HOW TO SCORE 100% IN CBSE CLASS 12 BOARD EXAM 2018
How to prepare different chapters of Chemistry for Class 12 Board Exam?
Chemistry consists of 3 portions- Physical chemistry, Inorganic chemistry, and Organic chemistry. All three portions are equally important and if you want to score higher on this subject then you must not neglect any portion.
- First of all, learn and understand the theoretical portions of this unit. Without understanding theory, you will not be able to solve numerically.
- Learn all formulas of chapters like Solid State, Solution, Electrochemistry and Chemical Kinetics.
- Make a list of all the formulas that you come across and revise them every day. It’ll do wonders for you
- Solve numerical regularly to increase your speed. Never neglect the theoretical portion which is equally important for entrance exams too.

“How many times have you counted the number of pages in “p-Block Elements” before actually learning it?” It will not help you.
- Inorganic Chemistry requires lots of learning work and you cannot escape from it. NCERT is enough for the preparation of this portion.
- In Inorganic Chemistry, p-Block Elements and d-Block Elements together constitute a major part. Though it is a tough task to mug up both the chapters as it requires lots of learning, it is advisable to read your textbook (e.g.: NCERT) as it will also help you with Competitive Exams.
- Prepare short notes of various processes, reactions, and preparations.
- Usually, the questions are directly asked from the textbook. So, by giving some extra time and with regular revision, you can easily score in Inorganic Chemistry.
- Students should practice the structures of different chemical compounds of p-block elements properly because they are often asked in the board exam.
In summary, inorganic chemistry should be read in a discrete manner and regularly. Because an irregular study of inorganic chemistry can cost you very much and you tend to forget even the already learned topic too.
It is probably the easiest but important portion of class 12 Chemistry. It is also very interesting and a scoring section provided you have understood the basic concepts
- Learn all organic reactions. Practice them by writing and keep revising reactions.
- Solve all word-problems of NCERT exercise. Alcohols, Phenols and Ethers and Aldehydes, Ketones and Carboxylic Acids are the two most important chapters in Organic chemistry.
- Practice reasoning questions related to acidic, basic characters, melting and boiling points, comparison of isomeric compounds, mechanism of named reactions e.g., Reimer – Tiemann; Aldol; Kolbe; SN1, SN2
- Some important topics from Organic chemistry are– Sandmeyer’s reaction, Nucleophilic substitution reaction, Optical isomerism, Electrophilic substitution reaction, Esterification, Reimer-Tiemann reaction, Kolbe’s reaction, Williamson synthesis, Rosenmud reduction, Gatterman-Koch reaction, Nucleophilic addition reaction, Clemmensen reduction, Wolff-Kishner reduction, Aldol reaction, Haloform reaction, Cross aldol condensation, Cannizzaro reaction, Hell-Volhard Zelinsky reaction, Carbylamine reaction and Coupling reaction concepts.
The last three chapters like Biomolecules, Polymer and Chemistry in Everyday life should be prepared really well. They together constitute 10 marks and students often dare to take these chapters lightly and it really affects their final marks in Chemistry.
TIPS FOR SCORING GOOD MARKS:
- Try to remain calm in the examination hall and read the questions properly.
- During the exam, try to write your descriptive answers in points and give pictorial or graphical illustrations wherever possible. It enhances visibility.
- Scan the paper before answering.
- Do remember the S.I units of all entities.
- Be crisp and to the point in very short questions.
- Try to solve sample paper on every Sunday at least. It will help you in time management and would give you an idea of which question should be attempted first.
- Also, have a look at the answers and the marking scheme provided, as no other source can give you a better judgment than the one provided by CBSE.
REVISION is the Key…
If you tend to forget the prepared topics, then do not take much stress. It happens with every student. Follow a timetable and take out at least 2 hours daily for revising the learned topics. A regular revision can help you in securing higher marks in Chemistry.
1.NCERT books for Chemistry are a must buy.
2.Pradeep’s New Course Chemistry and Modern’s ABC of Chemistry for Class 12, is a hot favorite because of its simplicity in language and the number of problems it supplements it with.
3.CBSE Sample papers(e.g EXAM IDEA,TOGETHER,EAD,TO THE POINT).
We hope these points help you prepare best for the chemistry exam for upcoming class 12 board exam. Good Luck!
