Search any chapter name and you will get thousands of results in a second.
Most of them will teach your child something slightly different from what the exam will ask.
That is the real cost of free material, and it is paid in weeks.
Where should I start looking?
Start with the people who set the paper.
Your child's board publishes its own syllabus, and it is free to read.
NCERT puts its textbooks online, and many state boards do the same for their own books.
There are government-run learning platforms too, and your board's own site will point to the one it uses.
Check your own school's website or class group first.
The teacher may have already shared the exact list.
Past question papers teach more about the exam than any video will.
Go outside these only after you have used what they give.
How do I know it matches the syllabus?
Open the syllabus and the free material side by side.
Then check three things.
- Does it name your board and your class, not just the subject?
- Do the chapter names line up with the textbook contents page?
- Is it dated for a recent year, or dated not at all?
A site that cannot name your board is written for everyone.
It will fit no one.
Foreign material is a common trap.
The topic name matches, but the depth and the notation do not.
What separates useful free material from filler?
Useful material asks your child to do something.
Questions, exercises, worked examples, a page to fill in.
Filler explains and explains, and never asks.
A ninety-minute video with no exercise is entertainment with a syllabus stuck on it.
Look for whether answers are given, and whether they are worked through or just listed.
Watch for the ones that are free until the useful part.
Then they want a sign-up, a phone number and a call from a salesperson.
A genuine free resource lets you read the material before it asks who you are.
Judge it in twenty minutes.
Read a chapter you already know well, and see if it is correct and clear.
If it is wrong on something familiar, it will be wrong on everything else.
Things to Remember
- Start with the board, NCERT, and your own school's shared material.
- Match the chapter names against the textbook contents page.
- Prefer anything with exercises and worked answers.
- Test a new source on a chapter you already know.
- Walk away when it wants your phone number before it shows anything.
