Students preparing for the CBSE Class 12 Chemistry pre-board exams in 2026 can use a clear strategy to score high marks. This plan aims to help students achieve 95% or more in the subject. Chemistry is often seen as a challenging subject for science students, but it also offers a great chance to score well with the right approach.
The Class 12 Chemistry exam follows a specific pattern. The main theory paper is for 70 marks . The remaining 30 marks are for the practical test, which includes experiments and viva voce. For pre-board exams, all questions are based on the NCERT textbooks . This means students must thoroughly study the full syllabus prescribed by CBSE.
Focus on High-Weightage Chemistry Topics for 2026 Pre-Board
To secure excellent marks like 95% , students should create an effective study schedule. It is wise to prioritize topics that carry more marks first. After mastering these, students can move on to topics that have less weightage. This method helps save time and strengthens overall preparation. Here is a list of important chapters and topics that can help you score well:
| Chapter Name | Key Topics to Focus On |
| Haloalkane & Haloarene | Nuclear Substitution Reactions, Finkelstein & Swarts Reaction, Classification of compounds |
| Alcohol, Phenol & Ether | Oxidation Reactions, Acidic Nature of Phenol |
| Aldehyde, Ketone & Carboxylic Acid | Hydration of Alkyne, Acidic Nature of Benzoic Acid, Basic Nature of Amines |
| Biomolecules | Different Types of Carbohydrates, Difference between Fibrous and Globular Proteins, DNA vs RNA structure and function, Reducing vs Non-reducing sugars |
| Solutions | Solubility principles: Henry’s Law application, Osmosis and Osmotic Pressure, Colligative Properties and their applications |
Top Tips to Score 95% in CBSE 12th Chemistry Pre-Board 2026
These useful tips can guide students in their preparation to score 95% or more in the CBSE Class 12 Chemistry pre-board exam for 2026 :
- Prioritize Important Topics: Do not try to study everything at once. Divide your Chemistry syllabus into high-weightage topics and low-weightage topics. Spend maximum study time on chapters and topics that are known to fetch higher marks in the exam. This smart approach ensures you cover the most crucial parts first.
- Make Detailed Notes of Chemical Reactions and Formulas: Chemistry, especially Organic Chemistry, has many reactions. Students should write down all important chemical equations, mechanisms, and formulas. This includes those from Organic, Inorganic, and Physical Chemistry. Regular revision of these notes will help in memorizing them well.
- Practice Previous Year's Question Papers: The best way to get familiar with the pre-board exam pattern is by solving questions from past years. Practicing these papers offers a clear idea of the marking scheme, the type of questions asked, and how much time to spend on each section. This also helps improve speed and accuracy.
By using these strategies and tips, students can build strong preparation for their CBSE Class 12 Chemistry pre-board exams in 2026 . A planned approach can make a big difference in achieving high scores.
