Why These Notes Work for 2026 Board Exams
What makes chapter-wise revision notes effective?
Revision notes work best when they strip away unnecessary detail and surface only what the CBSE board exam will actually test. These notes, built by the eSaral faculty team trained at IIT Bombay, do exactly that — every mind map and revision video is mapped directly to the CBSE 2026 syllabus, so students spend zero time on out-of-syllabus content.
The 2026 CBSE board exams follow the rationalised NCERT syllabus. Students who revise systematically — topic by topic, using a mix of video revision, visual mind maps, and timed practice — consistently outperform those who re-read textbooks cover to cover. Board toppers from eSaral batches have reported cutting revision time by 40% by switching from passive reading to active revision using videos and mind maps
How are these notes structured?
Each chapter entry contains:
- Revision Video — a focused walkthrough of key concepts, formulas, and solved examples
- Mind Map — a one-page visual summary for last-minute recall
- Linked practice resources — sample papers and previous year questions for the application
After finishing chapter-wise revision, students should solve the NCERT Solutions to reinforce conceptual understanding before attempting full mock tests.
Do not start revision from Chapter 1 and move linearly. Group chapters by difficulty and your own weak areas. Revise your weakest chapters first when your energy is highest, then use the final 3 days before the exam only for formula review and mind maps.
Class 10 Mathematics: Chapter-Wise Revision
| TOPIC | Revision Videos | Mind Maps |
|---|---|---|
| Real Numbers | Revise | Mindmap |
| Polynomials | Revise | Mindmap |
| Pair of Linear Equations in Two Variables | Revise | Mindmap |
| Quadratic Equation | Revise | Mindmap |
| Arithmetic Progressions | Revise | Mindmap |
| Triangles | Revise | Mindmap |
| Coordinate Geometry | Revise | Mindmap |
| Trigonometry | Revise | Mindmap |
| Application Of Trigonometry | Revise | Mindmap |
| Circle | Revise | Mindmap |
| Construction | Revise | Mindmap |
| Area Related to Circle | Revise | Mindmap |
| Surface Area & Volumes | Revise | Mindmap |
| Statistics | Revise | Mindmap |
| Probability | Revise | Mindmap |
Class 10 Science: Chapter-Wise Revision
Science is split across Chemistry, Biology, and Physics. The CBSE board paper draws questions from all three sections, making balanced preparation non-negotiable.
| TOPIC | Revision Videos | Mind Maps |
|---|---|---|
| Chemical Equations and Reactions (Part-1) | Revise | Mindmap |
| Chemical Equations and Reactions(Part-2) | Revise | |
| Acids, Bases, and Salts(Part-1) | Revise | Mindmap |
| Acids, Bases, and Salts(Part 2) | Revise | |
| Metals and Non-Metals | Revise | Mindmap |
| Carbon and Its Compounds | Revise | Mindmap |
| Periodic Classification of Elements | Revise | Mindmap |
| Life Processes | Revise | Mindmap |
| Control and Coordination | Revise | Mindmap |
| How do Organisms Reproduce? | Revise | Mindmap |
| Heredity and Evolution | Revise | Mindmap |
| Light - Reflection & Refraction | Revise | Mindmap |
| The Human Eye and the Colorful World | Revise | Mindmap |
| Magnetic Effects of Electric Current | Revise | Mindmap |
| Sources of Energy | Revise | Mindmap |
| Our Environment | Revise | Mindmap |
| Sustainable Management of Natural Resources | Revise | Mindmap |
Science board papers reward students who can connect concepts. For example, understanding refraction in the Light chapter directly helps you explain the working of the human eye. Always ask "how does this chapter connect to the previous one?" — it makes your answers richer and earns more marks in 5-mark questions.
Focus area: Numericals in Light and Electricity are standard board exam questions. Use the mirror formula, lens formula, and Ohm's Law problems from NCERT Solutions as your primary practice source.

How to Use These Resources at Each Stage of Revision
Not all revision resources should be used in the same way at the same time. Here is a simple stage-wise plan:
| Revision Stage | Timeframe Before Exam | Best Resource to Use |
|---|---|---|
| First Revision | 8–12 weeks before | Full revision videos + NCERT textbook reading |
| Second Revision | 4–7 weeks before | Mind maps + NCERT Solutions chapter-wise |
| Mock Test Phase | 2–4 weeks before | Previous year papers + sample papers |
| Final Revision | Last 3–7 days | Mind maps only + formula sheets |
Students who follow this structured approach — rather than re-reading entire textbooks in the final week — consistently report higher confidence and better time management in the exam hall.
For students planning ahead to Class 11 and JEE, note that the foundations built in Class 10 Physics and Maths directly feed into topics covered in NCERT Solutions for Class 11 Physics and NCERT Solutions for Class 12 Maths

Frequently Asked Questions
Find answers to common questions.
How are revision videos different from reading NCERT textbooks?
Revision videos deliver the same NCERT content in a condensed, exam-focused format — typically in 15–30 minutes per chapter versus the 2–3 hours it takes to re-read a textbook chapter. The videos highlight exactly which concepts, formulas, and question types appear most frequently in CBSE board exams, making them far more efficient for revision than passive re-reading.
Which subjects are covered in these Class 10 revision notes?
Currently, the revision series covers all chapters of Class 10 Mathematics (15 chapters) and Class 10 Science (17 chapters across Chemistry, Biology, and Physics). Each chapter has a dedicated revision video and, where available, a downloadable mind map for last-minute revision.
Are these Class 10 notes aligned with the 2026 CBSE syllabus?
Yes. All revision videos and mind maps on this page are aligned with the rationalised NCERT syllabus as prescribed by CBSE for the 2026 board exams. The content covers only the chapters and topics included in the current CBSE curriculum, so students do not waste time on deleted or out-of-syllabus material.
What should I do after finishing all revision videos?
After completing chapter-wise revision videos and mind maps, the next step is timed practice. Solve at least 5 previous year CBSE Class 10 board papers and 2–3 sample papers under exam conditions. Then return to weak chapters using the mind maps for a final round of review. This combination of revision plus timed practice is what builds both accuracy and speed in board exams.
Do these notes cover the complete Class 10 Science syllabus including Physics chapters?
Yes. All four Physics chapters — Light (Reflection and Refraction), The Human Eye and the Colourful World, Magnetic Effects of Electric Current, and Sources of Energy — are included with dedicated revision videos and mind maps. Electricity, which is a frequently requested chapter, is covered within the Magnetic Effects and related video resources.
Is there a recommended order for using the revision videos?
Start with your weakest chapters rather than Chapter 1. Within each subject, group chapters thematically — for example, all Algebra chapters in Maths together, or all Chemistry chapters in Science together. Watch the revision video first, then test your recall using the mind map. This active recall method is more effective than watching multiple videos in sequence without testing
