CBSE Class-12 Exam 2019 : Physics

• Year : 2019
• Marking Scheme — Physics

General Instructions:

1. The marking scheme provides general guidelines to reduce subjectivity in the marking. The answers given in the marking scheme are suggested answers. The content is thus indicated. If a student has given any other answer, which is different from the one given in the marking scheme, but conveys the meaning correctly, such answers should be given full weightage. 

2. In value-based questions, any other individual response with suitable justification should also be accepted even if there is no reference to the text.

3. Evaluation is to be done as per instructions provided in the marking scheme. It should not be done according to one's own interpretation or any other consideration. Marking scheme should be adhered to and religiously followed.

4. If a question has parts, please award in the right-hand side for each part. Marks awarded for different part of the question should then be totaled up and written in the left-hand margin and circled.

5. If a question does not have any parts, marks are to be awarded in the left-hand margin only. 

6. If a candidate has attempted an extra question, marks obtained in the question attempted first should be retained and the other answer should be scored out.

7. No marks are to be deducted for the cumulative effect of an error. The student should be penalized only once. 

8. Deduct ½ mark for writing wrong units, missing units, in the final answer to numerical problems.

9. Formula can be taken as implied from the calculations even if not explicitly written.

10. In short answer type question, asking for two features / characteristics / properties if a candidate writes three features, characteristics / properties or more, only the correct two should be evaluated.

11. Full marks should be awarded to a candidate if his / her answer in a numerical problem is close to the value given in the scheme.

12. In compliance to the judgement of the Hon’ble Supreme Court of India, Board has decided to provide photocopy of the answer book(s) to the candidates who will apply for it along with the requisite fee. Therefore, it is all the more important that the evaluation is done strictly as per the value points given in the marking scheme so that the Board could be in a position to defend the evaluation at any forum.

13. The Examiner shall also have to certify in the answer book that they have evaluated the answer book strictly in accordance with the value points given in the marking scheme and correct set of question paper.

14. Every Examiner shall also ensure that all the answers are evaluated, marks carried over to the title paper, correctly totaled and written in figures and words.

15. In the past it has been observed that the following are the common types of errors committed by the Examiners

• Leaving answer or part thereof unassessed in an answer script.
• Giving more marks for an answer than assigned to it or deviation from the marking scheme.
• Wrong transference of marks from the inside pages of the answer book to the title page.
• Wrong question wise totaling on the title page.
• Wrong totaling of marks of the two columns on the title page.
• Wrong grand total.
• Marks in words and figures not tallying.
• Wrong transference to marks from the answer book to award list.
• Answer marked as correct ( √) but marks not awarded.
• Half or part of answer marked correct ( √) and the rest as wrong (×) but no marks awarded.

16. Any unassessed portion, non-carrying over of marks to the title page or totaling error detected by the candidate shall damage the prestige of all the personnel engaged in the evaluation work as also of the Board. Hence in
order to uphold the prestige of all concerned, it is again reiterated that the instructions be followed meticulously and judiciously
