Computer Science (Theory) - Class XII

Subject Code: 083

Design of Question Paper for the Examination

Time: 3 hours                                                                                                      Max. Marks: 70

Weightage of marks over different dimensions of the question paper shall be as follows:

A.           Weightage to different topics/content units

S.No	Topics	Marks
1	Review of C++ covered in Class XI	12
2	Object Oriented Programming in C++	12
3	Data Structure & Pointers	14
4	Data File Handling in C++	06
5	Databases and SQL	08
6	Boolean Algebra	08
7	Communication and Open Source Concepts	10
	Total	70

B.            Weightage to different forms of questions

S.No	Forms of Questions	Marks for each	No. of	Total
		question	Questions	Marks
1	Very Short Answer questions (VSA)	01	09	09
2	Short answer questions – Type I (SA I)	02	13	26
3	Short answer questions – Type II (SA II)	03	05	15
4	Long answer questions (LA)	04	05	20
		Total	32	70

C.           Scheme of Options

There will be no overall choice. All questions are compulsory.

D.           Difficulty level of questions

·                     Based on the above design, two sets of sample papers along with their blue prints and Marking schemes have been included in this document.

·                     About 20% weightage has been assigned to questions testing higher order thinking (HOT) skills of learners.
