Seven Days Interleaf Graph Notebook — Graph Cum Ruled Practical Copy | 21×23.5 cm | 32 Sheets | Bulk Supply & OEM Manufacturing India

Every Class 9 or Class 11 science student knows the problem: the graph copy is in one bag pocket, the ruled notebook is in another, and switching between the two during a practical session wastes time, creates confusion, and produces records that are harder to follow when it comes to exam revision. The Seven Days Interleaf Graph Notebook solves this problem at the product level. Left page: 5mm precision square graph paper for plotting, diagramming, and data visualisation. Right page: clean single line ruling for observations, calculations, and written records. One notebook. One practical session. Everything in the same place, in the same order, in the format that science and maths teachers actually want to see.

This dual-layout format is what makes the GPN02 fundamentally different from the Seven Days Graph Notebook (GPN01), which uses pure graph ruling throughout. GPN01 is for pure graph work — coordinate geometry, data plotting, technical drawing. The Interleaf Graph Notebook is for practical work — where a student needs to write observations on one side and draw the corresponding graph, circuit diagram, or biological illustration on the other. Two different use cases. Two different products. Both manufactured by CTC Book World at our HSIIDC Kundli facility under ISO-certified quality standards since 1985.

Known by different names in different contexts — "ek side graph, ek side line wali copy" at the local stationery shop; "Interleaf Graph Notebook" in the B2B trade; "Graph Cum Ruled Notebook" on IndiaMART and Amazon; "Practical Graph Copy" in school procurement lists; "Lab Record Book" in college and engineering contexts; "Dual Layout Notebook" or "Alternating Graph and Ruled Notebook" in international export markets. Whatever the name, the product is the same: left graph, right ruled, 32 sheets, 21×23.5 cm, built for the Indian classroom and laboratory environment.

Available for bulk institutional supply, OEM and Private Label manufacturing, CSR stationery programmes, and export to Nepal, USA, UK, UAE, Africa, and beyond.

What Makes the Interleaf Layout the Right Choice for Practical Work

Graph on Left, Ruled on Right — The Natural Practical Format — science and maths practical work consistently requires both graph/diagram work and written observation recording; the interleaf layout puts both on facing pages so students work without interrupting their recording flow; no flipping between two notebooks, no mismatched page references in the final record
5mm Square Graph Ruling on Left Pages — precision-printed 5mm square grid; the standard grid size for school science and maths practicals across CBSE, ICSE, and state boards; suited for coordinate geometry, bar graphs, histograms, circuit diagrams, biology diagrams, and lab data plots
Single Line Ruled on Right Pages — clean, evenly-spaced single line ruling for observation writing, calculation recording, aim and result writing, and all the written components of a practical record
Fundamentally Different from a Pure Graph Copy — GPN01 (Seven Days Graph Notebook) uses graph ruling throughout; GPN02 (this product) uses the interleaf dual layout; schools needing pure graph copies order GPN01; schools needing practical record notebooks order GPN02; both available from CTC Book World in the same bulk supply contract
21×23.5 cm Standard Practical Notebook Size — the accepted size for school science and maths practical notebooks across CBSE, ICSE, and state board curricula in India and Nepal
32 Sheets — Full Term Practical Coverage — 32 sheets gives 32 left-page graph spreads and 32 right-page ruled spreads; adequate for a full academic term of science or maths practical sessions at Class 6–12 level
ISO-Certified Paper Quality — smooth writing surface for pen, pencil, and technical instruments; no bleed-through on either the graph or ruled pages; consistent quality across every batch

Where This Notebook Is Used

School Science Practicals (Class 6–12) — physics experiments with graphs and observations on facing pages; chemistry practical records; biology diagrams with written observations alongside
Mathematics Practicals — coordinate geometry plots on the left, working and explanations on the right; statistical graphs with written analysis on facing pages
Engineering & Polytechnic Colleges — circuit diagram drawing on the left, component observations and readings on the right; fluid mechanics charts alongside written reports
Biology Lab Work — diagram drawing on the left-page graph grid; observation and inference writing on the right-page ruling; a format that matches biology practical record requirements across CBSE and ICSE
Competitive Exam Preparation — IIT-JEE and NEET students using graph and ruled format simultaneously for physics and chemistry problem-solving with both graphical and written components
Government Schools & CSR Programmes — interleaf practical notebooks for government-aided school science labs and corporate CSR educational stationery programmes

Frequently Asked Questions

Q: What is an Interleaf Graph Notebook?

An Interleaf Graph Notebook — also called Graph Cum Ruled Notebook, Practical Graph Copy, or Dual Layout Notebook — alternates two different page types throughout the notebook. In the Seven Days GPN02, the left page of every spread is 5mm square graph paper and the right page is single line ruled paper. This dual layout allows a student to draw graphs, diagrams, or circuit drawings on the left and write observations, calculations, or records on the right — both on facing pages, in one notebook, in the sequence the practical requires.

Q: How is this different from the Seven Days Graph Notebook (GPN01)?

The Seven Days Graph Notebook (GPN01) uses pure graph ruling throughout — every page is 5mm square grid. It is designed for coordinate geometry, data plotting, technical drawing, and pure graph work. The Seven Days Interleaf Graph Notebook (GPN02) alternates left-page graph with right-page ruled — designed specifically for practical work where both graphical and written recording are required simultaneously. Schools needing pure graph copies order GPN01; schools needing practical record notebooks order GPN02. Both are available from CTC Book World and can be consolidated in a single supply contract.

Q: What does "ek side graph, ek side line wali copy" mean?

This is the most common way Indian students and parents ask for this product at local stationery shops — "the copy with graph on one side and lines on the other." It describes exactly the interleaf layout: left page graph, right page ruled. The same product is listed on IndiaMART and Amazon as "Graph Cum Ruled Notebook" or "Interleaf Graph Notebook" and in international markets as "Dual Layout Notebook" or "Alternating Graph and Ruled Notebook." Whatever the name, the product is the same.

Q: Is this notebook suitable for CBSE and ICSE practical examinations?

Yes. The Seven Days Interleaf Graph Notebook meets the practical record notebook requirements of CBSE, ICSE, and state board schools. The 21×23.5 cm size, 5mm graph ruling, and single line ruled alternating layout are accepted across major school boards for science and maths practical sessions. The notebook is in active use in schools affiliated with DAV, DPS, Delhi Police Schools, and ITBP Schools among others.

Q: Can we get the school name or logo printed on the cover?

Yes. Through CTC Book World's OEM and Private Label manufacturing programme, schools and institutions can have their name, logo, and branding printed on the interleaf graph notebook cover. Contact us with your artwork and requirement for a production sample and bulk quotation.
