CBSE Class 12th Chemistry (043) Question Paper Design 2024-25

The CBSE Class 12 Chemistry question paper is weighted according to three criteria: Remembering and Understanding, Applying, and Analysing, Evaluating and Creating along with the marks and total percentage. 3 hours are allotted for the exam. The maximum possible score is 70 in theory. Check out the tabulated statistics below for a clearer understanding.

S. No.	Domains	Total Marks	Percentage
1.	Remembering and Understanding: Exhibit memory of previously learned material by recalling facts, terms, basic concepts, and answers. Demonstrate understanding of facts and ideas by organizing, comparing, translating, interpreting, giving descriptions and stating main ideas.	28	40
2.	Applying: Solve problems to new situations by applying acquired knowledge, facts, techniques and rules in a different way.	21	30
3.	Analysing, Evaluating and Creating: 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.	21	30

No chapter wise weightage. Care to be taken to cover all the chapters.
Suitable internal variations may be made for generating various templates. Choice(s)

There will be no overall choice in the question paper.
However, 33% internal choices will be given in all the sections
