General Instructions

  1. Out of 80 marks annual examination, 68 marks weightage is for theory and 12 marks weightage is for practical based questions.
  2. For internal assessment:
    • Three periodic tests are conducted by the school. Average of the best two tests is calculated with a weightage of 10 marks towards the final result.
    • Practical / Laboratory work should be done throughout the year as it carries a weightage of 5 marks towards the final result.
    • Regularity, classwork and home assignment completion along with neatness and upkeep of notebook carries a weightage of 5 marks towards the final result.

Before starting with the new session, students must be well aware of the latest CBSE syllabus.Syllabus for Science, Class 10 CBSE Class 10 Notes | EduRev

Only for Internal Assessment

Note: Learners are assigned to read the below-listed part of Unit V. They can be encouraged to prepare a brief write up on anyone concept of this Unit in their Portfolio. This may be an assessment for Internal Assessment and credit may be given (Periodic assessment/Portfolio). This portion of the Unit is not to be assessed in the year-end examination.
