How to Prepare Chemistry for Class 12 Board Exam?



Chemistry is a scoring subject and students can obtain higher marks in this subject by putting in little hard work. Chemistry is a very important subject for both Board exams and various Competitive exams. One can easily score 95+ marks in Chemistry but you must study it regularly. Entrance exams like NEET and JEE Mains are conducted within a month after the completion of class 12 Board Exams. If you have command over this subject then you can really perform well in different competitive exams too.


Why students face difficulty in Chemistry?
Many students fail to score good marks in this subject. The only reason behind it is that they run away from it. If you really want to perform in this subject then try to eject chemistry-phobia from your mind as soon as possible. Believe me, chemistry is one of the easiest subjects in the science stream provided you study it with full concentration and consistently. You must read chemistry regularly or you will fail to prepare it well for the board exam. 



Important Chemistry Books for class 12 Board Exams 
NCERT is the most important book for the class 12 board exam preparation. We recommend you to go through this book first and try to solve exercise questions. In addition to it, you must solve some sample papers to get familiar with Application based and HOTS (High Order Thinking Skills) questions. Some of the best books which you can take help from have been listed below. You can buy these books from Flipkart at exciting discounts.


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 in this subject then you must not neglect any portion.

Physical Chemistry: First of all, learn and understand the theoretical portion of this unit. Without understanding theory, you will not be able to solve numerical. Learn all formulas of chapters like Solid State, Solution, Electrochemistry and Chemical Kinetics. Solve numerical regularly to increase your speed. Never neglect the theory portion which is equally important for entrance exams too. (Also Read: How to Prepare Chemistry for NEET? )

Inorganic Chemistry: “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. If you have notes then it is great. But, if you don’t have it and you are finding it difficult to learn from NCERT then you can opt for above mentioned books like Together with or Xam idea.

If you successfully learn this section, rest assured, you will get full marks from it. Direct questions are asked from it. Never leave them for the last moment. Give at least half an hour to this section daily and keep revising learned topics as well to avoid forgetting them. 

Organic Chemistry: It is probably the easiest but important portion of class 12 Chemistry. This section carries 18 marks. Learn all organic reactions. Practice them by writing and keep revising learned reactions. Solve all word-problems of NCERT exercise. Alcohols, Phenols and Ethers and Aldehydes, Ketones and Carboxylic Acids are the two most important chapters from Organic chemistry. 


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

Important Chapters
If you want to secure 95+ marks then concentrate equally on all chapters. For weaker students who want to get at least passing marks i.e. 23, it’s important that they prepare selective but important chapters and topics. Prepare all above mentioned topics of Organic chemistry. The last three chapters- Biomolecules, Polymers and Chemistry in Everyday Life carry 10 marks together. “p-Block Elements” and “d-Block Elements” carry 13 marks together. Surface Chemistry and Coordination Compounds should also be read well. Good command over these chapters can take your score way above passing marks. (Also Read: How to Pass in Chemistry in CBSE Class 12 Board Exam?)

REVISION is the Key…
Whatever you learn, keep revising them regularly. Many students complain that they forget learned topics after few days. It is a common problem. With regular revision you can overcome it. Try to solve sample paper at least once a week to feel confident about your preparation. Solve last 10-year question papers. First, prepare those chapters in which you feel comfortable.

  1. Hello,
    Thank you for this wonderful post. I must admit that I've just recently developed an attitude (after we learnt p-Block and all the inorganic chemistry in school), that chemistry is absolutely impossible to learn. But, thanks to you, I've realized that it's only impossible as long as I think of it as impossible. :)
    I have one doubt. In all the comments, you've suggested solving as many papers as possible. However, I still have a ton of portion left to learn in all the subjects. Do you recommend learning everything first and only then moving on to solving all the papers? Because, I feel clueless when I look at any paper right now :$

    Thanks once again :)

    1. Thanks for your appreciation.

      Solving more and more sample papers will help you in diffusing out the board exam fear and you will become much more confident. But at the same time I will suggest you to finish your exam portion first. In that case you can solve sample paper on weekly basis.

      Best of Luck

    3. Organic chemistry requires both learning and regular practice. Learn all reactions first and them try to practice them by writing and solving conversions.

    4. If you have read those 12 chapters earlier then there should not be any problem. If not, then it is a bit unrealistic target. I will suggest you to solve sample papers and focus on revision instead of learning new chapters.

Study easier chapters first. Organic chemistry is not that tough, just you need to do more practice and read selected topics.

      I have mentioned some important topics from organic chemistry above, prepare them first. Practice last 10 year question paper. Start learning inorganic chemistry now, direct questions are asked from them. Solid state and Solution can also be done easily. Don't run away from chemistry. The last 3 chapters carry 10 marks, prepare them well. You will get more than 40 in board exam.

Direct questions are asked from them and they are scoring chapters. Some important topics from Organic Chemistry have been given above, go through them first.

      Learn all organic reactions by writing them repeatedly. It will help you while doing conversions. Solve sample papers after completing every chapter to strengthen your answering skills.
