By Sandhya Classes, Zirakpur – Trusted Science Coaching for Class 10

Class 10 board exams are crucial. Science requires strategy across Chemistry, Physics, and Biology. Many students make simple but costly errors. Let’s fix that!

Here are 7 science exam blunders to avoid:

1. Not Following CBSE Answer Format
Mistake: Writing without structure.
Fix: Practice writing answers for 2, 3, and 5 marks in the proper format.

2. Skipping Chemical Reactions
Mistake: Not learning chemical equations.
Fix: Memorize and practice all important chemical reactions and balance them.

3. Leaving Out Physics Numericals
Mistake: Avoiding numericals or guessing.
Fix: Practice step-wise: formula → substitution → final answer (with units).

4. Ignoring Diagrams in Biology
Mistake: Writing theory only.
Fix: Draw neat diagrams. Even a labeled sketch can get full marks.

5. Studying One Subject Too Much
Mistake: Focusing only on Chemistry or Bio.
Fix: Allocate time equally to Physics, Chemistry, and Biology.

6. Attempting All Internal Choices
Mistake: Solving more than required.
Fix: Attempt only one out of the two internal choices per question.

7. Not Solving Sample Papers
Mistake: No exam practice.
Fix: Solve full papers under timed conditions every week.

“Exam success = Smart planning + Balanced revision + Practice papers. Nothing else.”
