Boards we cover
CBSE and the state boards Indian students actually sit
Each board gets its own material, because the prescribed textbook, the chapter order and the marking scheme are genuinely different — a UP Board chapter list is not a CBSE chapter list with Hindi headings.

Board exam preparation
Which material to use, and when
Most students read the same notes in June and in February. These are different jobs — here's what actually helps at each stage.
Keep pace with class
- Read chapter notes alongside the lesson
- Work the NCERT exercises as homework
- Take the chapter test the week you finish it
- Ask the Q&A forum when something won't click
Find the gaps
- Check the blueprint — where do the marks sit?
- Work through important questions per chapter
- Attempt full sample papers under time
- Bring a tutor in for the one weak subject
Revise, don't relearn
- One-page revision notes only
- Formula sheets every morning
- Previous year papers, timed, full length
- Stop starting new chapters
How it's written
Board-specific, or it isn't worth reading
A UP Board student handed CBSE notes ends up studying chapters that aren't on their paper. That's why every board gets its own material rather than a shared file with a different heading.
- Written against each board's prescribed textbook and chapter order
- Reviewed by teachers who teach that board
- Updated when the syllabus is revised
- Available in Hindi and English medium
- Pages kept light enough to open on 2G
Always check against your own syllabus
Boards revise syllabi and deleted portions between sessions, sometimes mid-year. Our material states the session it was written for, but your school's circular is the final word. If you spot something out of date, use the report link on any page — we fix and re-date it.
Study material is free to read and download for personal study. It isn't for resale or redistribution.
Questions
Study material, answered
Which boards is the study material available for?
CBSE and Indian state boards — UP Board, Bihar Board, Rajasthan Board, MP Board, Haryana Board, Jharkhand and Uttarakhand, with more added based on student demand. Each board has its own material written against its own prescribed textbook, not a shared file relabelled.
Is the study material free?
Yes. Chapter notes, NCERT solutions, question banks and revision material are free to read and download for personal study. You don't need an account to read them — an account only saves your progress and bookmarks.
Which classes are covered?
Class 6 to Class 12 for CBSE. State board material concentrates on Class 9 to 12, where board examinations and the syllabus differences matter most.
Is material available in Hindi?
Yes. Most material is available in both Hindi and English medium, and for boards that teach primarily in Hindi — such as UP, Bihar and MP — Hindi is the default.
Are NCERT solutions included?
Yes, for every exercise in the prescribed NCERT textbooks, with the working shown step by step rather than only the final answer. Many state boards follow NCERT books directly, so these apply there too.
How do I know the material matches the current syllabus?
Every page states the academic session it was written for, and material is updated when a board revises its syllabus. Boards sometimes announce deleted portions mid-session, so treat your school's circular as the final word and report anything that looks out of date.
Can I download material as a PDF?
Yes. Notes, revision sheets and sample papers can be downloaded for offline study, which is useful where the connection is unreliable. Downloads are for personal study and not for resale or redistribution.
My state board isn't listed. Will you add it?
Very likely. We add boards based on what students ask for. Tell us which board and class you need through the contact form, on +91 94585 49015, or at [email protected].
