CBSE Class 10 & 12 Mathematics
CBSE Class 10 and 12 Maths, held to an examiner's standard.
For families aiming for 95 and above: original questions checked twice, marked step by step the way the board marks them, and a clear weekly view of where your child stands.
- Examiner-written
- Every answer independently re-checked
- No ads, no sales calls
Where students lose this mark: forgetting to reject the negative root in context.
Built by someone who has evaluated a CBSE school
Pete Bromfield, the founder, has served on a Council of International Schools (CIS) accreditation evaluation team at a CBSE school, reviewing how teaching and assessment work in practice. He is also a maths specialist across IB, A Level and CBSE and a former Head of Maths. That is the standard every question here is checked against. About Pete →
Every question passes four checks before your child sees it.
Written by a maths expert
Original questions in the board's style (multiple choice, assertion–reason, case study, short and long answer), never copied from textbooks or other sites.
Solved again, independently
A second examiner-level solve, with every numerical answer checked by computer.
Matched to the syllabus
Deleted topics removed, and every question tagged to its chapter and topic in the current CBSE curriculum.
Checked for originality
Anything too close to a textbook exercise or a past board question is rewritten.
If anyone finds an error, we correct it within 48 hours and list it publicly. How we check, and the corrections log →
The last five marks are lost in three places. We train all three.
Method, not just answers
The board awards marks for each correct step. Every solution shows where those marks sit, and every chapter lists where strong students still drop them.
Today's paper, not last decade's
About half the paper is now competency-based: case studies, assertion–reason, real-life problems. Every chapter has them, plus a 95+ stretch step that goes beyond the textbook.
Accuracy under time
Every checkpoint is timed at the board's pace, about 1.5 minutes a mark, and marked against the step mark scheme. Then five full 80-mark sample papers for each class, in the board's pattern.
You always know where your child stands, without having to ask.
- Your dashboard. Every chapter as secure, nearly there or needs work; the next step on the Route to 95; time spent this week.
- A short report every Sunday evening. What went well, the chapters to focus on next, and whether the plan is on track.
- An estimated board-score range. Worked out from timed paper scores and chapter mastery, updated every week. It is an estimate, and we show you exactly how it is calculated.
- Linked with your child's agreement. Your child invites you from their account, or you ask from yours and they accept. You sign in with a link and a one-time code sent to your email.

A clear plan, whichever month you start.
Every chapter in four steps, from the basics to 95+ stretch, each ending in a short checkpoint.
Starting in April
The full route: chapters in the order schools teach them, steps 1 to 3 as you go and step 4 once each chapter is secure.
Starting in October
A late-start route: steps 1 to 3 on every chapter, the highest-weighted units first, then five weeks of timed papers.
The final weeks
Timed papers every week, each followed by redoing every lost mark against the chapter's list of where marks are lost.

Questions parents ask
Can you guarantee 95?
No one honestly can, and we won't. A 95+ needs accurate method, complete working and practice under time; this site trains all three, and your dashboard shows honestly how it is going.
Is it free?
Partly. Chapter notes, formula sheets, official board papers, our sample papers with full step-marking schemes and the first step of every chapter stay free. Every chapter question with its marking scheme and the Route to 95 checkpoints come with CBSE Essentials (₹3,499 a year), which you can try free for 7 days with no card. There is no AI marking yet: you mark answers against the full step-marking scheme. Teachers use the teacher tools free.
Standard or Basic?
Both papers cover the same chapters. Our questions are written to the Standard paper (041), so a Basic (241) student is practising at or above the level of their paper.
How is the estimated score worked out?
From your child's timed sample-paper scores and chapter mastery. It is a range, not a promise, and it updates weekly. The exact calculation.
Does my child need their own account?
Yes, and it links to yours in one of two ways: your child invites you from their account, or you ask from your parent account (by their email or share code) and your child accepts. When you ask, you also confirm you are their parent or guardian, as Indian data law requires for under-18s.
Class 12?
Yes: all 13 Class 12 chapters are on the Class 12 page, each with notes, board-style questions and its own Route to 95.
What if I pay for a plan later and it isn't right for us?
Every plan comes with a 14-day money-back promise: if you're not satisfied, email us within 14 days for a full refund. Refund policy.
