How it works

Four steps.No guesswork.

eTayari is not a pile of PDFs with a login. It is a route through the syllabus — practise, prove it, and see what is still weak — and you can walk the whole of it free.

The SI unit of force is:

Joule
Newton ✓
Watt

Why: force = mass × acceleration, so the unit is kg·m/s² — the newton (N).

The route

Start free, finish exam-ready —all in one place.

Nothing here is locked behind a trial that runs out mid-revision. Steps one to four are the whole loop, and you can repeat it for every chapter you have left.

  1. 1

    Make an account

    Takes seconds, and no card. That alone unlocks every chapter quiz and every past paper we have.

  2. 2

    Practise a chapter

    Pick a subject and a chapter, straight from the board syllabus. Learn mode explains as you go; test mode puts you on the clock.

  3. 3

    Sit a real paper

    Past papers typed out clean and searchable — the actual board exam, not a blurry photo of it.

  4. 4

    Come back tomorrow

    The daily question keeps the habit alive, and your scores show you which chapter still needs work.

Two ways to answer

Understand it first.Then beat the clock.

The same question behaves differently depending on what you need from it. Most students learn a chapter in one mode and then prove it in the other.

Learn mode

Understand it

Answer, then read why. The explanation comes up straight away, while the question is still in your head.

Correct. Force = mass × acceleration, so the unit is the newton (N).

Test mode

Prove it

No explanations, a running clock, and a score at the end — the closest thing to exam day we can give you.

What you get back

You finish with a next move,not just a score.

An explanation, every time

Every quiz question carries a written reason, tied to the syllabus — so a wrong answer teaches you something instead of just costing a mark.

Your weak chapters, named

Scores are broken down by chapter, so revision stops being a guess about where you are losing marks.

A reason to come back

One fresh question a day and a streak worth keeping. Small, but it is what turns revision into a habit.
