Rajasthan Board Class 9 Science Syllabus

Every student dreams of standing top in examinations. The one who work very hard will only actually top the examination. Excelling in Rajasthan Board Class 9 exam is all about how well you build understanding of the subjects and how structured your study plans are. Structured study plan necessitates syllabus in the course calendar. The Rajasthan Board Class 9 Science Syllabus guides students to properly distribute time on different topics.

Class 9 Science Syllabus under Rajasthan state board is prescribed by the Board of Secondary Education, Rajasthan in short BSER. This state agency works for betterment of secondary education in the state of Rajasthan. The board members form a committee to design syllabus. In order to keep students updated with the latest technology the committee of subject experts revises the RBSE Class 9 Science Syllabus from time to time.

Unit wise Weightage of RBSE Class 9 Science Syllabus

Knowing the chapterwise marks distribution helps students to understand which chapter consists of more weightage from exam point of view. Accordingly student scan devote time to it and prepare for the annual exams. While studying from the Rajasthan Board Class 9 Textbook, students must refer to this marks distribution.
