EduBadi covers the complete Mathematics syllabus for Class 8, 9 and 10 across three major curricula — CBSE, the Telangana State Board, and the Andhra Pradesh State Board. Each class is organised chapter by chapter, following the same sequence used in your school textbook. Every chapter has a ready classroom presentation and full written notes for each exercise — no login, no subscription and no cost anywhere on the site.
Not sure which class to pick?
Choose the class that matches what you're currently studying in school, not the class you've completed — EduBadi's chapters follow the same sequence and pacing as a school year, so picking your current class lines lessons up with what's being taught in your classroom right now. If you're revising a previous year or getting ahead for the next one, that's fine too; every class's content stands on its own.
How Class 8, 9 and 10 Mathematics build on each other
- Class 8 lays the algebra and geometry foundations — rational numbers, linear equations, factorisation, and constructions — that everything afterward assumes is solid.
- Class 9 takes those foundations into formal, proof-based geometry and introduces real numbers, coordinate geometry and statistics — the theoretical groundwork Class 10's board exam is built on.
- Class 10 is fully board-exam-focused, covering quadratic equations, trigonometry, mensuration and probability at the depth actually tested in the final CBSE, Telangana and Andhra Pradesh examinations.
Across all three classes, EduBadi currently has 42 chapters and 186 lessons — each with a ready classroom presentation and full written notes.
How this maps to your board
CBSE (NCERT), Telangana State Board (SCERT) and Andhra Pradesh State Board all cover the same core Class 8–10 Mathematics topics, though chapter numbering and a few chapter names differ between textbooks. EduBadi organises lessons by topic rather than by textbook page number, so the same lesson works as a reference no matter which of the three textbooks you're actually holding.
