Every student dreams of standing top in examinations. The one who works very hard will only actually top the examination. Excelling in Rajasthan Board Class 9 exam is all about how well you build an 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 the 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 chapter wise marks distribution helps students to understand which chapter consists of more weightage from exam point of view. Accordingly, students can 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.
Rajasthan Board Class 9 Science Syllabus
As shown above, the Class 9 Science syllabus is divided into five units. Each unit encompasses different chapters. The major topics that students study in science are about motion, work, force, environment, Organisation in the living world, food, Nature and behaviour etc. Refer below table for detailed syllabus of class 9 Science Rajasthan Board. Moreover, students can download the RBSE 9th Science Syllabus PDF for future reference by clicking on the link below.
