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 is built by Ramu Emmadi, a practising Mathematics teacher with 20 years of classroom experience in Telangana state schools. B.Ed, M.Sc Mathematics qualified, every lesson is carefully prepared as a step-by-step PDF — making it easy to follow for both independent learners and classroom instruction. The content is structured to match exactly what board examiners expect, because I have seen what students struggle with after years in the classroom.
