Tips to Score High in Class 10 Science Pre-Boards

Scoring high in Class 10 Science pre-boards is very important because it helps students get ready for the final CBSE Class 10 2026 board exam. Here are some simple and practical tips to help students score high in Science pre-boards:-

1. Complete All NCERT Chapters

Before solving any CBSE Class 10 pre board sample paper, it is very important to complete all NCERT chapters properly. Most questions in the pre-boards and boards come directly from the NCERT content.

• Students can start with chapters in Physics, like Motion, Light, Electricity, Work & Energy, and Magnetic Effects of Current.

• In Chemistry, students should focus on Chemical Reactions & Equations, Acids & Bases, Metals & Non-metals, Carbon Compounds, and Periodic Table.

• In Biology, students should cover Life Processes, Control & Coordination, Reproduction, Heredity & Evolution, and Human Body Systems.

2. Make Your Own Notes

Making personal notes while studying each chapter will help students revise quickly and understand concepts better.

Students can write short points for each topic, for example, formulas in Physics, chemical reactions in Chemistry, and diagrams in Biology.

Notes should include important definitions, steps to solve problems, and diagrams for easy visual memory.

Students should also note common mistakes to avoid while solving questions from the CBSE Class 10 pre board sample paper.

These notes should help students practise multiple CBSE pre board question papers class 10 without constantly referring to the NCERT books.

3. Practise Regularly with Sample Papers

Once chapters are complete and notes are ready, students can start practising pre board CBSE class 10 science sample paper. This step helps them understand the exam pattern and types of questions.

• Students can solve CBSE Class 10 pre mid term sample papers for practice before attempting full-length papers.

• They can attempt CBSE pre board question papers class 10 under exam-like conditions with a timer.

• Students should practise different types of questions, including multiple-choice, short answers, long answers, diagram-based questions, and numerical problems.

4. Analyse Your Performance

After solving each CBSE Class 10 pre board sample paper, students should analyse their performance carefully.

 

• Check answers with the detailed solutions provided in the sample papers.

• Note the questions they got wrong and revise the related chapters.

• They can see which chapters are giving more trouble, for example, Physics Motion or Chemistry Chemical Reactions.

5. Focus on Important Topics

Students are advised to focus more on chapters that have higher weightage in exams. The CBSE pre board question papers class 10 often show trends from previous years.

• In Physics, important topics include Light, Electricity, Magnetic Effects of Current, Work & Energy, and Sound.

• In Chemistry, focus should be on Chemical Reactions, Acids & Bases, Metals & Non-metals, and Carbon Compounds.

• In Biology, students should revise Life Processes, Control & Coordination, Reproduction, Heredity & Evolution, and Human Body Systems.

• Using pre board question paper class 10 science from PW helps identify these high-weightage chapters.

7. Revise Using Notes and Sample Papers

Revision is very important to keep concepts fresh in mind. Students can use both notes and pre board question paper class 10 science for revision.

• Students can solve one CBSE pre board sample paper of class 10 science per week as a full mock test.

• Revise tricky questions and difficult diagrams from previous CBSE Class 10 pre mid term sample papers.

• Notes will help quickly revise formulas, key definitions, and steps for numerical questions.

8. Practice Diagrams and Practical Skills

Science pre-boards include diagrams and practical questions. Students can practise these separately.

• Students should draw important Biology diagrams like the Human Heart, the Neuron, the reproductive system, and Photosynthesis.

• For Physics, students are advised to practise diagrams for Circuits, Lenses, and Reflection/Refraction.

• Chemistry practicals like Reactions, Titrations, and Observations can also be practised.

• Using CBSE pre board question papers class 10 science helps students know which practicals are asked frequently.
