FAQs on CBSE Class 10 Maths Deleted Syllabus 2025-2026

1. Which topics are removed from CBSE Class 10 Maths syllabus for 2025-2026?
Ans. CBSE has removed several topics including some chapters on real numbers, polynomials, and certain trigonometry sections from the Class 10 Maths curriculum for 2025-2026. The deleted syllabus specifically excludes particular theorems, proofs, and advanced applications to streamline learning. Students should refer to the official CBSE notification and study resources like mind maps or flashcards on EduRev to identify exactly which subtopics are no longer examinable and focus preparation accordingly on remaining chapters.
2. How do deleted topics in CBSE Class 10 Maths affect my board exam preparation?
Ans. Deleted chapters and topics will not appear in your board exams, so studying them wastes valuable time and effort. Candidates should prioritise only the remaining syllabus to maximise marks and revision efficiency.

3. What should I do if I already studied the removed topics from CBSE Class 10 Maths?
Ans. Students who've already covered deleted topics shouldn't panic-foundational concepts from those sections often support remaining chapters in algebra, geometry, and statistics. However, don't spend additional revision time on excluded material. Instead, use that saved time to strengthen concepts in active syllabus areas and solve previous year questions from retained topics to boost exam readiness and confidence.
4. Are the deleted CBSE Class 10 Maths topics important for competitive exams like JEE or NEET?
Ans. Yes, many removed topics-such as advanced trigonometry applications and specific geometric theorems-remain crucial for competitive entrance exams like JEE and NEET.

Students targeting competitive exams should continue studying deleted topics alongside their board syllabus for comprehensive preparation and long-term academic success.
5. Where can I find the complete list of deleted chapters and topics for CBSE Class 10 Maths 2025-2026?
