Efficient HCS Prelims Strategy for UPSC Aspirants

If you are a UPSC or HCS aspirant wondering how to crack HCS Prelims efficiently, this is a focused, no-nonsense strategy from Neil Sir, who walked into the HCS exam without over-preparing and still secured Rank 93 in 2021. His core message is simple: HCS shares almost the entire UPSC syllabus, so a UPSC aspirant can treat it as a high-value backup and clear it with basic sources plus common sense, not thick compilations. Below is his efficient plan for the final stretch and for the paper itself.

Key takeaways

• The HCS syllabus is almost identical to UPSC, verified against the Gazette notification, so you barely need to study anything extra.
• Anyone selling a guarantee for any competitive exam is either a fool or a liar, keep your distance from both.
• HCS CSAT is similar to UPSC and not yet prone to out-of-syllabus questions, so passing it is not a big deal unless you commit a cardinal blunder.
• HCS has one-fourth negative marking, so attempt boldly but avoid blind guesses; basics plus PYQ analysis make an 85-plus attempt realistic every year.
• Treat HCS like a "bear exam": you only need to outrun your competition, not score 100, because the cut-off follows a bell curve.
• For Haryana-specific prep, the Haryana budget plus basic Wikipedia is enough; skip the heavy scheme compilations.

Why UPSC aspirants should treat HCS as a serious backup

A lot of aspirants are told that giving another exam is a distraction from the IAS dream and that "every day is precious." Neil pushes back hard on this. The brutal reality, he says, is that no preliminary exam is certain, and since each exam runs only once a year, you must optimise the single opportunity you get. Refusing to write HCS in the name of staying "focused" on UPSC often means throwing away a genuine chance.

The exam is relevant for two kinds of candidates: those preparing primarily for state services who keep the others as backup, and UPSC aspirants who see HCS as a backup. For both, the smart move is the same, use your existing UPSC preparation and optimise rather than build a whole new mountain of material.

The HCS syllabus is nearly identical to UPSC

The happiest fact, Neil emphasises, is that the syllabus for UPSC and HCS is essentially the same. He says he did not assert this casually, he filtered it from the Gazette notification and invites you to check it yourself against the UPSC syllabus. Science, current affairs, history, all of it lines up.

That means you do not need to study much extra. There is no need for giant compilations of Haryana's schemes. The CSAT side is also similar to UPSC, and HCS has not yet developed UPSC's habit of asking out-of-syllabus questions. So clearing HCS CSAT is not something to lose sleep over, as long as you stick to the basics and do not make a cardinal blunder (his blunt example: do not effectively sleep through the paper after the first 30 minutes).

How to attack the paper: play the options, not the question

Neil's biggest tactical point is to stop wrestling with the question and start working the options. He insists on proof rather than opinion, and points to a free, roughly two-and-a-half-hour video where he solves a past HCS paper (the 2021 re-exam) so you can see the exact mindset. He also ran a community activity in his Telegram group where the next year's questions were discussed openly, and notes that three people from that effort made the list.

His method for match-type and factual questions:

• Skim the options in about 30 seconds and hunt for the odd one out. Often the options are set so that only one is wrong, three are correct and one is not.
• Use elimination through mutually exclusive choices. When two options are dimensional opposites and one is clearly more inclusive, eliminate the narrower one and the answer often falls out.
• Lean on word formation and everyday knowledge. He illustrates with simple connections, for example knowing that churma is a sweet dish, or using the etymology of a word (like "panch" meaning five) to lock a single pairing in a match-the-following question.
• Read the political angle. Governments like to project comprehensive work, so in a scheme question the option that covers everything (for instance dental, OPD, IPD and diagnostics together) is frequently the intended answer, while each other option leaves something out.

The point is not that the whole paper yields to tricks. You still have to do the basic sources properly and keep your mind open. But endless deliberation kills your attempt, while quick, reasoned elimination lets you clear 90-plus questions.

Marking scheme, how many to attempt, and the bear analogy

The one major difference Neil flags between UPSC and HCS is the marking scheme. HCS has one-fourth negative marking. He personally attempted 100 questions, but explicitly does not recommend that, he was carried away by emotion. On analysis his score was about 10 to 12 marks above the unofficial cut-off, yet he realised he had taken three or four blind guesses and should have attempted around 96 or 97, not 100. The rule he draws: mark options with understanding, and leave only those few questions where there is genuinely no clue. If you have done the basic books properly and analysed previous-year questions, an attempt of 85-plus is realistic every year.

He frames the whole exam with a "bear" analogy. If a bear is chasing you and a friend, you do not need to outrun the bear, only your competition. The cut-off is largely set by a Gaussian (bell) curve of deserving candidates, so a slight edge of 10 to 12 marks over the cut-off is enough. Of 100 questions, roughly 12 to 15 will be unsolvable by common sense, do not cry over those. Concentrate on the 80 to 85 easier ones that comfortably carry you past the cut-off.

Haryana-specific prep and the last-week revision plan

The book list, Neil says, is deliberately minimal, just the basic sources, which most serious aspirants will already have done. The same goes for CSAT, where he recommends solving the previous nine years of questions and points to three CSAT videos he has made for UPSC (the HCS level being equal to, or slightly lighter than, UPSC).

For the genuinely Haryana-specific part, keep it tiny: a little of the Haryana budget plus some basic Wikipedia reading on Haryana. Nothing more. Buying the India Yearbook for its Haryana chapter or memorising thick scheme compilations is, in his view, just a way to waste time.

For the final week, he prescribes only three actions:

1. Revise the basic sources quickly.
2. Solve about three years of previous-year questions.
3. Revise with Lucent.

That, plus common sense and a bit of luck, is more than enough.

Who should watch this

This video is for UPSC aspirants weighing whether to write HCS as a backup, and for HCS-focused candidates who want a lean, efficient last-week plan instead of an overwhelming reading list. It suits anyone who values an evidence-based, common-sense approach to objective papers over "study 14 hours for years" advice.

The throughline is optimisation: the HCS syllabus mirrors UPSC, so trust your basics, practise previous-year questions, and train yourself to play the options under negative marking. If you want to sharpen that objective-paper instinct, build it through structured practice on the Prelims test series, and explore more exam-strategy walkthroughs on the blog. Do the basic sources, apply common sense, and then leave the rest to your effort and a little fate.
