CBSE Class 10 Science Exam 2026, conducted by the Central Board of Secondary Education, is scheduled for Wednesday, February 25, 2026, from 10:30 AM to 1:30 PM. It evaluates their understanding of key concepts from Physics, Chemistry, and Biology while testing analytical skills, problem-solving ability, and conceptual clarity.
Science is a subject that requires regular revision, practice of numericals, and equal focus on all subjects. With proper preparation and a focused study plan, students can perform confidently and achieve high scores in this crucial exam.
Why Some Chapters Remain Underprepared?
Most students first revise the easy theory chapters. They postpone numericals, chemical reactions, and diagram-based topics. Board exams focus on application-based questions. Without regular practice, students feel confused in these sections.
Another reason is a lack of structured revision. Reading the chapter once is not enough. Science requires repeated practice. Numericals must be solved step-by-step. Chemical equations must be written again and again. Diagrams must be drawn multiple times. Without active practice, memory becomes weak.
Time management is also a problem. Students spend more time on strong chapters. Weak chapters get less attention. This creates gaps in preparation. These gaps can reduce overall marks in the final exam.
Commonly Underprepared Chapters in Physics
Physics chapters that involve formulas and calculations are often difficult for students. These include topics like:
-
Electricity
-
Magnetic Effects of Electric Current
These chapters require a clear understanding of formulas, ray diagrams, and numericals. Many students understand the theory but struggle while solving questions.
How to Fix Physics Chapters Quickly
-
First, prepare a separate formula notebook. Write all important formulas in one place. Revise them daily.
-
Second, practice numericals regularly. Solve at least 10–15 questions from each chapter. Focus on step-by-step solutions.
-
Third, revise ray diagrams carefully. Draw them neatly with proper labeling.
-
Fourth, solve previous years’ board questions. This helps in understanding question patterns and improves confidence.
Commonly Underprepared Chapters in Chemistry
In Chemistry, students often skip chapters that include reactions and trends. Important chapters include:
-
Chemical Reactions and Equations
-
Periodic Classification of Elements
-
Carbon and Its Compounds
These chapters require writing balanced equations, understanding reaction types, and learning periodic trends. Students sometimes avoid writing chemical equations repeatedly. This leads to mistakes in exams.
How to Fix Chemistry Chapters Quickly
-
Write chemical equations multiple times. Practice balancing without checking the textbook.
-
Revise reaction types such as combination, decomposition, displacement, and redox reactions.
-
Study periodic trends carefully. Understand why properties change across periods and groups.
-
For Carbon and Its Compounds, revise bonding, functional groups, and important reactions. Practice structures regularly.
Commonly Underprepared Chapters in Biology
Biology chapters often include diagrams and detailed explanations. Students may understand the concept but lose marks due to incomplete diagrams. Common weak chapters are:
-
Control and Coordination
-
How do Organisms Reproduce?
-
Heredity and Evolution
These chapters require labeled diagrams, definitions, and structured answers.
How to Fix Biology Chapters Quickly
-
Practice drawing diagrams neatly. Use pencil and proper spacing. Label all parts clearly.
-
Revise important definitions and keywords. Biology answers should include correct terms.
-
Write answers in clear steps. Use headings or points when needed.
-
Practice previous years’ diagram-based questions.
Effective Board Preparation Strategy
An effective board preparation strategy requires proper planning, regular practice, and consistent revision to score well in the exam.
-
Start preparation with the NCERT textbook and focus on clear concepts.
-
Make a daily study timetable and follow it strictly.
-
Give equal time to Physics, Chemistry, and Biology.
-
Spend extra time on weak chapters.
-
Revise formulas, reactions, and definitions regularly.
-
Practice numericals step by step for accuracy.
-
Draw important diagrams neatly and label them correctly.
-
Solve sample papers and previous year questions in a time limit.
-
Check mistakes after practice and revise weak areas again.
-
Prepare short revision notes for quick last-minute study.
-
Stay consistent, calm, and confident during preparation.
