    CBSE Class 9 Science Syllabus

    CBSE has released the syllabus for all subjects of Class 9. In this article you will get the complete syllabus of CBSE Class 9 Science and know all the topics to be studied for the annual exams 2018-2019.

    As per the assessment scheme introduced in Class 9 from the last session, 2017-18, now class 9 students are assessed on the basis of a final exam in all scholastic subjects carrying 100 marks. It is composed of an 80 marks component for annual examination and a 20 marks component for Internal Assessment (IA). IA comprises Periodic Tests (PT) with weightage of 10 marks, Notebook Submission of 5 marks and Subject Enrichment Activities of 5 marks.

    General Instructions:

    1. Out of 80 marks annual examination, 68 marks weightage shall be for theory and 12 marks weightage shall be for practical based questions.

    2. For internal assessment

    • Three periodic tests will be conducted by the school. Average of the best two tests will be calulated that will have a weightage of 10 marks towards the final result.
    • Practical / Laboratory work should be done throughout the year that will have a weightage of 5 marks towards the final result.
    • Regularity, class work and home assignment completion along with neatness and upkeep of notebook will carry a weightage of 5 marks towards the final result.
