How to Score 95+ Marks in CBSE Class 12 Physics

Introduction

NEET preparation revolves around three subjects:

Scoring 95+ marks in Physics may look difficult to many students. But honestly, it is not an unrealistic target. As a Physics teacher, I have seen many students who are capable of scoring very well but lose marks because of a few common mistakes.

They memorise formulas without understanding them. They start solving sample papers too late. They don't practise derivations properly. They ignore diagrams. They know the answer but don't present it properly. They spend too much time on difficult questions and lose easy marks. And most importantly, they don't analyse their mistakes.

So, if you are a Class 12 CBSE student targeting 95+ in Physics, remember this:

Let's understand how you can actually achieve this target.

1. First Understand What “95+” Actually Means

Don't simply say, “Mujhe Physics mein 95+ chahiye.” Break your target into smaller parts.

For the current CBSE Class 12 Physics structure, the theory component is 70 marks and the practical/internal component is 30 marks.

This makes the target much more realistic. You don't need to get every question correct. You need to minimise avoidable mistakes.

2. Don't Start With Sample Papers

This is one of the biggest mistakes students make. A student completes two or three chapters and immediately starts solving full-length sample papers

Of course it is. A sample paper is designed to test your preparation. It is not designed to teach you the chapter. Your preparation should happen in this order:

Don't reverse this order.

3. Build Your Physics Preparation Around Three Pillars

Pillar 1: Conceptual Understanding

You should know:

• What the physical quantity means
• Which law is being used
• Why a formula works
• When a formula can be applied
• What assumptions are involved

Pillar 2: Question Practice

You should practise:

• Numerical problems
• Conceptual questions
• Assertion-type questions
• Case-based questions
• Graph-based questions
• Previous-year questions

Pillar 3: Answer Presentation

This is where many otherwise good students lose marks. Knowing the answer and writing the answer in a way that earns marks are two different skills.

4. How I Recommend Studying Every Physics Chapter

Don't randomly jump between theory and questions. Use a fixed chapter cycle.

Step 1: Understand the Concept

First understand the chapter from your teacher, class notes and NCERT. Don't worry about solving 100 questions immediately. Ask yourself: “What is actually happening physically?” Once you understand the physical meaning, formulas become much easier to remember and apply.

Step 2: Make a Formula Sheet

Keep your formulas short and organised. For example, in Current Electricity, your formula sheet may include Ohm's law, resistivity, series and parallel combinations, Kirchhoff's rules, Wheatstone bridge, meter bridge and electrical power. But don't just write formulas. Also write where they are applicable.

Step 3: Prepare Important Derivations

For CBSE Physics, derivations should not be treated as optional. Maintain a separate list of important derivations. For every derivation, know the diagram, given condition, principle or law used, mathematical steps and final result. Don't memorise the derivation word-for-word. Understand the flow.

Step 4: Solve Basic Questions

Start with simple applications. This builds confidence and helps you understand how the formula is actually used.

Step 5: Solve Board-Level Questions

Once your basics are clear, start solving questions at the level expected in the CBSE examination.

Step 6: Solve PYQs

Previous-year questions are extremely useful because they show you how concepts are actually tested.

Step 7: Maintain a Mistake Notebook

Write down formula mistakes, conceptual mistakes, calculation mistakes, unit/sign mistakes and questions you guessed incorrectly. This notebook becomes extremely valuable during revision.

5. Diagrams Can Help You Score Better

This is something I repeatedly tell my students. In Physics, a good diagram is not decoration. It communicates your understanding.

Diagrams are particularly useful in topics involving:

• Ray Optics
• Electric Fields
• Capacitors
• Moving Charges
• Electromagnetic Induction
• AC Circuits
• Semiconductor Devices

Practise drawing important diagrams before the examination. Don't wait until the board exam to draw them for the first time.

Make sure your diagrams are:

• Neat
• Properly labelled
• Relevant to the question
• Large enough to understand

6. The Most Important Rule for Numericals

When solving a numerical, don't jump directly to the final answer. Use a proper structure

• Given: Write the known quantities.
• Formula: Write the relevant equation.
• Substitution: Put the values into the formula.
• Calculation: Show the important steps.
• Final Answer: Write the answer with the correct unit.

7. Don't Ignore Units

This sounds very basic, but I have seen students lose marks because they forget unit conversion, write incorrect units, confuse prefixes, use centimetres instead of metres, or forget powers of ten.

Before submitting a numerical, ask yourself:

That small check can save marks.

8. NCERT Is Important for CBSE Physics

For CBSE preparation, don't treat NCERT as something you read only once. Use it repeatedly.

Pay attention to:

• Definitions
• Laws
• Diagrams
• Graphs
• Examples
• Important statements
• Applications
• Formula relationships

Don't underline the entire chapter. If everything is important, nothing is important.

9. PYQs Are Your Best Reality Check

Once a chapter is prepared, solve previous-year questions.

Why? Because PYQs tell you: “What kind of thinking does CBSE expect from me?”

You will start recognising recurring concepts and question styles.

After every wrong question, ask:

• Was it a concept mistake?
• Was it a formula mistake?
• Was it a calculation mistake?
• Was it a question-reading mistake?
• Was it a unit mistake?
• Was it a memory mistake?

Maintain a Physics Mistake Notebook.

10. Don't Study Every Chapter in Exactly the Same Way

Your preparation should be systematic, but your revision time should be intelligent.

The current CBSE syllabus covers major areas such as Electrostatics, Current Electricity, Magnetic Effects of Current and Magnetism, Electromagnetic Induction and Alternating Current, Electromagnetic Waves, Optics, Dual Nature of Radiation and Matter, Atoms and Nuclei, and Electronic Devices.

Don't assume that a particular chapter is guaranteed to carry a specific number of marks. Instead, use the official syllabus, sample papers and previous-year questions to understand the examination requirements.

Your goal should be complete syllabus coverage with extra attention to your weak areas.

11. Don't Ignore Your Practical Marks

If your target is 95+, your practical marks matter.

Prepare properly for:

• Experiments
• Viva
• Practical file
• Activities
• Graphs
• Sources of error
• Precautions
• Formulae used in experiments

If you can secure around 28–30 out of 30 in practicals, your pressure on the theory paper becomes much lower.

12. How to Revise Physics Before the Board Exam

Don't revise the entire syllabus in exactly the same way. I recommend three levels of revision.

Revision 1: Concept Revision

• Theory
• Concepts
• Formulae
• Derivations
• Diagrams

Revision 2: Question Revision

• PYQs
• Important numericals
• Conceptual questions
• Case-based questions

Revision 3: Exam Revision

• Formula sheets
• Derivation list
• Mistake notebook
• Important diagrams
• Frequently confused concepts

At this stage, don't start learning five new books.

13. A Practical 30-Day Strategy

If your syllabus is already complete, you can use the following approach.

Days 1–15

Chapter-wise revision + PYQs. Focus on understanding weak chapters and solving questions.

Days 16–22

Mixed chapter practice. Stop solving questions chapter-by-chapter only. Mix different chapters.

Days 23–27

Full-length papers. Attempt papers under proper examination conditions. No phone. No unnecessary breaks. Follow the actual time limit.

Days 28–30

Mistake-based revision. Don't revise everything equally. Revise what you are repeatedly getting wrong.

14. How to Attempt the Physics Board Paper

Your preparation doesn't end when you enter the examination hall. Your paper-attempt strategy also matters.

Read the Paper Carefully

Use the initial reading time properly. Don't panic if you see one difficult question. There will be questions you can attempt confidently.

Attempt Easy Questions First

If the paper allows flexibility, don't waste excessive time on one difficult numerical at the beginning. Build momentum.

For Numericals

Use: Given → Formula → Substitution → Calculation → Final Answer + Unit.

For Derivations

Use: Diagram → Principle → Mathematical Steps → Final Result.

For Theory Questions

Don't write unnecessary stories. Use: Definition → Explanation → Formula/Equation → Diagram/Example where required.

15. One Habit That Can Take You From 85 to 95+

This is probably the most important advice in this entire article.

Suppose you score 56/70. Don't just say: “56 aa gaye.” Find out where the remaining marks went.

For example:

• 4 marks lost due to concepts
• 3 marks due to calculations
• 2 marks due to incomplete answers
• 2 marks due to careless mistakes
• 3 marks due to time management

Now you know exactly what needs to be fixed.

Your next target isn't simply: “Score 65.” It is: “Recover those 14 marks.”

That is how improvement becomes measurable.

16. What NOT to Do If You Want 95+

Don't change teachers repeatedly: Every teacher has a different explanation style. Constantly switching teachers can create confusion.

Don't collect ten reference books: Complete your primary study material first.

Don't memorise formulas blindly: Understand their application.

Don't leave derivations until the last week: They need repeated practice.

Don't ignore practicals: Those marks matter.

Don't solve papers without analysing them: The analysis is where much of the learning happens.

Don't study only the chapters you like: Your weak chapters are often where your marks are being lost.

17. A Practical Daily Routine for Physics

If you are preparing alongside other subjects, even 2–3 focused hours of Physics can be productive.

You don't have to follow these exact timings. The important thing is to maintain regular contact with Physics.
