CBSE Class 10th Board Exams 2025: What Are Common Mistakes To Be Avoided In Science Exams

Most students pay attention to theoretical concepts and forget to practice numerical problems. It is necessary to practice regularly to become proficient in applying concepts and formulas. Try to solve a minimum of five numerical problems every day to gain confidence and accuracy.

Diagrams are important in Biology, and a lack of practice can result in substantial mark penalties. Make sure you can draw and label important diagrams correctly, like the human digestive system, heart, and nephron. Repeated practice will enable you to reproduce them tidily in the exam.

In Physics, omitting units in your answers can result in mark deductions. Always include the correct units when solving numerical problems to demonstrate complete understanding.

In Chemistry, presenting unbalanced chemical equations indicates a lack of understanding. Practice balancing equations regularly to ensure accuracy during the exam.

Some students give more importance to reference books than NCERT textbooks, which are the foundation of the CBSE curriculum. Make sure to study NCERT books well, as most questions in the exam are directly taken from them.

Spending too much time on specific questions can result in incomplete papers. Practice question papers from previous years within the given time to enhance your speed and efficiency. In the exam, manage time well and skip if you're stuck, going back to difficult questions later.

Not revising can make you forget previously studied material. Plan regular revision sessions to strengthen your understanding and retention of important concepts.

Hastily reading questions will result in confusion and wrong responses. Utilize the first 15-minute reading period to thoroughly read every question, marking important words to know exactly what you are being asked before responding.

Only writing the last answer and not indicating intermediate steps can result in half or no marks. Write down every step of the calculation to show your conception of the topic and not lose marks on minute mistakes.

In drawing graphs, particularly in Physics or Chemistry, missing or incorrect labels (like axes, units, or titles) will cause marks to be lost. Label everything on your graph correctly and use a ruler for neatness.
