Bu ilova haqida

Online Free Notes is an extension of our blog, onlinefreenotes.com, and provides notes, solutions, and answers for a range of subjects for students in Classes 9 to 12.

The app supports learners studying under various educational boards, including the Nagaland Board of School Education (NBSE), Board of Secondary Education, Assam / Assam Higher Secondary Education Council (SEBA/AHSEC), Tripura Board of Secondary Education (TBSE), Board of Secondary Education, Manipur (BSEM), National Council of Educational Research and Training (NCERT), Indian Certificate of Secondary Education / Indian School Certificate (ICSE/ISC), and West Bengal Board of Secondary Education / West Bengal Council of Higher Secondary Education (WBBSE/WBCHSE).

It offers curriculum-aligned study materials organised by board, subject, and chapter, making it easier for students to review key concepts and prepare for examinations. Detailed, step-by-step solutions help clarify complex topics, while regular updates ensure that the content remains consistent with the latest syllabuses and exam trends.

Additional features include a search function to quickly locate topics, offline access for study (as PDFs) on the move, among others.

The app is free of cost and accessible to all. All the notes available in the app/blog can be used freely through the app/blog. However, some content is exclusively available for registered users.
