How to Prepare for the Class 10 Science CBSE Exam?

The CBSE board exams 2025 begin on February 15th, and it’s natural for students to feel the weight of expectations and the tension building up. One of the core subjects in CBSE class 10 is science and doing well in this paper not only boosts your CGPA but also opens doors to exciting career options like engineering, medicine, and research. 

But here’s the thing—preparing for the class 10 science CBSE exam can feel like walking a tightrope. Some students take it too lightly, thinking they can manage it all in the last few weeks. Others overdo it, drowning themselves in endless books and notes without a proper plan. Both approaches can lead to stress and confusion.

The key to success lies in striking the right balance. With a smart study plan for class 10 science and the right techniques, you can not only cover the syllabus but also ace the exam with confidence.

Importance of Science in Overall CBSE Class 10 Results

If you are planning to take the science stream in class 11, getting a 90+ in class 10 is essential for you. However, students assume that getting a good score students is all about mugging up formulas and definitions, but that is not true. The key lies in truly understanding concepts—this is where your performance shines.

What makes science special is how it supports other subjects too. For instance, practising physics numericals can sharpen your problem-solving skills for maths. Similarly, crafting detailed answers in biology can improve how you approach descriptive questions in social studies.

So, don’t see science as an intimidating challenge. Instead, treat it as a stepping stone to not just acing your exams, but also building skills for the future.

Understanding the Science Paper Structure

Before you dive into the “How to prepare for class 10 science CBSE exam” section, it is crucial to know what the science exam looks like. Here is the breakdown:

Section A: Physics

1. Review past year’s papers to analyse which chapters focus on what types of questions. Some have more diagrams and sums than theory questions.
2. Practise numerical questions, units, and conversions regularly and revise formulas and their derivations frequently.
3. Understand the application of concepts through diagrams and labelling.
4. Solve problems step by step to avoid calculation errors. Check them in the same way to avoid silly mistakes.
5. Allocate time separately for both theoretical and problem-solving practice.

Section B: Chemistry

1. Prioritise key topics like chemical reactions, acids and bases, and carbon compounds.
2. Memorise important chemical equations and reaction mechanisms.
3. Use the periodic table as a reference to understand trends and properties.
4. Practise writing balanced equations and identify common errors.
5. Perform small experiments (under guidance) to grasp concepts practically.

Section C: Biology

1. Emphasise chapters on life processes, reproduction, heredity and evolution.
2. Learn and understand diagrams like the digestive system, heart, and reproductive organs by heart.
3. Practise labelling diagrams neatly and correctly.
4. Write answers with biological terms and keywords to score well.
5. Focus on the “why” behind processes to clarify doubts.

How to Prepare for Class 10 Science CBSE Exam?

Preparing for the class 10 science CBSE exam requires focus, strategy, and consistent practice. These class 10 science preparation tips will guide you further:

1. Focus on the Syllabus

Your CBSE class 10 syllabus is your ultimate guidebook. Highlight the topics and subtopics mentioned in the syllabus, and start from there. For example, if ‘Carbon and Its Compounds’ is listed, ensure you’ve covered everything from the types of bonds to common reactions. Stick to what is prescribed—don’t go on a wild goose chase into unnecessary details.

2. Master NCERT Textbooks

The NCERT textbook is your best friend for the Science exam. CBSE loves setting exam questions straight from NCERT exercises and it is considered one of the best books for class 10 science exams. Pay attention to the in-text questions, activities, and solved examples.

For additional clarity, Oswal Publishers’ question banks can supplement your learning by providing chapter-specific summaries and extra practice questions.

3. Utilise Question Banks, Sample and Previous Year Papers

Solving sample papers and previous year’s question papers is like a dress rehearsal before the big day. It gives you a feel of the actual exam pattern and helps you identify which topics need more attention.

For instance, while practising Oswal Publishers’s sample papers, you might discover that ‘Magnetic Effects of Current’ often has tricky application-based questions. Solving these builds your confidence and speeds up your problem-solving skills.

4. Consistent Practice

Science isn’t a subject you can cram overnight. Consistency is the secret sauce. Set aside at least 1-2 hours daily for science. Alternate between sections—physics one day, chemistry the next, and then biology.

Create a dedicated notebook for formulas, definitions, and important diagrams. Keep revisiting these during your free time. It’s like feeding your brain small bites of science every day instead of a heavy meal in one go.

5. Class 10 Science Exam Time Management

Time management can make or break your exam. Here’s a trick: allocate 45 minutes for each section during the exam. Start with your strongest section—if biology is your forte, tackle it first to build confidence.

Read the questions carefully and don’t spend too much time on a single question. Attempt the easier ones first and come back to the tough ones later. Practising mock tests with a timer can prepare you for this.

Important Topics for Scoring High in Science Exam

Science is divided into five units, each carrying a specific weight. Here is a breakdown of the important topics for the class 10 science exam:

This table shows how marks are distributed across different topics. For example, units I and II (chemistry and biology) together hold the most weightage, making them essential for your preparation. Physics topics in units III and IV require consistent practice to secure marks. Internal assessment adds 20 marks, so don’t overlook assignments, practicals, and projects—they can boost your score significantly. Create your science exam strategy for class 10 based on these criteria.

Conclusion

Preparing for the class 10 science CBSE exam is not rocket science—it is about working smartly. Focus on understanding the syllabus, having NCERT at your fingertips, and practising consistently. Science can boost your CGPA and overall results if you tackle it strategically.

Remember, with resources like Oswal Publishers’ question banks and sample papers, you have tools to simplify your journey. So, put on your lab coat, grab your periodic table, and start studying like a pro!
