Chapters

In the order of the CBSE curriculum for 2026-27, with the chapter names it uses. The NCERT Ganita Manjari book orders them differently: “NCERT Ch” gives the matching chapter of the book. Every chapter has notes, practice by step, four checkpoints and the places marks are usually lost.

Where the 80 marks come from

CBSE publishes marks by unit, not by chapter (CBSE curriculum 2026-27). The other 20 marks are internal assessment. Your school sets the paper, so check the latest CBSE curriculum document on cbseacademic.nic.in and your school's own exam plan.

How each chapter works

Step 1

Secure the basics

One-mark questions: multiple choice and assertion–reason.

Step 2

Exam standard

Two- and three-mark questions, set out the way the board pattern marks them.

Step 3

Full marks on long answers

Five-mark answers and case studies, written so no step mark slips.

Step 4

95+ stretch

The harder items that separate 95 from 90.

Each step ends in a 3 to 4 question checkpoint. Pass at 80% to move on; results are saved to your Route to 95 and to a linked parent's dashboard.
