- Metals and Non-Metals: Reactivity series, extraction, and properties.
- Carbon and Its Compounds: Covalent bonding, hydrocarbons, and functional groups.
- Periodic Classification of Elements: The periodic table, trends, and properties of elements.
3. Biology
Biology delves into life processes and the environment’s interconnected systems.
Key Topics:- Life Processes: Nutrition, respiration, transportation, and excretion.
- Control and Coordination: Nervous system, hormones, and plant responses.
- How Do Organisms Reproduce?: Reproduction in plants, animals, and humans.
- Heredity and Evolution: Mendel’s laws, traits, and evolution theories.
- Our Environment: Ecosystems, food chains, and waste management.
- Management of Natural Resources: Conservation of forests, water, and biodiversity.
Effective Study Strategies
1. Grasp Concepts
- Focus on understanding core principles rather than rote memorization.
- Use real-life examples to relate abstract concepts to practical applications.
2. Master Numerical Problems
- Practice physics numerical problems frequently, especially in electricity and optics.
- Memorize formulas and practice derivations to strengthen problem-solving skills.
3. Learn Chemical Reactions
- Group reactions by types (e.g., combination, displacement) for easier recall.
- Use flowcharts to map reaction processes and products.
4. Draw and Label Diagrams
- Practice drawing biology diagrams like the human eye, digestive system, and plant tissues.
- Label diagrams accurately and neatly to score extra marks in exams.
5. Solve Sample Papers
- Solve previous years’ question papers and sample papers to get familiar with the exam pattern.
- Time yourself during practice sessions to improve speed and accuracy.
6. Revise Regularly
- Create a revision timetable that revisits topics weekly.
- Highlight key points and make flashcards for quick revisions.
