Many students find Chemistry challenging because it combines three different areas: Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. Each area needs a different study approach. Start by understanding the syllabus and chapter weightage.

Focus on high-scoring chapters first, but don't skip any topic. Your NCERT textbook should be your primary resource. Read every line carefully.

Physical Chemistry: Practice Makes Perfect

Physical Chemistry uses math and logical thinking. It can give you quick marks if you prepare well. Start by memorizing all formulas before diving into derivations. This builds your confidence and helps you solve problems faster.

Solve a few mixed numerical problems daily from NCERT and exemplar books. Keep a one-page formula sheet and note your mistakes for each chapter. This works great for quick revision.

Organic Chemistry: Focus on Patterns, Not Just Memorization

In Organic Chemistry, understanding patterns matters more than rote learning. Learn how functional groups behave, including their acidic and basic nature, nucleophiles, and electrophiles. For each chapter, pay attention to nomenclature, preparation methods, physical properties, and chemical properties.

Make lists of reasoning questions, named reactions, and mechanisms. Study all Organic Chemistry chapters together to see connections between topics. Create reaction roadmaps after studying. Practice predicting products, identifying reagents, and writing mechanisms in three to four lines.

Inorganic Chemistry: Read NCERT Thoroughly

Read your NCERT textbook completely. Pay special attention to graphs, tables, and diagrams since questions often come from these. Focus on preparation methods and redox reactions of important compounds like potassium dichromate (K₂Cr₂O₇) and potassium permanganate (KMnO₄).

Memorize lanthanoids and actinoids with their atomic numbers and electronic configurations. Understand lanthanoid contraction and how it affects properties.

For Coordination Chemistry, organize your study around nomenclature, isomerism, Valence Bond Theory, and Crystal Field Theory. Study diagrams of crystal field splitting and synergic bonding carefully. Practice all NCERT and Exemplar questions regularly.

What to Do Before the Exam

During the days before your exam, focus on revision and practice. Don't try to learn new topics. Solve question papers from the last five years. This helps you spot common patterns and frequently asked questions. Write your answers using NCERT language to match how board examiners evaluate papers.
