With just two days left for the CBSE Class 12 Chemistry 2026 exam, students should focus on smart revision rather than trying to learn new topics. This final phase of preparation is about strengthening concepts, revising important reactions and formulas, and improving confidence.

Many students complete the syllabus but lose marks due to weak revision planning or exam stress. A structured last-minute strategy can help improve accuracy, speed, and answer presentation.

This guide explains a practical 2-day revision plan, subject-wise strategies, and exam tips to help you score maximum marks.

How to Use the Last 2 Days Before the Chemistry Exam:

The final two days before the CBSE Class 12 Chemistry exam should be used for focused and smart revision. Instead of trying to study everything again, students should strengthen important concepts, revise key formulas and reactions, and work on weak areas. A planned revision strategy during this time helps improve confidence and accuracy in the exam.

What to focus on:

  • NCERT textbook revision
  • Important formulas and reactions
  • Previous year questions
  • Weak areas
  • Quick notes and summaries

What to avoid:

  • Starting new chapters
  • Reading multiple books
  • Long study sessions without revision
  • Learning difficult concepts at the last moment

Smart revision is more effective than studying for long hours.

Understand the CBSE Class 12 Chemistry Exam Pattern:

Before beginning revision, students should clearly understand the exam pattern and marking scheme. Knowing the types of questions asked in the paper helps in prioritizing important topics and preparing answers according to CBSE requirements.

Exam Pattern Overview:

  • Competency-based questions
  • Case-based questions
  • Short and long answer questions
  • Balanced weightage from Physical, Organic, and Inorganic Chemistry

Knowing the pattern helps students focus on important concepts and manage time better.

Focus Only on NCERT — The Most Important Source

At the last stage of preparation, NCERT should be the primary study material. Most board exam questions are directly or indirectly based on NCERT concepts, examples, and exercises. Thorough NCERT revision ensures better clarity and improves scoring potential.

How to revise NCERT quickly:
  • Read highlighted lines and definitions
  • Revise examples and solved problems
  • Focus on tables and diagrams
  • Practice back exercise questions
  • Review intext questions

Even one missed NCERT concept can cost marks.

Subject-Wise Last Minute Revision Strategy:

Chemistry has three sections — Physical, Organic, and Inorganic — and each requires a different revision approach.

A balanced revision ensures better preparation and improves overall performance.

Physical Chemistry Quick Revision Strategy

Physical Chemistry requires conceptual clarity and numerical practice. In the last two days, focus on formulas and important derivations.

What to revise:
  • All formulas and units
  • Important derivations
  • Numerical problem types
  • Graph-based concepts
Important Chapters:
  • Solutions
  • Electrochemistry
  • Chemical Kinetics
  • Surface Chemistry

Practice a few solved examples to improve confidence.

Organic Chemistry Quick Revision Strategy

Organic Chemistry becomes easy when reaction mechanisms are clear. Focus on understanding reactions instead of memorizing blindly.

What to revise:
  • Named reactions
  • Reaction mechanisms
  • Conversions
  • Reagents and conditions
  • Functional group reactions
Important Chapters:
  • Haloalkanes and Haloarenes
  • Alcohols, Phenols, and Ethers
  • Aldehydes, Ketones, and Carboxylic Acids
  • Amines
  • Biomolecules

Prepare a quick reaction summary sheet for revision.

Inorganic Chemistry Quick Revision Strategy:

Inorganic Chemistry is scoring if revised properly because many questions are directly based on NCERT theory.

What to revise:
  • Chemical properties
  • Trends and exceptions
  • Coordination compounds
  • Important reactions
Important Chapters:
  • Coordination Compounds
  • d- and f-Block Elements
  • p-Block Elements

Read NCERT line by line for best results.

Revise Important Formulas and Reactions:

Formulas and chemical reactions play a major role in scoring marks. Quick recall helps solve questions faster.

Make sure to revise:

  • Electrochemistry formulas
  • Rate laws in Chemical Kinetics
  • Solution concentration formulas
  • Organic reaction mechanisms
  • Named reactions

Keep a small formula sheet for quick revision.

Practice Previous Year Question Papers:

Previous year papers help students understand important topics and improve answer writing.

Benefits:
  • Understand question pattern
  • Improve time management
  • Identify important chapters
  • Build exam confidence

Solve at least 2–3 papers before the exam.

Improve Answer Presentation

In CBSE board exams, answer presentation plays an important role in scoring marks. Writing clear steps, proper chemical equations, and neat diagrams helps examiners evaluate answers easily.

Academic Tips for better presentation:

  • Write clear steps in numerical problems
  • Use proper chemical equations
  • Draw neat diagrams where required
  • Highlight key points
  • Follow proper format for long answers

Good presentation increases marks even if answers are partially correct.
