Typology of Questions
|Remembering: Exhibit memory of previously learned material by recalling facts, terms, basic concepts, and answers.
Understanding: Demonstrate understanding of facts and ideas by organizing, comparing, translating, interpreting, giving descriptions, and stating main ideas
|Applying: Solve problems to new situations by applying acquired knowledge, facts, techniques and rules in a different way.||20||25|
Examine and break information into parts by identifying motives or causes. Make inferences and find evidence to support generalizations
Present and defend opinions by making judgments about information, validity of ideas, or quality of work based on a set of criteria.
Compile information together in a different way by combining elements in a new pattern or proposing alternative solutions
- No chapter wise weightage. Care to be taken to cover all the chapters
- Suitable internal variations may be made for generating various templates keeping the overall weightage to different form of questions and typology of questions same.
There will be no overall choice in the question paper. However, 33% internal choices will be given in all the sections
