What are Sets in CBSE Class 12?
In CBSE Class 12 board examination, sets are slightly different versions of the same question paper made for a subject.
The questions can be phrased in a varying order and can be slightly altered. However, all sets of questions are guided by the same syllabus and marking scheme.
All sets focus on the same concepts to be tested and have the same amount of marks.
The primary reason is to ensure equality, minimize the possibility of cheating, and avoid leaking of papers.
How Many Sets are There in CBSE Class 12? ( 2025-26 Updated)
The 2025-26 academic session (generally) presupposes that CBSE has several sets for each major subject. It is crucial to note that there are many major and minor subjects in CBSE class 12 that constitute the overall result of students.
Students in most Class 12 subjects usually have 5 major sets. They are commonly referred to as Set 1, Set 2, Set 3, etc. which have entirely different questions.
These sets can be classified depending on the subject and the students who have to give the exams in different parts of India and outside India.
Difference Between Major Sets and Subsets in CBSE Class 12
Major sets are the main versions of the question paper that are prepared by CBSE.
These sets might include questions in various orders or minor internal changes that cover the same subject syllabus.
For example, if there is an exam of maths or physics, the numbers would be changed in the questions so that students cannot copy answers directly from their peers – and note that calculators are not allowed in CBSE Class 12 for most such subjects.
The main set is changed in minor ways into subsets which may be classified by different code numbers.
The questions of these subsets are just shuffled to ensure there are the least chances of cheating in the exams.
Nevertheless, the level of difficulty, syllabus covered, and marking scheme are overall identical in these sets.
Why Does CBSE Use Multiple Sets in Class 12 Board Exams?
CBSE uses multiple sets in Class 12 boards exams due to the following reasons:
1. Prevention of Malpractice and Cheating
As the number of students in the same examination center is in the hundreds, distribution of various sets helps in minimizing chances of copying answers.
Due to multiple sets the question number and order would be different even if two students attempt to copy answers.
2. Avoiding Paper Leaks
Various sets are used to reduce the effects of any possible paper leak.
In case any of the sets is compromised the other sets remain safe, thus maintaining the integrity of the examination system.
3. Fairness and Equal Opportunity
The sets are formed on the basis of the same blueprint and rules.
This makes sure that no student is benefited or disadvantaged because of the set they are given.
4. Managing the Large Number of Students
CBSE takes exams of lakhs of students in India and foreign schools with CBSE affiliation.
Several variations of sets contribute to the effective management of logistics and smooth distribution of papers.
5. Testing the Same Concepts in Different Ways
The sets can test the same concept using a few variations of questions.
This would ensure that learning is evaluated adequately and students utilize good critical thinking skills to approach varied questions.
How Are CBSE Class 12 Question Paper Sets Distributed?
Question papers are randomly distributed to the students in the examination hall on the examination day.
Invigilators make sure that different sets are given to different students.
The first page of the question paper has the set number and series code printed on it.
To avoid errors in the evaluation, it is necessary that correct set codes are written on the answer sheets by the students.
The distribution is done in a manner that ensures fairness and transparency during the examination process.
Do Different Sets Have Different Difficulty Levels?
CBSE makes sure that all sets are of equal difficulty. Each set includes multiple sections that contain the same number of easy, moderate, and difficult types of questions, and the CBSE grading system ensures fair evaluation across all sets.
However, students sometimes think that one of the sets was more difficult than another.
In exams, evaluation is done moderately by CBSE educators so that overall results remain fair for all students.
