To prepare for your science exam, first go through the full syllabus and note the important topics. Make a simple timetable and give more time to the chapters you find tough. Read your textbook carefully, underline key points, and make short notes or diagrams. Practice numericals, equations, and diagrams regularly. Solve previous year papers and sample questions to understand the exam pattern. Revise everything at least 2–3 times before the exam for confidence.
