General Instructions

  • There will be an annual examination conducted by CBSE based on the entire syllabus.
  • The annual examination will be of 80 marks and the weightage of 20 marks will be for internal assessment.
  • There shall be a periodic evaluation which shall consist of: For 5 marks- Three periodic tests conducted by the school. Average of the best two tests taken which will have a weightage of 05 marks for the final result.
  • For 5 marks – Various methods of evaluation as per the need of classroom dynamics and curricular transaction. These may include – short tests, oral tests, quizzes, concept maps, projects, posters, presentations, and inquiry-based scientific investigations, etc., and use a rubric to argue them objectively. It will also have a weightage of 05 marks for the final CBSE Board Result.
  • The practical/laboratory work should be done throughout the year and the record of the same should be maintained by the student. Practical evaluation should be continuous. Weightage will be 5
  • Points towards the final result. All practical experiments listed in the syllabus must be completed.
  • Portfolio to be prepared by the class 10 student- This will include classwork and other samples of the student’s work and will carry a weightage of 5 marks for the final results.

Important Notes for CBSE School Teacher

  • Chapter Management of Natural Resources (NCERT Chapter 16) will not be evaluated in the year-end examination. However, learners may be assigned to read this chapter and encouraged to prepare a short essay on any of the concepts in this chapter in their portfolio. This may be for internal assessment and credit may be given for periodic assessment/portfolio).
  • NCERT textbooks present information in book boxes. These help the class 10 aspirants to get conceptual clarity. However, the information in these boxes will not be evaluated in the year-end examination.
