# Rajasthan Board Class 9 Maths Syllabus 2020-21

Rajasthan State Board Class 9 syllabus is prescribed by the Board of Secondary Education, Rajasthan, in short RSEB. The board mainly focuses on the promotion and development of secondary education in the state of Rajasthan. The Rajasthan Board Class 9 Maths Syllabus is designed by a group of subject experts who are well trained and experienced in mathematics.

The syllabus is the backbone of every subject. It provides a framework to the students and teachers for the sequential understanding of a subject. Especially when subjects are like Mathematics, referring syllabus is almost unavoidable if he/she is expecting to score high. Rajasthan Board Class 9 Mathematics Syllabus under RSEB incorporates a wide spectrum of topics starting from algebra to geometry. To master mathematics, he/she has to finish practising entire Rajasthan Board Class 9 Textbook. The only most coherent way to achieve this is following syllabus.
