CBSE Class 10 Science Exam Tips: Avoid These Common Mistakes

The CBSE Class 10 board exams are starting from February 15, 2025. Science is a crucial subject, and students often make some common mistakes while attempting the exam. Here are essential tips to help students avoid these errors and score well.

1. Avoid Rushing Through MCQs

One of the most common mistakes students make in Multiple Choice Questions (MCQs) is selecting an option too quickly without fully understanding the question.

• Read the question carefully before looking at the options.
• Try to think of the answer before checking the choices.
• Ensure you write the MCQ answer in the correct format: "Answer 2. (a) Answer".

2. Writing Chemical Reactions Properly

Science includes many chemical reactions, and students must be careful while writing them.

• Even if a reaction is not explicitly asked, writing it can add clarity.
• Include the physical states of reactants and products in brackets (e.g., H₂(g), H₂O(l)).
• Ensure the reaction is properly balanced.

3. Drawing Diagrams and Proper Labeling

In subjects like Biology, diagrams play a crucial role.

• Draw clear and neat diagrams using a pencil.
• Label all parts correctly and write labels on the right side of the diagram.

4. Physics Ray Diagrams

For Physics, students must be careful while drawing Ray Diagrams.

• Draw straight rays using a ruler and compass.
• Include arrowheads to indicate the direction of light rays.
• Always label objects and images correctly (e.g., AB and A’B’).

5. Solving Numerical Problems

Numerical problems are essential, especially in topics like Light, Electricity, and Magnetism.

• Write down the given data before solving.
• Mention the correct formula before substituting values.
• Always include the correct units in your final answer.
• Highlight the final answer by underlining or boxing it.

Final Tip

Before submitting your paper, double-check your answers to ensure accuracy. These small steps can make a big difference in scoring higher marks in the CBSE Class 10 Science exam.

Good luck with your exams!
