Buying another book is the easiest thing a worried parent can do, and it is rarely the thing that was missing.
Updated 31 October 2026 · Great Home Tutor · Delhi, Noida and Gurgaon
Most senior maths students already own enough practice material and are using it in the wrong order. The textbook sets the standard, past papers teach the paper, sample papers teach this year's structure, and a thick reference book supplies volume for a student who needs it. Used out of order, the thickest book does the least good.

What each source is actually for
- The prescribed textbook. It defines the standard. Board questions are anchored to it, and the examples in the chapter are not decoration, they are the worked pattern. Every exercise once, including the ones that look too easy to bother with.
- Harder supplementary problems. The exemplar-style material that goes beyond the textbook. Genuinely useful, but after the textbook, not instead of it, and mainly for students who are already comfortable.
- Past board papers. The only source that teaches how the paper behaves: the length, the phrasing, how much working a mark expects. Nothing else substitutes for this.
- This year's official sample paper. Teaches the current structure, which moves from year to year. One paper, read carefully, not a stack.
- School worksheets and past school papers. The closest guide to what the school's own tests will ask, which matters for internal marks.
- A thick reference book. Volume, for a student who needs many repetitions of one type. It is a supply of questions, not a course.
The order that works
Textbook first, and completed rather than sampled. Then past board papers, once enough of the syllabus is taught to make a whole paper possible. Then harder problems on the specific topics that came out weak. Sample papers last, under timed conditions, close to the exam.
A reference book, if used at all, sits alongside this as a tap to be turned on for one topic at a time, not as the spine of the plan. A student working through a reference book cover to cover is doing a great deal of work with no way of telling whether any of it is the work that was needed.
The thing most parents get wrong here. A thick book is bought in April, the first chapter is done three times because it is at the front, and by January the middle of the book has never been opened. The book is not the problem. Starting at page one, every time, is the problem.
How much practice is enough
Not a number. A topic is finished when the child can do an unseen medium question, first attempt, without being prompted on how to start. That is the test, and it can be applied in five minutes.
Counting sums instead produces two failures. Strong students grind through fifty questions on a topic they had already mastered by the tenth, because the target was fifty. Weak students do fifty questions of the type they can already do and quietly avoid the type they cannot, and finish with the same gap they started with and more confidence than before.
When a reference book genuinely earns its place
Three cases. A student preparing for an engineering entrance alongside boards, who needs harder questions than the board syllabus supplies. A student who has genuinely exhausted the textbook and past papers, which is rarer than it sounds. And a specific weak topic where the child needs fifteen similar questions in a row to build a reflex, and the textbook only offers six.
Outside those, another book usually adds choice rather than progress. If your child owns three books for the same subject and works from none of them consistently, the next purchase will not change that.
Home tuition in Dwarka and across the NCR
We teach one-to-one at home across Delhi, Noida and Gurgaon, and live online anywhere. A useful thing to ask any tutor in the first week is which source they intend to work from and why. A tutor who says the textbook first, then past papers, has thought about it. A tutor who arrives with their own photocopied sheets and never opens the child's book may still be good, but you should ask how what they set connects to what the board will ask.
Questions parents ask
Our tutor only uses the textbook. Is that enough?
For a student aiming at a solid board result, largely yes, provided past papers are added once the syllabus allows. For a student aiming at a top percentile or an entrance exam, it is not enough on its own.
Should we buy a reference book for Class 11?
Only after the textbook is genuinely complete, and preferably for a named weak topic rather than in general. Buying one in April, before you know what is weak, is buying before there is a question to answer.
How many past papers should be done?
Enough that the format stops being a surprise, which for most students is somewhere between five and ten, done properly under time and marked strictly. Doing twenty carelessly is worth less than doing six well.
Are online question banks useful?
They are fine as a supply of questions. They are weak at teaching presentation, because they usually mark only the final answer, and in senior maths a large share of the marks is in the working.
My child says the textbook is too easy.
Test the claim before accepting it. Pick the last few questions of a couple of exercises, the ones most students skip, and set them unseen. Quite often the textbook is not too easy; only the first half of each exercise was ever attempted.
