Introduction
If you just walked out of the Physics exam hall — or you’re preparing for 2026 — this article is exactly where you need to be. The CBSE Class 12 Physics Question Paper 2025 was held on February 21, 2025, and students across India had a lot to say about it. Some found it fair. Some found the numericals sneaky. And a few probably wished Newton had never discovered gravity.
Let’s break it all down — the paper structure, section-wise analysis, important chapters, difficulty level, and how you can use this paper smartly for your 2026 preparation.
What Was the CBSE Class 12 Physics Exam 2025 Like?
The Central Board of Secondary Education (CBSE) conducted the Class 12 Physics Board Exam 2025 on February 21, 2025. The paper carried a total of 70 marks for theory, with students getting 15 minutes of reading time before the 3-hour exam began.
The practical component carried 30 marks, making the total score out of 100 marks — the standard CBSE pattern.
Around 30% of the questions were competency-based, focusing on application and analytical skills. This shift toward application-based thinking is something CBSE has been pushing consistently in recent years.
CBSE Class 12 Physics 2025 – Paper Structure at a Glance
The question paper contained 33 compulsory questions, divided into five sections — A, B, C, D, and E. No overall choice was given, but internal choices were available in select questions.
Here is a clear breakdown of the paper structure:
| Section | Question Numbers | Type of Questions | Marks per Question | Total Marks |
|---|---|---|---|---|
| A | 1 to 16 | MCQ + Assertion-Reason | 1 mark each | 16 marks |
| B | 17 to 21 | Very Short Answer (VSA) | 2 marks each | 10 marks |
| C | 22 to 28 | Short Answer (SA) | 3 marks each | 21 marks |
| D | 29 & 30 | Case Study-Based | 4 marks each | 8 marks |
| E | 31 to 33 | Long Answer (LA) | 5 marks each | 15 marks |
| Total | 33 Questions | — | — | 70 Marks |
Section A contained 16 MCQs, Section B had 5 questions of two marks each, Section C had 7 questions of three marks each, Section D had two case-study questions of four marks each, and Section E contained 3 long questions of five marks each.
Chapter-Wise Weightage in CBSE Physics 2025
Not all chapters are created equal. CBSE has a clear pattern when it comes to which topics get the most marks. Based on the 2025 paper:
High-weightage units in the 2025 Class 12 Physics exam included Electrostatics, Current Electricity, Magnetism, Optics, and Modern Physics. Electrostatics and Electromagnetic Waves were among the highest scoring units.
| Unit | Key Topics | Approx. Marks |
|---|---|---|
| Electrostatics | Coulomb’s Law, Capacitors, Gauss’s Law | 8–10 marks |
| Current Electricity | Ohm’s Law, Kirchhoff’s Laws, Wheatstone Bridge | 7–8 marks |
| Magnetic Effects & EMI | Faraday’s Law, AC Circuits | 8–10 marks |
| Optics | Ray Optics, Wave Optics, Interference | 10–12 marks |
| Modern Physics | Photoelectric Effect, Nuclei, Semiconductors | 10–12 marks |
| Communication Systems | Modulation, Bandwidth | 3–4 marks |
Difficulty Level – Was the 2025 Paper Easy or Tough?
The CBSE board Class 12 Physics 2025 paper followed the expected blueprint. Students noticed repeated concepts from chapters like Electrostatics, Current Electricity, Optics, Electromagnetic Induction, and Modern Physics.
Overall, most students and educators rated the paper as moderate. The MCQ section was straightforward for well-prepared students. The case-study questions required real-life application of concepts — which is where many students lost marks by not reading carefully.
The long-answer questions (Section E) included derivations and numericals. Anyone who had revised NCERT examples thoroughly found these manageable.
Key Physical Constants Provided in the Paper
Students could use the following physical constants wherever necessary:
- Mass of electron (mₑ) = 9.1 × 10⁻³¹ kg
- Mass of neutron = 1.675 × 10⁻²⁷ kg
- Mass of proton = 1.673 × 10⁻²⁷ kg
Calculators were NOT allowed in the exam.
This is a good reminder — if you’re preparing for 2026, practice your calculations by hand. Relying on a calculator during revision is a trap many students fall into.

How to Use the 2025 Paper for CBSE 2026 Preparation
This is where things get practical. The 2025 paper is not just a historical document — it is a blueprint.
CBSE rarely asks out-of-syllabus questions, so smart revision matters more than studying new material at the last moment. Students who practice real board papers usually score higher because they become familiar with the type of numericals, derivations, and theory questions asked by CBSE.
Here is a simple strategy to use the 2025 paper effectively:
Step 1 – Solve it under timed conditions. Give yourself exactly 3 hours. No peeking at solutions. This builds exam stamina and reveals your actual weak spots.
Step 2 – Analyse your mistakes. Did you drop marks in MCQs? Numericals? Derivations? Each category has a different fix.
Step 3 – Map mistakes to NCERT chapters. Every wrong answer points to a chapter that needs revision. Trust the process.
Step 4 – Practice internal choices. Section E gives you a choice. Most students pick randomly. Practice both options so you can make an informed decision on exam day.
If you focus on NCERT examples, all derivations, important numericals, and 5–6 previous year papers, scoring above 60 out of 70 in Physics becomes very realistic.
Important Tips for CBSE Class 12 Physics Board Exam
- Diagrams matter. Ray diagrams in Optics and circuit diagrams in Current Electricity can earn you full marks only if drawn clearly with labels.
- Show every step in numericals. Even if your final answer is wrong, step-wise marks are awarded.
- Read case studies twice. The data in case-study questions is easy to misread under exam pressure.
- Attempt questions you know first. You can attempt questions in any sequence in the CBSE board exam. Attempting questions you know well first helps you build confidence and manage time better.
- Units and significant figures. Write the unit after every numerical answer. Forgetting units is one of the most common and unnecessary mark losses.
CBSE Class 12 Physics 2025 vs 2024 – What Changed?
