Which exam are you preparing for?

Pick one: the page will speak to your exam.

The one skill every exam shares

Every exam tests how you think. Train the one skill they all share.

Whatever you prepare for (Railway, SSC, Banking, CUET, CAT, placements), reasoning is the section underneath. Build it now; it transfers to all of them.

Reasoning shows up in nearly every competitive exam in India.

Why · the one skill underneath

Whatever you picked, it comes down to this.

Different exams, different names: the same two families of reasoning underneath.

Verbal reasoning

  • Series & analogies
  • Coding-decoding
  • Blood relations & directions
  • Seating & puzzles
  • Syllogisms, and more…

Non-verbal reasoning

  • Figure series & analogies
  • Mirror & water images
  • Paper folding & cutting
  • Cubes & dice
  • Embedded figures, and more…

The same reasoning runs under every one of them. Master it once.

What · one app, the right method

Not more questions. A better way to build the skill.

A system that adapts to you, so your time goes where you actually need to grow, not just where you're weak.

◎

Adaptive to you

Harder questions as you improve, easier when you slip. Your time goes where it grows you most.

↻

Spaced repetition

Brings a question back right before you'd forget it, so it actually stays.

✎

Recall, not re-reading

You reason it out first, then see the answer. That effort is where learning sticks.

☁

Calm focus

A moment to settle before you start. Less anxiety, more focus.

What · Works offline on Android

Practice anywhere. On Android, practice itself needs no internet.

On Android, all the questions live on your phone, so after install, daily practice costs zero data. The app needs the internet once to start, then at least once a week. In the web app, on a phone or computer, you practise in the browser while you are online.

The thinking behind it

Why it works.

Built on the research on how learning works, and by someone who's spent two decades in it.

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 and young adults from every kind of background in a holistic learning centre.

This app goes far beyond that book: a different, living thing. Everything he's learned about how people actually learn, built into something you practise, not just read.

Common questions

Is there a catch? Do I have to pay?

No catch. It's free to try: no registration to start, no payment, no auto-debit. 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.

Everything's free on Telegram. Why use this?

PDFs give you material. This gives you the method (the right practice, at the right time) that actually builds the skill. And trying it is free.

Which exams does it cover?

Any exam that tests verbal or non-verbal reasoning: RRB, SSC, Banking, NMMS, CUET, CAT, campus placements, defence and more.

क्या यह ऐप हिंदी में है?

हाँ, पूरी तरह। हिंदी चुनिए और पूरी ऐप हिंदी में होगी: सवाल ख़ुद, विकल्प, और हर सवाल के बाद का हल, ऊपर से हिंदी लेबल चढ़ी अंग्रेज़ी ऐप नहीं।

Does it work on my phone?

Yes. The Android app works offline: the questions live on your phone, so practice uses no data. It needs the internet once to start, then at least once a week. Get it on Google Play or the Indus Appstore. You can also practise in the web app, in the browser on your phone or computer, while you are online.

Will it stay free?

Trying it stays free: a full session with no registration, and free days when you sign up. The full library is one of the three plans above, a single payment for its period. It is never a subscription, and nothing is ever taken automatically.
