SSC CPO · Sub-Inspector · General Intelligence and Reasoning

Sub-Inspector in Delhi Police and CAPFs

Fifty reasoning questions — the largest reasoning block any of these exams asks for.

A quarter of Paper-I, sat under a thirty-minute sectional timer that closes on its own. And Paper-I's marks stay on your total all the way to final selection — there is no second reasoning paper to make them up in.

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

Fifty questions, thirty minutes, then the part closes. Paper-I runs a sectional timer of 30 minutes for each of its four parts, so time cannot be borrowed from one section to finish another. Source: SSC Notice of Examination, SI in Delhi Police & CAPFs, 2025, paras 12.1, 12.2 and 16.8.

Fifty questions in thirty minutes. That's recognition, not working out.

In most of these exams reasoning is a gate: twenty or thirty questions in a paper whose marks disappear the moment you're through it. Here it is fifty questions — the largest reasoning block in this family of exams — in a paper whose marks are still being counted when posts are allotted.

The clock is fixed to the section, too. Thirty minutes for fifty 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.

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?

It's free to try — no signup to start, no card, no auto-debit, nothing taken silently. Later, one payment unlocks all the content for a full year — it's a one-time payment, not a subscription, and never an auto-debit. Exact pricing is coming soon. And you'll always be able to try free first — and share the app to keep learning free.

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. Fifty questions, against 25 in SSC CGL Tier 1 and 20 in the GD Constable paper. It's also a quarter of a paper whose 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?

The full app is coming in Hindi — questions and solutions both. For now it's in English. 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.

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. SSC publishes a Notice of Examination each cycle with the application window, and its Tentative Calendar advertises Sub-Inspector in Delhi Police & CAPFs around May, with Paper-I between October and November. Check ssc.gov.in for the current cycle.
