8-Hour Revision Strategy & Preparation Tips
To make the most of your time before the 25 February exam, follow this structured schedule:
-
Hour 1-2 (Chemistry Basics): Focus on balancing chemical equations and memorizing the reactivity series.
-
Hour 3-5 (Physics Numericals): Master the sign convention for mirrors/lenses and practice calculating equivalent resistance in parallel and series circuits.
-
Hour 6-7 (Biology Diagrams & Definitions): Label the human heart, brain, and excretory system. Revise definitions for terms like "Transpiration" and "Tropic Movements."
-
Hour 8 (Final Formula Check): Do a quick run-through of all Physics formulas (P=VI, V=IR, 1/f=1/v-1/u) and Chemistry functional groups.
Last-Minute Preparation Guidelines:
As you approach the final hours before the class 10th Science board exam, your strategy should shift from learning new concepts to refining your presentation and accuracy. These final guidelines are designed to help you avoid common pitfalls that often lead to minor mark deductions.
By following these specific instructions, you can ensure that your hard work is reflected perfectly in your answer sheet.
-
Stick to NCERT: Use the NCERT textbook for all definitions and laws, as the board follows its language strictly.
-
Be Precise with Laws: When stating laws like Ohm's Law or Fleming's Left-Hand Rule, do not skip keywords like "constant temperature" or "mutually perpendicular."
-
Accuracy Over Speed: In numericals, ensure you write the correct units (e.g., Omega, V, A, D). Missing units lead to unnecessary mark deductions.
-
Balanced Perspective: Do not spend all 8 hours on one subject. Ensure you give equal weightage to Physics, Chemistry, and Biology according to their marks distribution.
By following this 8-hour plan and utilizing the revision sessions, you will be well-equipped to handle the CBSE Class 10 Science Board Exam 2026 with confidence and accuracy.
