• Solving previous year question papers will help you understand the exam pattern, time management, and frequently asked questions.
• This practice will also help you identify the important topics that need more attention.
• Try to solve papers under timed conditions to improve your speed and accuracy.

4. Work on Important Topics

Some of the most important chapters in Chemistry include:

• Physical Chemistry: Mole concept, Thermodynamics, Chemical Kinetics, and Solutions.
• Organic Chemistry: Hydrocarbons, Alcohols, Phenols, and Ethers.
• Inorganic Chemistry: p-Block Elements, d- and f-Block Elements, Coordination Compounds, and Environmental Chemistry.
• Pay extra attention to these topics as they often carry more weight in the exam.

5. Focus on Conceptual Clarity

• Chemistry is all about concepts, especially in topics like Physical Chemistry and Organic Chemistry. Make sure you understand the underlying concepts rather than just memorizing formulas.
• Try to solve problems related to each concept to strengthen your understanding.

6. Practice Numerical Problems

• In Physical Chemistry, many questions involve solving numerical problems. Practice problems related to mole concept, molarity, normality, and laws of chemical reactions.
• Practice regularly to improve your problem-solving speed and accuracy.

7. Use a Chemistry Reference Book

• Apart from NCERT, use reference books like "Physical Chemistry by OP Tandon" and "Organic Chemistry by Morrison and Boyd" for additional practice and concept building.
• Make sure to stick to the books recommended by your teachers to avoid confusion.

8. Create a Timetable

• Organize your study routine by creating a timed schedule. Allocate specific time slots for each chapter and topic, ensuring a balanced approach to all subjects.

12. Stay Calm During the Exam

• During the exam, read each question carefully and attempt questions you are confident about first. For multiple-choice questions (MCQs), eliminate incorrect options and focus on the remaining choices.
• Don’t spend too much time on a single question. Move on to the next one if you’re stuck, and come back later if needed.
