How to Score 100/100 in Chemistry in 30 Days | CBSE Class 12 Board Exam 2027

Main Ideas

• A 30-day preparation plan: The presenter argues that completing the Class 12 Chemistry syllabus in 30 days is possible with focused study, written practice, and regular self-testing.
• Study each branch differently: Physical Chemistry requires numerical practice; Inorganic Chemistry benefits from NCERT study and previous years’ questions (PYQs); and Organic Chemistry requires clear fundamentals and an understanding of reactions rather than memorization alone.
• Prioritize practice: The presenter recommends solving questions by hand, especially numerical problems, reactions, conversions, and mechanisms. He also emphasizes reviewing mistakes through chapter tests.
• Use NCERT and past questions: The strategy relies on NCERT coverage, PYQs, and additional important and competency-based questions. The presenter claims that many exam questions repeat familiar PYQ topics.

Syllabus and Stated Weightage

The presenter describes the syllabus as 10 chapters:

• Physical Chemistry — 3 chapters, 23 marks: Solutions, Electrochemistry, and Chemical Kinetics. Focus on numerical problems and theory.
• Inorganic Chemistry — 2 chapters, 14 marks: The d- and f-block elements, and Coordination Compounds. Focus on NCERT, PYQs, and reactions involving KMnO₄ and K₂Cr₂O₇.
• Organic Chemistry — 5 chapters, 33 marks: Haloalkanes and Haloarenes; Alcohols, Phenols and Ethers; Aldehydes, Ketones and Carboxylic Acids; Amines; and Biomolecules. Focus on conversions, mechanisms, named reactions, and other question types.

Suggested 30-Day Plan

Physical Chemistry — 7 Days

• Days 1–6: Cover the three chapters, two days per chapter.
  • Review each chapter using a revision video or, if time is short, a one-shot lesson.
  • Use the presenter’s formula and graph sheets for revision.
  • Work through PYQs and important questions.
  • Write out and practise every numerical problem rather than only watching solutions.
• Day 7: Test and review.
  • Take a self-test covering all three chapters, including competency-based questions.
  • Identify errors and revisit weak concepts.

Inorganic Chemistry — 5 Days

• Days 1–4: Cover the two chapters, two days per chapter.
  • Spend the first day studying the chapter and its NCERT content.
  • Spend the second day practising PYQs and important questions.
  • Write out and review key reactions, particularly those involving KMnO₄ and K₂Cr₂O₇.
• Day 5: Test and review.
  • Attempt competency-based questions from both chapters.
  • Correct mistakes and revisit problem areas.

Organic Chemistry — 18 Days

• Day 1: Strengthen the Class 11 foundations.
  • If needed, review nomenclature, isomerism, inductive and resonance effects, hyperconjugation, and electrophiles and nucleophiles.
  • The presenter recommends a three-hour basics lesson and written practice.
• Days 2–16: Cover the five Class 12 chapters, three days per chapter.
  • First two days: Study the chapter thoroughly, including NCERT material and questions. Practise questions while following lessons, and learn the chapter’s reagents and reaction flowcharts.
  • Third day: Practise PYQs and important questions in writing, including NCERT back-exercise questions.
• Days 17–18: Test and review.
  • Attempt competency-based questions across the chapters.
  • Identify weak topics and revise them.

Organic Chemistry Advice

• Build an understanding of the underlying concepts instead of trying to memorize reactions in isolation.
• Practise reactions, mechanisms, and conversions in writing.
• Review named reactions, distinguishing tests, reagents, acidic and basic strength, and theory questions.
• Use flowcharts and reagent lists as revision aids, then check whether you can apply them to questions.

Other Material Featured

The video includes a promotional segment for Woxsen University’s School of Technology and its B.Tech programs. The presenter discusses practical learning, specializations, placements, scholarships, and an admissions deadline. This segment is separate from the Chemistry study plan.
