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.
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.
Smart revision is more effective than studying for long hours.
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.
Knowing the pattern helps students focus on important concepts and manage time better.
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.
Even one missed NCERT concept can cost marks.
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 requires conceptual clarity and numerical practice. In the last two days, focus on formulas and important derivations.
Practice a few solved examples to improve confidence.
Organic Chemistry becomes easy when reaction mechanisms are clear. Focus on understanding reactions instead of memorizing blindly.
Prepare a quick reaction summary sheet for revision.
Inorganic Chemistry is scoring if revised properly because many questions are directly based on NCERT theory.
Read NCERT line by line for best results.
Formulas and chemical reactions play a major role in scoring marks. Quick recall helps solve questions faster.
Make sure to revise:
Keep a small formula sheet for quick revision.
Previous year papers help students understand important topics and improve answer writing.
Solve at least 2–3 papers before the exam.
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.
Good presentation increases marks even if answers are partially correct.

A structured revision plan helps students utilize the last two days effectively. Proper planning ensures balanced revision of all subjects and reduces exam stress.
Avoid heavy study on the last night.
