Total--- 70 marks

3. Weightage to form of Questions
S.N Form of Questions Marks for each questions No of questions Total marks
1 Long Answer Type (LA) 3 5 15
2 Short Answer Type (SA) 2 19 38
3 Very Short Answer Type (VSA-I)
(MCQ) 1 7 7
4 Very Short Answer Type (VSA-II) 1 10 10
TOTAL 70

Note : Although the weightage to different chapters and forms of questions has been assigned, the paper setters will adhere to the weightage but there can be a slight variation in the distribution of marks over types of question.

The expected time required for attempting the different forms of questions is as follows:
S. N. Form of Question Expected time for each
1 Long Answer Type (LA) 10 min
2 Short Answer Type (SA) 5 min
3 Very Short Answer Type (VSA- I & II) 11/2 min

As the total time is calculated on the basis of the number of questions required to be answered and the length of their anticipated answers, it would therefore, be advisable for the candidates to budget their time properly by cutting out the superfluous words and be within the expected time limits.

4. Scheme of Options
(There will be no overall choice. However, there is an internal choice in two questions of 2 marks category and one question of 3 marks category.)

5. Weightage to Difficulty level of Questions.
S. N. Estimated Difficulty Level Percentage
1 Easy 20
2 Average 60
3 Difficult 20

A question may vary in difficulty level from individual to individual. As such, the assessment in respect to each question will be made by the paper setter on the basis of general anticipation from a group as a whole taking the examination. This provision is only to make the paper balanced in weightage, rather than to determine the pattern of marking at any stage.
