SSC CPO · Sub-Inspector · General Intelligence and Reasoning

Sub-Inspector in Delhi Police and CAPFs

Reasoning is the only subject SSC asks you twice.

Twenty-five questions in Paper-I, and twenty more in Paper-II where each one is worth double. Both papers' marks carry all the way to final selection, so the same skill is scored twice and counted twice.

For graduates preparing for Sub-Inspector posts in Delhi Police and the Central Armed Police Forces.

Twenty-five questions, fifteen minutes, then the part closes. Paper-I runs a sectional timer of 15 minutes for each of its four parts, so time cannot be borrowed from one section to finish another.

Twenty-five questions in fifteen minutes. That's recognition, not working out.

In most of these exams reasoning is a gate: a block of questions in a paper whose marks disappear the moment you're through it. Here it is asked twice — twenty-five questions in Paper-I and twenty more in Paper-II — in a paper whose marks are still being counted when posts are allotted.

The clock is fixed to the section, too. Fifteen minutes for twenty-five questions, then Part I closes and General Knowledge begins whether you were finished or not. There is no saving a hard one for the end, so the pattern has to be visible on sight.

Seeing it on sight is a trained reflex, built in months of short, spaced practice — never in a final fortnight. Whatever stage of the cycle you're at, the day you start is the day it starts compounding.

What · the exam

One paper is scored. The rest of the process filters.

Paper-I and Paper-II decide selection between them. The physical tests and the medical are mandatory, but qualifying in nature.

Scored

Paper-I · Part I · General Intelligence and Reasoning

25 questions · 25 marks · 15-minute sectional timer

  • 100 questions and 100 marks across the paper, in one hour
  • Set in Hindi and English, as Parts II and III are
  • 0.25 deducted for a wrong answer
A quarter of the paper, and the only part that is pure skill.
Qualifying

PST / PET, Paper-II and the medical

All stages mandatory

Nothing on this side is prepared on a phone.
How · train the section

The biggest reasoning section in these exams, trained properly.

General Intelligence and Reasoning isn't a syllabus you can read. It's a thinking skill, built by practising the right questions, the right amount, over time. That's exactly what Master Mental Ability does — and SSC's own syllabus calls this part "questions of both verbal and non-verbal type", which is precisely what the app trains.

Adapts to you

Harder as you improve, easier when you slip. No time wasted on what you've already got.

↻

Back before you forget

Spaced repetition returns a question right as it's about to fade — so it's still there on exam day.

✎

Solve first, then see

You reason it out before the answer shows. That effort is where recognition gets built.

☁

Calm before the clock

A moment to settle before each session. The same calm a sectional timer takes away.

What this doesn't cover: Paper-I has four parts and we train one — General Intelligence and Reasoning. General Knowledge, Quantitative Aptitude and English need their own preparation, and Paper-II is entirely English. The PST, PET and medical stages are physical, and nothing on a phone prepares you for them. Even inside reasoning, the clerical-speed items on SSC's list — indexing, address matching, date and city matching, centre-code classification — along with emotional and social intelligence, aren't what this app is for. It trains the reasoning core: analogies, series, classification, coding, figures and inference.

Built by

In 2007, in his second year at IIT Delhi, Vineesh wrote a book — Master Mental Ability in 30 Days. It has sold year after year ever since, without the publisher ever marketing it.

In the years since, he built other learning products and spent a decade working with children of every background in a holistic learning centre.

This app goes far beyond that book — everything he's learned about how people actually learn, built into something you practise, not just read.

Your questions

Common questions

Is it really free? Will money get taken from my account?

Free to try — no signup to start, no card, no auto-debit, nothing taken silently. When you want the full library there are three plans, by length: ₹499 for three months, ₹699 for six, ₹999 for a year. Each is a single payment for that period, not a subscription — when it ends we ask you, and nothing is ever taken automatically. You can also keep learning free by sharing the app, and you can always try before paying anything.

Is this app enough to clear SSC CPO?

No — and no single app is. We train one of Paper-I's four parts. General Knowledge, Quantitative Aptitude and English need their own preparation, Paper-II is entirely English, and the physical and medical stages need the ground and the gym. What we do, we do properly.

Is the reasoning section bigger here than in other SSC exams?

Yes — and twice. Twenty-five questions in Paper-I and twenty more in Paper-II, where each is worth two marks rather than one: forty-five reasoning questions and sixty-five reasoning marks across the two papers. Both papers' marks count towards final selection, rather than a screening paper whose marks stop mattering once you're through.

I have very little time before my exam. Is this any use?

Some. Practice always beats no practice. But be honest with yourself about what 36 seconds a question means: recognition is built over months, not in a week. Start anyway — the next cycle is closer than it feels.

Is the app in Hindi?

Yes — fully. Choose Hindi and the whole app is Hindi: the questions themselves, the options, and the explanation after each one — not an English app with Hindi labels around it. Worth knowing either way: SSC sets Parts I, II and III of Paper-I in Hindi and English, so the reasoning part is available in both.

How much internet does it need?

On the Android app, very little. The questions are on your phone, so you can practise on a train, in a village with no signal, on a phone with no data pack. It needs the internet once to start, then at least once a week to keep your access active; that is also when your progress is saved online. If it goes longer than a week without connecting, practice pauses until it does, and nothing is lost. The web app needs a connection while you practise.

When is the next SSC CPO, and where do I apply?

Only on the Staff Selection Commission's own website, ssc.gov.in — never through an agent and never through us. Applications for the 2026 cycle closed on 30 September 2026. SSC's schedule notice of 1 October 2026 puts the computer-based examination between 20 and 28 November 2026. SSC publishes a fresh Notice of Examination each cycle with the application window and the exam pattern. Check ssc.gov.in for the current cycle.
