Each student dreams of standing at the top of exams. The one who is working really hard is just just going to top the test. Excelling in the Rajasthan Board Class 9 exam is all about how well you are developing understanding of the subjects and how your study plans are planned. Structured program of study includes syllabus in the calendar of courses. The Rajasthan Board Class 9 Science Syllabus directs students to divide time on the various topics properly.
Class 9 Science Syllabus is prescribed by the Board of Secondary Education, Rajasthan, in short, BSER, under the Rajasthan State Council. It state department works for the development of Rajasthan state secondary education. The Board members form a syllabus design committee. The committee of subject experts revises the RBSE Class 9 Science Syllabus from time to time to keep students updated with the latest technology.
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 the exam point of view. Accordingly, a student scan devotes time to it and prepares for the annual exams. While studying from the Rajasthan Board Class 9 Textbook, students must refer to this marks distribution.
