SSC CHSL reasoning practice — Master Mental Ability

Why start now

Three marks for seeing it. One more gone for guessing.

In Tier 2, every question in Section-I is worth three marks and a wrong answer costs a full one. So the distance between recognising a pattern and guessing at it is four marks — thirty times over, in the only tier that counts. That gap is where a rank is won, and it is not won in the last week.

Recognition is a reflex, and reflexes are built the way muscle is: a little each day, over months. The right questions in the right order make it faster. More hours at the desk do not — which is exactly why this section rewards method over time served.

And it pays twice. The same skill that answers Tier 1's twenty-five questions is worth ninety marks in Tier 2. Whatever stage of the cycle you're at, the day you start is the day it starts compounding.

What · the exam

Two tiers. Reasoning is in both — only one of them is counted.

Tier 1 is the gate; its normalised score shortlists you and stops there. Tier 2 is the merit list. This is what SSC's own notice sets out.

Tier 1 · the gate

General Intelligence — 25 questions, 50 marks

100 questions · 60 minutes · 0.50 negative

Analogies, series and classification, verbal and non-verbal
Coding and decoding, symbolic and numerical operations, word building
Venn diagrams, drawing inferences, problem solving
Figures — folding and unfolding, embedded figures, pattern completion

One of four parts, and the only one that is pure skill. A quarter of the marks in the tier.

Tier 2 · the merit list

Reasoning and General Intelligence — 30 questions, 90 marks

3 marks a question · 1 mark negative · 30 questions

Same skill, harder questions
Shares a one-hour section with Mathematical Abilities, thirty questions each
Merit is the aggregate of Section-I and Section-II — 360 marks, 90 of them reasoning
The Computer Knowledge Test and the typing or data entry test are qualifying only

Selection is decided on Tier 2 alone.

How · train the section

Two tiers, one list, one skill.

SSC prints the same list twice. The General Intelligence syllabus for Tier 1 and the Reasoning and General Intelligence syllabus for Tier 2 are word for word identical — "questions of both verbal and non-verbal type… Semantic Analogy, Symbolic operations, Symbolic/ Number Analogy, Trends, Figural Analogy, Space Orientation, Semantic Classification, Venn Diagrams, Symbolic/ Number Classification, Drawing inferences, Figural Classification, Punched hole/ pattern-folding & unfolding, Semantic Series, Figural Pattern-folding and completion, Number Series, Embedded figures, Figural Series, Critical Thinking, Problem Solving, Emotional Intelligence, Word Building, Social Intelligence, Coding and de-coding, Numerical operations." One list of thinking skills, not a body of knowledge — built by solving the right questions, the right amount, over time. That is exactly what Master Mental Ability does.

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 in Tier 2.

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 timed hall takes away.

What this doesn't cover: CHSL Tier 1 is four parts and we train one — General Intelligence. English Language, Quantitative Aptitude and General Awareness need their own preparation, and nothing here prepares the Computer Knowledge Test or the typing and data entry skill test, which need a keyboard rather than a reasoning app. Inside reasoning, what the app builds is the core of SSC's own list — analogies, series and classification, coding and decoding, figures, and drawing inferences.

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 CHSL?

No, and no single app is. CHSL is four parts in Tier 1 and four sections in Tier 2; we train General Intelligence. English, Quantitative Aptitude, General Awareness, the Computer Knowledge Test and the typing test all need their own work. What we do, we do properly.

Does reasoning still matter after Tier 1?

More than before. SSC uses your normalised Tier-1 score only to shortlist you for Tier 2, and the merit list is prepared on Tier 2 alone — the aggregate of Section-I and Section-II. Reasoning is 30 of those questions and 90 of those 360 marks, at three marks each with one deducted for a wrong answer. The part that lets you in is the part that sets your rank.

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 — and if you're between cycles, that gap is the most useful preparation time you will get.

Is the app in Hindi?

The full app is coming in Hindi — questions and solutions both. For now it's in English. The exam is unusually generous here: SSC sets CHSL in English, Hindi and 13 more Indian languages — Assamese, Bengali, Gujarati, Kannada, Konkani, Malayalam, Manipuri, Marathi, Odiya, Punjabi, Tamil, Telugu and Urdu — for every part except the English Language ones. It is one of the widest language choices of any exam on this site.

When is the next SSC CHSL, 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's Tentative Calendar for 2026-27 put the CHSL 2026 advertisement in April 2026, applications closing in May, and Tier 1 between July and September 2026; as of mid-August 2026 the Notice of Examination for that cycle has not been published, so the numbers on this page are from the CHSL 2025 notice. SSC publishes a fresh notice each cycle with the exact pattern and window — check ssc.gov.in.
