The theory paper is conducted for a total of 70 marks, where Electrochemistry carries the highest weightage of 9 marks. Most of the Chemistry questions are directly based on NCERT textbooks. An analysis of previous years' papers shows that similar types of questions are common in this subject. For example, in 2023, a question from the chapter Chemical Kinetics was framed as follows:

A similar question, but with a slight twist, was asked in the 2023 Compartment Set-1 Chemistry paper:

Q: A reaction follows second order kinetics. How is the rate of reaction affected if the concentration of the reactant is reduced to half? Choose the correct value from the following:

(a) four times

(b) eight times

(C) 4/1 of the original value

(d) three times

In the most repeated questions CBSE Class 12 PDF for Chemistry, you will find similar question formats. Practising such questions will certainly give you insight into how exam questions are framed and which concepts are most commonly tested across chapters.

CBSE Class 12 Biology Most Repeated Questions

Among the five units in CBSE Class 12 Biology, Genetics and Evolution is the highest weightage unit, carrying 20 marks. Topics like Molecular Basis of Inheritance, Sexual Reproduction in Flowering Plants, Biotechnology: Principles and Processes, Human Reproduction, Principles of Inheritance and Variation, and Ecology are the most repeated ones. It is unlikely to find exact word-for-word questions repeated, but the underlying concepts remain the same. 

To help you understand what the most repeated questions look like in this subject, here is an original example of two questions from different Biology papers that are very similar, yet distinct:

Question 1:

(i) Draw a labelled diagram of a cross-section of a human seminiferous tubule (label any four parts).

(ii) Explain the hormonal regulation of spermatogenesis.

These questions were asked in the 2024 Biology Compartment Set-1 paper.

A similar question with a slight twist was asked in the Biology 2025 Compartment Set-1 paper:

Question 2: 

(i) Where does spermatogenesis occur in human testes? Describe the process of spermatogenesis up to the formation of spermatozoa.

(ii) Trace the path of movement of spermatozoa from the testes up to the ejaculatory duct.

How to Find Most Repeated Questions for CBSE Class 12

If you want to discover more questions beyond our Class 12th CBSE most repeated questions PDF, I have a simple 4-step formula for you.

Follow these steps:

Step 1: Collect 5–10 years of CBSE Class 12 Question Papers

Start by collecting all types of CBSE question papers, such as sample papers, marking schemes, previous year question papers, competency-based practice questions, and question banks.

Next, create an Excel sheet and start building a dataset as you continue to analyse those papers. Your Excel sheet should have columns such as Year, Chapter, Question, Marks, and Concept.

Step 2: Group Questions in a Chapter-Wise Manner

Don’t just analyse the year-wise papers; categorise them chapter-wise. For example, for Physics, you can categorise them like this:

Electrostatics: Dipole, Capacitor, Gauss's Law.

For Chemistry questions, you can do it like this:

Coordination Compounds: Nomenclature, Isomerism, Werner's Theory.

This is an important step because exact word-by-word questions are not asked in the board exams, but the concepts are repeated. So, tracking a question like ’State Faraday’s First Law’ isn’t as helpful as tracking a broader concept like Faraday’s Law, Electromagnetic Induction, etc.

Step 3: Count Concept Frequency

It is important to track the concept frequency, so count how often each concept has appeared. A concept appearing repeatedly over many years deserves special attention.

You can count concept frequency like this:

Concept	Frequency
Cyclotron	6 years
Logic Gates	9 years

Step 4: Revise High-Frequency Concepts, Diagrams, Derivations, Reactions, and NCERT Examples First.

There is a reason why CBSE repeats a concept, so understand the why. These could be some of the reasons for a concept to be repeated:

• Core NCERT concept

• Important real-world application

• Foundational chapter concept

• Easy to test in multiple formats

• Connected to multiple learning outcomes

Following these steps will clearly help you identify the most repeated concepts in the CBSE Class 12 board exam. You can also refer to CBSE Class 12 Topper Notes to understand effective revision and answer-writing approaches.
