HCS 2026 Prelims: Sherlocking Paper Attempt Strategy

With HCS 2026 Prelims just around the corner, this guide breaks down Neil Sir's Sherlocking method and exactly how to attempt the Prelims paper to maximize your score. The core idea is simple: in a 100-question paper, you do not need to know every answer, you need a method that consistently lands you on the right side of the cut-off. Whether you are sitting for HCS or UPSC Prelims, the same playbook of basic sources, previous-year-question analysis and applied reasoning applies.

Key takeaways

• Sherlocking rests on three pillars: command over basic sources, exhaustive previous-year-question (PYQ) analysis, and the ability to connect both with logical reasoning.
• Roughly 80 to 90 questions in UPSC and many state PCS papers are attemptable if you use Sherlocking liberally rather than relying only on rote recall.
• Pure book-knowledge alone gets most aspirants only 20 to 30 questions; the rest must be cracked through direct or indirect application.
• A "dignified negative" is part of the optimization strategy, attempt the 50-50 questions, accept some will go wrong, and still clear the cut-off.
• The 2024 HCS Prelims cut-off, by Neil Sir's estimate, could not have been above 45 (roughly 40 to 45); no official cut-off was released.
• Mindset matters: a positive, solution-seeking attitude is as crucial as your content knowledge in Prelims.

What is the Sherlocking method?

Sherlocking is the name Neil Sir gives his approach to cracking objective papers. It has three important pillars:

• Basic sources first. These are the resources from which government exam papers are actually set, NCERTs, Laxmikant, Spectrum and similar standard books. Your command over these should be reasonable before anything else.
• Previous year question analysis. Every commission repeats particular patterns again and again, and most state commissions now mimic the UPSC. So analyzing both UPSC PYQs and the relevant state's PYQs is essential.
• Connecting it all. The most important skill is backing yourself with logical reasoning, recognizing when a question sits outside your basic resources, and using the hints embedded in the question to get as close to the answer as possible.

Used together, these pillars let you engage questions you have never formally "studied."

How to actually attempt the paper

The governing rule: attempt as many questions as you can without taking a blind guess. Neil Sir is blunt about the limits of rote knowledge, if you only mark questions because you remember reading them in a book before the paper, you will not cross 20, 25, or at most 30 questions. The remaining 40 to 50-plus questions must be tackled by applying Sherlocking, directly or indirectly.

Do not wait for "I read this in a book"

Consider a question with three statements, where only the first comes straight from a book and you are unsure of the second and third. You cannot adopt the attitude that you will mark a question only if you have read all of it. Commissions simply do not set papers from a single basic resource, so that approach is not tenable today.

Work in iterations and aim for 80 to 90

Solve the paper in two or three passes rather than top to bottom in one go. After his exhaustive PYQ analysis, Neil Sir finds that around 80 to 90 questions are genuinely attemptable in UPSC and many state PCS exams, provided you bring command over basic sources, PYQ awareness and an application-oriented, positive mindset, the kind that hunts for a solution instead of freezing at every unfamiliar question. That mindset shift, he stresses, is especially crucial in Prelims.

The "dignified negative" and the math of clearing the cut-off

Sherlocking will not get you all 100 questions right; after the base of solvable questions, some informed guesswork is unavoidable. This is where the dignified negative comes in. Once you are genuinely 50-50 on a question, you should attempt it. Some hints will mislead you, but across a pool of 100 questions, consistent methodology keeps you on the right side of the cut-off.

The arithmetic makes the point. Negative marking runs at a one-third ratio. Suppose you attempt 85 questions and get at least 55 correct and 30 wrong, the penalty is roughly 10 marks, leaving a net of about 45 out of 100, enough to clear a cut-off of 45. The goal is never to manufacture an imaginary 85 right and 5 wrong, or to promise scores of 170 or 200. As Neil Sir puts it, anyone guaranteeing such scores does not really care about the exam. The honest target is a method that leaves you enough room to make mistakes and still pass.

He also flags questions you should simply skip, in the paper he analyzed, about 10 questions could not be solved without a real methodology, so he set them aside rather than gambling.

Beware the "you'd have scored 180 easily" trap

A pointed warning runs through the video: ignore the commentators who, after the paper, claim you would have crossed 150 or 180 marks if only you had "done it properly." Applying random logic after the fact, with no genuine methodology in front of you, is a cheap trick that does not hold up inside the exam hall. What works is a real, repeatable process applied under pressure.

The free resource for HCS aspirants

As a bonus, Neil Sir prepared two free documents grounded in the same method. The first is a Sherlocking document for the 2024 HCS exam in which he solves all 100 questions using the methodology, marking dignified negatives where appropriate and skipping the roughly 10 unsolvable ones. The second is a crisp revision document built on previous year questions with Haryana-specific information. Both were to be released free of cost over the weekend, with a live problem-solving session on his Telegram group beforehand. Aspirants are encouraged to share them with friends and ask follow-up questions.

Who should watch this

This is for HCS 2026 Prelims aspirants in their final stretch, and equally for UPSC and other state PCS candidates who want a disciplined, score-maximizing way to attempt an objective paper. If you have done your reading but freeze on unfamiliar questions, this strategy is for you.

In short, Prelims is an optimization problem: command your basic sources, internalize PYQ patterns, attempt 80 to 90 questions with applied reasoning, and accept dignified negatives to net past the cut-off.
