General Instructions:

1. There will be an Annual examination based on the entire syllabus.

2. The annual examination will be of 80 marks and 20 marks shall be for Internal Assessment.

3. The components of Internal Assessment would be:

a. Periodic Assessment of 10 marks that would include:

  • For 5 marks- Three periodic tests conducted by the school. Average of the best two tests to be taken. This will have a weightage of 05 marks towards the final result.
  • For 5 marks- Diverse methods of assessment as per the need of the class dynamics and curriculum transaction. These may include- short tests, oral test, quiz, concept maps, projects, posters, presentations and enquiry based scientific investigations, etc. and use rubrics for arguing them objectively. This will also have a weightage of 05 marks towards the final result.

b. Practical / Laboratory work should be done throughout the year and the student should maintain a record of the same. Practical Assessment should be continuous. There will be a weightage of 5 marks towards the final result. All practicals listed in the syllabus must be completed.

c. Portfolio to be prepared by the student- This would include classwork, other samples of student work, self-assessment and peer-assessment. This will carry a weightage of 5 marks towards the final results.
