assume. •⁠  ⁠Assuming that your teacher is the best authority although you are studying it for the first time. At that stage, you are still a novice and may not yet be able to judge quality. •⁠  ⁠Neglecting your physical and mental health during preparation. •⁠  ⁠Hankering after coaching with largest selection - remember even if they are true - selection is a game of statistics - if 1000 students enrolled in a course after clearing pre, some will anyway clear it.

Continued #csetopperPROTIP The best results are produced when you are naturally good at one way of thinking while you consciously work hard to make the other way of thinking part of your routine. I consider Vikram Grewal(AIR 51, CSE 2018) to be the perfect example of someone with a “Abstract Thinking Mind” working hard to get better at generating more points through notes consolidation. Look at his notes and you’ll understand.

In one of his interviews he said that he pushed himself to think in the Intro-Body- Conclusion format for every topic of the syllabus.

For those with Abstract thinking as their forte can use the following methods to get good at acing this exam: 1. If possible find people to study in groups of 3-4. You must find someone who is more disciplined than you to get you to make those notes needed for Mains in particular. 2. Do brainstorming on Mains questions by placing it in your daily routine. Go through the reverse engineering route, look at a lot of topper and think of points before going through toppers’ answers . Make note of new points that you learned. 3. Make mnemonics for generating points for every broad topic in syllabus. E.g. TIPS for GS-3, TEEP DOST for IR etc. 4. Keep asking Prelims questions to your friends and analyse PYQs to find themes for Prelims and Mains which will repeat. 5. Consciously make a rule that you’ll Make Notes of everything that you read. Note taking will be one habit that will take you far. For those who are Naturally good at linear thinking need to alter their ways in the following way(while these people have more chances of acing this exam, they tend to work hard without having a sound plan of action creating troubles for them) Gaurav Budania is an example of a naturally good “Linear Thinking Mind” working hard to channelise his energy and skill properly to ace the exam. 1. Make a detailed schedule for the time that is left and allot time for note taking, answer writing , brainstorming and Prelims preparation(equal importance to everything). 2. Make sure that you don’t overspend time on a particular topic. Make sure that you have answer writing placed in your routine. 3. You may not study in a group but stay in touch with 3-4 people who may be studying on your own to be in touch with the exam process. 4. Solve Prelims Mocks and actively think of questions which may appear in Prelims and Mains exam based on the trends of PYQs.(Predict questions) 5. To tackle the questions in Prelims in particular which will require to connect the abstract dots, sit in a group of 2-3 and ask questions to each other which may appear in the exam. Make notes from Prelims Perspective as well, particularly from the mocks.

Pro Tip for UPSC Based on my decade long experience of observing, guiding and preparing with UPSC Toppers and aspirants, I classify Serious UPSC aspirants into two broad categories. It is important to know which category you fall in, to make your preparation more streamlined. 1️⃣ People with Minds having really good abstract thinking 2️⃣ People with Minds having really good linear thinking Those who are good at abstract thinking have the following characteristics 1. They inter relate everything that they have read and known since school time. Everything from newspaper to movies to YouTube videos, easily becomes a part of their knowledge base. 2. They find it really difficult to maintain a daily routine and often find it difficult to study alone. 3. They thrive while listening to discussions and being part of debates around socio-political issues. People with abstract thinking are really good at tackling the Prelims exam and do really well at the interview stage. They are reasonably better in writing Essays as well. Gs Mains in particular is something that troubles them a lot. The 2nd category of people having a Mind with linear thinking have the following characteristics: 1. They thrive around having a routine and find it easy to make detailed notes and write tests on a regular basis. 2. They can sit for long hours and find it more comfortable to study alone. They find it easy to limit themselves to the need and syallabus of the exam and consciously avoid debates and discussions to save time. 3. They find it difficult to answer random questions in Prelims and Essay paper, but are really good at dealing with predictable themes. People with linear minds are generally reasonably good at GS Mains and Optional papers. They write good number of points in Mains answers(taking out one point from another and so on) and more often than not score really well in Mains. Interview, Essay and Prelims are the places where they struggle. To be continued in next post(about what should be the course of action for both the categories of people for having a good shot at CSE 2024) .. #csetopperPROTIP

The post includes the basic static sources that you’ll have to study. Irrespective of the coaching you have taken it is always wise to refer to the standard sources for static.

💯One key thing to remember for serious 2026 aspirats: The tricks, tips, important themes are only useful if you have done enough revisions till Prelims of your static sources. Revisions of the static sources which includes the following must at least be done twice in the remaining days before Prelims: 1. Laxmikant for polity 2. NCERTs of 11th and 12th for Geography 3. One Source to cover the Economy Static(NCERT/Mrunal/Sriram's book etc) 4. PMF or Shankar for Environment 5. Old NCERTs/New NCERTs/Tamiladu 11th,12th books for Ancient and Medieval 6. Singhania for Art and Culture 7. Spectrum etc for Modern 8. Orient or Oxford Atlas for Mapping Can use 1-3 maps posted everyday in Free Mapping Series(Click to follow`) in your schdule 9. One Basic Source for S&T(Can be class notes, PT365 of the subject etc) Before you have a schdule and method to revise these twice before the exam, every other flashy marathon, video, Note is of no use. Don't get distracted and focus on the non negotiables(Static) first and then add edge by practicing,PYQs, Strengthening high Yield themes, Improving with more mocks and revising current. don't waste time watching random marathon videos, time is the only thing that is limited(use it to revise books), flashy-clickbait-get 125+ vidoes are unlimited(The use value of this new information from such videos is very small since there is negligible possibility of a revision coming through.) Apply common sense and stick to a solid plan with Highest priority and time allocated for static revision.

Pro Tip for 2027(Year long Prep for Mains): Irrespective of the time that you have already spent in UPSC Prep, if you have more than 12 months before attempting the Prelims paper, the following boxes have to be ticked: Step-1: Building Basic Understanding: Before making notes for any subject, you must complete at least one thorough reading of standard/core sources. For instance before attempting to make notes from Prelims or mains perspective for polity, you must read/study the book of laxmikant(the core source of polity) at least once. 2. Step-2: Making/Consolidating Mains Topic/Theme wise Notes: The 2nd step is to make/consolidate notes from Mains perspective for a particular subject. • Notes from coaching, YouTube, or Telegram are not enough on their own. • You must refine, enrich, and organize them topic-wise.E.g: Notes on the topic of Federalism for GS-2(should have content from Laxmikant, examples from News, topper copies, you can google, use AI to make this content). 3. Once these two steps are done, you can start attempting mock tests(ideally start mini tests of 2-7 questions from PYQs/Test Series) on a regular basis. The same time should be used to read+prepare/consolidate notes for the next subject. Meaning that once you are done with one subject with the first two steps you can practice answer writing for that subject and simultaneously complete the first two steps for the next topic. This cycle should continue until you finish the steps for all the subjects in GS papers and Optional. 4. While you’re writing answers, you must be simultaneously improving your notes based on the feedback/analysis received/done. The ideal timeline for finishing these three steps for GS as well as Optional is a maximum of seven months and minimum of 5 months depending on different factors. 5. Following these three steps makes you worthy of giving a good attempt at next Mains and preparing foundation for Prelims. 6. The most crucial 4th step comes after finishing the first three crucial steps, which is to step up your content and answer enrichment/value addition/presentation improvement to the level of toppers. The 4th step is something that differentiates the mains copies of people scoring ~700-750 and 800+ 7. Following the first 3 steps makes you capable to compete with your peers in mock tests or inculcate feedback of mentors/teachers/guides/your intellect more effectively. Here begins the process of ultra refinement of your mains notes/improvement of interlinkage of dimensions/exercises to inculcate more points/predicting questions and making refined intros, conclusions, value addition points along with practice. The practice at this level makes you feel that the result is within your reach and your efforts seems to materialising.

Pro Tip for Prelims In 2024 CSE prelims, 8 questions worth 16 marks came directly from class 11 & 12th geography ncert. UPSC did not even modify the statements, instead just copy pasted. Before reading anything, read ncert first for geography & history. The Return on time invested is quite high for the NCERTs of History and Geography.

A brief timeline for my preparation (helpful for beginners by Harsh Nehara) July’22-Nov’22 : Read NCERT and few basic books of GS to build a foundation, also read a bit of anthropology. Dec’22- March’23 : Started anthro note making and sole focus on optional. April’23- Dec’23 : Finished 75% of GS mains notes and 100% optional notes and first revision of optional. Also read all standard books atleast twice. Also wrote few half length tests and anthro answers. Jan’24- June’24 : 3/4 revisions of prelims and tests along with CSAT. Cleared prelims in first attempt. July’24- August’24 : Full fledged mains revision and finished off remaining notes. For optional, I compiled my 1200 page notes into 350 page short notes. Couldn’t write many tests for optional and wrote 2-3 GS tests. Ended up qualifying mains. Sep’24- Nov’24 : Nothing, just enjoyed life while going through optional notes. Dec’24- March’25 : cleared mains and prepared for Interview. Post interview in march, I did nothing, tried to study but couldn’t till result was out on 22 April. April’25- May’25 : prelims preparation for a month. Cleared it with decent marks. June’25- Aug’25 : Full GS and optional answer writing with my friends. Tests, revision and compiled my GS notes. Sep’25- Nov’25 : Tried to study for Forest service mains but was too exhausted to cover two new optionals thus ended up skipping IFoS mains as I felt confident with CSE. Dec’25 : Interview on 2nd day. Post interview did nothing much and just waited for results. 6 March 2026 : Finally after 3 years, 8 months and 5 days of first ever sitting in a library, I got AIR 74 and expect to be allotted to the IAS.

You avoid reading topper copies as these contain the best of the points from more than 800 topper copies of the previous years including the 2023 ones.

#csetopperPROTIP Those who have just begun, need to know this one thing. Practicing objective questions will only allow you to get past that barrier. Even if the next Prelims is some 11months away, you must develop the practice of solving atleast 15 questions daily. Do the practice only from reliable sources. There are 100s of telegram channels who make you do daily practice, by clicking on 1 out of 4 questions. Most of them are bogus and post useless questions. Make it part of your schedule. Don't just practice. Make 1 line note of the new things that you learn from every objective question that you practice. If you do that every day and revise your learnings once in every 7 days, your knowledge about will compound and will gain substantially in terms of marks. Starting 3 or 5 months ago is not the solution if you are far behind. In prelims, out of all the 10-12 thousand people who clear it, more than 8 thousand are those who have cleared it once before. You know that from experience that people who clear prelims once, rarely do they fail in the next attempt. That way only 1 in every 500 people will be people are first timers in mains every year. The competition is way beyond what you think it is. Don't take it lightly. Start practicing today to get an edge over those 499 others. Only the fittest will survive here. @csetopper_helpline for Queries and Enrolment!

Pro Tip for Beginners: Note-Making for Mains 1. If making online notes: keep an eye on the word count of what you’re collecting. Online notes can easily swell into bulky books without you even realizing it. One theme shouldn’t be having more than 500 words of notes. 2. If you prefer offline notes: use loose sheets. Limit each theme to a maximum of 4 pages (on average, aim for 1.5 pages). Always leave margins, about 1/6th of the page, so you can later add current affairs or value additions. Use a scale to draw the margin lines and then take notes. 3. Daily revision is non-negotiable. Spend at least 15 minutes revising your mains notes every day. The order doesn’t matter much, but the consistency does. The most important thing to note for beginners is that note taking is the most efficient way of gaining command over Mains writing. It is the essential but a tough first step. Answer writing should follow to get those notes ingrained into your answer writing.
