CBSE Class 10 Science Board Exam 2026, scheduled for 25 February 2026, requires smart revision, especially in the last 24 hours. Instead of starting new topics, students should focus on quick revision, formulas, diagrams, definitions, important reactions, and key concepts from all three sections—Physics, Chemistry, and Biology. The final day is not for learning everything again, but for strengthening already studied chapters, improving accuracy, and boosting confidence.
During this time, revise important ray diagrams, Biology diagrams, chemical equations, and numerical formulas, and practice a few MCQs to refresh your memory. Focus on frequently asked topics and previous year questions to understand the exam pattern better. Avoid stress, manage your time wisely, and keep your study plan simple and organized.
A proper last-day strategy can help you stay calm and score better marks. Below is a complete revision plan using focused videos available on YouTube to support quick and effective preparation.

Last-Minute Preparation Strategy Class 10 Science Exam
Follow these important tips for last-minute preparation before your Class 10 Science exam:
-
Revise Important Physics Formulas: Focus on formulas from chapters like Light (Reflection & Refraction), Electricity, and Magnetic Effects of Electric Current. Understand how to apply formulas in numerical questions.
-
Practice Ray Diagrams Carefully: Revise concave and convex mirror/lens diagrams. Draw them neatly with a pencil, use a ruler, and always show arrows correctly. Proper labeling is very important.
-
Revise Important Biology Diagrams: Practice diagrams such as the Human Eye, Nephron, Digestive System, and Respiratory System. Make sure you remember all labels and functions.
-
Go Through Key Chemistry Reactions: Revise important chemical equations, types of reactions (combination, decomposition, displacement), and balancing of equations. Practice writing reactions correctly.
-
Revise Definitions and Key Terms: Go through important definitions from all chapters. Many theory questions are directly based on definitions.
-
Solve MCQs and Sample Questions: Practice objective questions to improve speed and accuracy. Focus on conceptual questions instead of memorizing answers.
-
Check Previous Year Questions (PYQs): Review commonly asked questions to understand the exam pattern and important topics.
