Aug 14, 2017 11:08 IST

class 10 science syllabus, cbse science syllabus, cbse class 10 syllabus 2017-2018CBSE has released the Class 10 Science syllabus for the academic session 2017-2018. In this article you will get the complete syllabus of CBSE Class 10 Science.

This year as per the CBSE’s remodeled assessment structure which has made the CBSE Class 10 Board exams mandatory, the assessment scheme will have an 80 marks component for class 10 Board examination in all scholastic subjects along with a 20 marks component of Internal Assessment (IA).

Class 10th Science NCERT Book

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.

4. 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.
