About EduBadi
Free, step-by-step Mathematics lessons for Class 8, 9 and 10 — built by a teacher, not a textbook publisher.
Our Mission
EduBadi was created with one simple belief — every student deserves access to quality education, regardless of where they live or what they can afford. We provide free, step-by-step Mathematics lessons for Class 8, 9 and 10 students across CBSE, Telangana State Board and Andhra Pradesh State Board.
Built by a Teacher
EduBadi's lesson content is written by Ramu Emmadi, a practising Mathematics teacher with 32 years of classroom experience in Telangana state schools (B.Ed, M.Sc Mathematics). Every lesson is original work, carefully prepared as a step-by-step PDF and presentation — making it easy to follow for both independent learners and classroom instruction. The content is structured around what students actually struggle with, because that struggle has been watched first-hand, year after year, in a real classroom.
