Strictly Confidential: (For Internal and Restricted use only)
Senior Secondary School Term II Examination, 2022
Marking Scheme – COMPUTER SCIENCE (SUBJECT CODE – 083)
(Series: %BAB%, SET - 4, PAPER CODE –91)
General Instructions :

1. You are aware that evaluation is the most important process in the actual and correct
assessment of the candidates. A small mistake in evaluation may lead to serious problems
which may affect the future of the candidates, education system and teaching profession. To
avoid mistakes, it is requested that before starting evaluation, you must read and
understand the spot evaluation guidelines carefully.
2. “Evaluation policy is a confidential policy as it is related to the confidentiality of the
examinations conducted, Evaluation done and several other aspects. Its’ leakage to the
public in any manner could lead to derailment of the examination system and affect the
life and future of millions of candidates. Sharing this policy/document to anyone,
publishing in any magazine and printing in News Paper/Website etc may invite action
under IPC.”
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 strictly adhered to and religiously followed. However, while evaluating answers which are
based on latest information or knowledge and/or are innovative, they may be assessed
for their correctness otherwise and marks be awarded to them. In class-XII, while
evaluating two competency based questions, please try to understand the given answer
and even if the reply is not from the marking scheme but correct competency is
enumerated by the candidate, marks should be awarded.
4. The Head-Examiner must go through the first five answer books evaluated by each evaluator
on the first day, to ensure that evaluation has been carried out as per the instructions given in
the Marking Scheme. The remaining answer books meant for evaluation shall be given only
after ensuring that there is no significant variation in the marking of individual evaluators.
5. Evaluators will mark( √ ) wherever the answer is correct. For wrong answer ‘X’ be marked.
Evaluators will not put the right kind of mark while evaluating which gives an impression that
the answer is correct and no marks are awarded. This is the most common mistake which
evaluators are committing.
6. If a question has parts, please award marks on the right-hand side for each part. Marks
awarded for different parts of the question should then be totaled up and written in the left-hand
margin and encircled. This may be followed strictly.
7. If a question does not have any parts, marks must be awarded in the left-hand margin and
encircled. This may also be followed strictly.
8. If a student has attempted an extra question, the answer of the question deserving more marks
should be retained and the other answer scored out.
9. No marks to be deducted for the cumulative effect of an error. It should be penalized only once.
10.A full scale of marks 35 (example 0-35 marks as given in Question Paper) has to be used.
Please do not hesitate to award full marks if the answer deserves it.
11.Every examiner has to necessarily do evaluation work for full working hours i.e. 8 hours every
day and evaluate 30 answer books per day in main subjects and 35 answer books per day in
other subjects (Details are given in Spot Guidelines). This is in view of the reduced syllabus
and number of questions in the question paper.

[Sub Code: 083 Series: %BAB% Paper Code: 91 Set - 4] [Page #1/15]

12.Ensure that you do not make the following common types of errors committed by the Examiner
in the past :-
● Leaving the answer or part thereof unassessed in an answer book.
● Giving more marks for an answer than assigned to it.
● Wrong totaling of marks awarded on a reply.
● Wrong transfer 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 transfer of marks from the answer book to online award list.
● Answers marked as correct, but marks not awarded. (Ensure that the right tick mark is
correctly and clearly indicated. It should merely be a line. Same is with the X for incorrect
answers.)
● Half or a part of the answer was marked correct and the rest as wrong, but no marks
awarded.
13.While evaluating the answer books if the answer is found to be totally incorrect, it should be
marked as cross (X) and awarded zero (0) Marks.
14.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.
15.The Examiners should acquaint themselves with the guidelines given in the Guidelines for spot
Evaluation before starting the actual evaluation.
16.Every Examiner shall also ensure that all the answers are evaluated, marks carried over to the
title page, correctly totaled and written in figures and words.
17.The Board permits candidates to obtain a photocopy of the Answer Book on request in an RTI
application and also separately as a part of the re-evaluation process on payment of the
processing charges.

Section -B
(Each question carries 3 marks)
8. ● Write the definition of a user defined function PushNV(N) which 3
accepts a list of strings in the parameter N and pushes all strings
which have no vowels present in it, into a list named NoVowel.
● Write a program in Python to input 5 Words and push them one by one
into a list named All.
The program should then use the function PushNV() to create a stack
of words in the list NoVowel so that it stores only those words which
do not have any vowel present in it, from the list All.
Thereafter, pop each word from the list NoVowel and display the
popped word. When the stack is empty, display the message
"EmptyStack".

For example:

If the Words accepted and pushed into the list All are
['DRY', 'LIKE', 'RHYTHM', 'WORK', 'GYM']

[Sub Code: 083 Series: %BAB% Paper Code: 91 Set - 4] [Page #8/15]

integers which are divisible by 3 or divisible by 5 from the list N into
a list named Only3_5.
● Write a program in Python to input 5 integers into a list named NUM.
The program should then use the function Push3_5() to create the
stack of the list Only3_5. Thereafter pop each integer from the list
Only3_5 and display the popped value. When the list is empty, display
the message "StackEmpty".

[Sub Code: 083 Series: %BAB% Paper Code: 91 Set - 4] [Page #9/15]

For example:
If the integers input into the list NUM are :

[10,6,14,18,30]
Then the stack Only3_5 should store

[10,6,18,30]

And the output should be displayed as

30 18 6 10 StackEmpty
Ans def Push3_5(N):
for i in N :
if i%3==0 or i%5==0 :
