  • There will be at least three to four questions from Surface Chemistry, which is also an important section for competitive exams.

  • Stereo-chemistry, s, p, d, f block elements, transition elements, surface chemistry, nuclear chemistry, chemical equilibrium, gaseous state and coordination compounds are a few topics which are scoring and yet students find a little difficult. These sections must be covered thoroughly as apart from the class 12 exam, these are also covered in JEE and other exams.

  • There will be maximum questions from Raoult’s Law, Adsorption isotherm, Molar mass determination, Packing fraction. Cover these sections in detail.

  • Questions on numericals will be from sections such as Chemical Thermodynamics, Mole Concept, Solid State & Atomic Structure. There have always been questions from Molecular Orbital Theory and hence it is considered important.

How to prepare for CBSE Class 12 Chemistry – Tricks and Tips

Here are a few strategies that will surely come handy for students who are looking for CBSE Class 12 Chemistry preparation tips. These strategies will not only help you cover the syllabus with ease; they will also aid in enhancing your performance on the day of exam:

1. Prepare an effective study plan 

It is very important for students to manage their time wisely while they are studying as studying in class 12 Science implies that they have to devote time to other exams such as JEE, NEET and so on. There should be monthly, weekly and daily targets and the study time table should be prepared in such a way that all the subjects are equally covered. Keep a separate time slot for concepts in which you are weak.

2. Strengthen your concepts

It is not only important that the concepts are clear from the basic level; students must also go through what they have studied already to strengthen their understanding and memory of the same. There is a tendency of neglecting the areas in which a candidate is weak. On the contrary, one is advised to keep a separate time slot for concepts in which they are weak. Getting in touch with the Chemistry teacher or any other expert faculty followed by practise is the best thing to do here. Another very helpful strategy suggested by experts in their preparation tips for CBSE class 12 Chemistry is group study. Doing this, students will be able to transfer what they have already learnt among themselves and make their concepts even stronger. The key point here is to avoid leaving any part of the syllabus untouched. 

3. Self-evaluation

Students preparing for CBSE Class 12 are advised to keep an extra time slot for practice of CBSE Class 12 sample papers as well as question papers from the previous years. This should be done after all topics from the syllabus have been covered and students must ensure that they solve the question paper within the designated time. Doing this will assist students in self-analysis, which will further help them identify the areas in which they are lacking and work towards their improvement.

4. Practice of numerical

Set aside a minimum number, say five, of numericals to practise every day. You can prepare conceptual questions from numericals which will also cater towards understanding the fundamentals of these. Once a student acquires a strong grasp on the formulas and concepts, the problems become easier to solve. Regular practise will build on speed and accuracy as well confidence during the actual test.

5. Make short notes

Mark concise notes of topics that students can get back to any time is a very helpful practice that everyone needs to adopt. This also helps on in remembering what they have learnt better and it becomes easier to revise from these short notes instead of going through the bulky textbooks once again.


6. Take short breaks

In between the study schedule, take short breaks and do things that will help you relax. This could be communicating with family and friends, listening to music, having snacks or going for a short walk. Overburdening yourself will only build on the stress and lower your concentration. The short breaks, on the other hand, will help you refresh your mind and retain the concentration for longer.

Exam day tips for CBSE Class 12 Chemistry

A few experts, while delivering preparation tips for CBSE Class 12 Chemistry, advise students to leave questions on Organic Chemistry to be answered towards the end as they are more complex in nature as compared Inorganic and Physical Chemistry.
