How To Prepare For 12th Chemistry – Tips

After getting the idea about the syllabus, now it’s time for some tips which will help you to prepare the subject chemistry in an interesting way, just follow and remember each point given below.

Go With NCERT

Complete your NCERT textbook first, read each and every topic given in NCERT book. This will help you to mark an idea about the topics and questions.

Complete the theory part first, as you know that the first 5 chapters consist of numerically based problems as well as the theory section. It is advised that you complete the theory part first.

Read, learn and solve each and every question from NCERT textbook because most of the questions in board exam come from NCERT directly even without a change.

After completing NCERT you can buy Reference books for 12th PCM, and prepare for the board exam from them.

Graphs, Diagrams, Definitions And Organic Chemistry

Practice and memorize the graphs, important diagrams and structures this may help you to get extra 10 marks.

Learn and memorize each definition as most of the paper of chemistry consists of definitions only. Clear your doubts with the help of your teachers before it gets too late.

Organic chemistry is always a weak link for most of the students, so give special attention to this section and learn each and every important name reactions. Learning name reactions from organic chemistry will help you to score 10 marks without any doubt.

The Special Notebook

Create a special notebook, and write down each and every important term you find during the preparation process on that notebook. Now give at least 1 hour every day on revising that notebook. This will help you to retain stuff more clearly.

Do not forget to solve the previous year question papers and sample papers, this really helps a lot. If you solve the previous year papers and the sample papers only, without even going through the NCERT or some other reference books, then also you can easily achieve more than 70+ marks(it’s true).

Find your weak points, work on them and make them your stronger points. This is necessary for scoring good marks in chemistry.

Practice each and every question from above pdf files with all your focus, and don’t let any question go. Each and every question given in above pdf files is really important to practice.

Hope I have helped you in this article, for any assistance, suggestion, and guidance you can comment your query below, and you will be answered with the best possible solution to your problem.

  17. Hi Mam. I am Diksha. I am very weak in chemistry although I understand chemistry very easily but unable to score good marks. Please help me. I am very much tensed and confused about this subject. How can I score good marks in chemistry?

    1. Hi Diksha.
      In subject like Chemistry you have to deal with both theory part as well as numerical part so you must have sharp memory to remember all the reactions and also be good in practical approach to do numerical. While studying organic and inorganic chemistry always keep a notebook with yourself and write down all the important topics, reactions etc and for inorganic make sure you learn all the formula by heart. Next thing is revision, which is quite necessary as it helps to remember all that you have studied. Keep yourself focused and do regular study. Don’t get nervous just work hard and you will score good marks for sure.

  18. Mam I am Akash. I am in great tension after getting my result even I had written chemistry paper well that I was sure to get at lest 40 in theory but got only 4 marks there also fail. Please help me out. Please give me information regarding the studies I have to do for exam in July.

    1. Prof. Divyanshi Sharma

      Hi Akash.
      There is nothing to worry about. According to the CBSE rule you have to pass in 5 subject out of 6. If you have failed in only one subject then that subject will be replaced by the additional subject. This means you don’t have to give compartment exam and you will be consider pass. But if you have failed in two subjects than you have give compartment exam of one subject. You have to work hard then for the compartment exam.

  19. hello ma’am,
    I have a question that is it enough to practice the questions (pdf) you have given above? I meant ,no need of any more reference?

    1. Prof. Divyanshi Sharma

      Hi Fazeela.
      Practicing form these paper will help you a lot absolutely. But to score good marks stick to NCERT books. If you are preparing for any competitive exams then you can study from reference books. You can read our post ‘Books For CBSE 12th Physics, Chemistry, Maths, Biology’ where you will find names of some good reference books.

  20. Hello ma’am I am average student can I score 90% marks? Should I take tuition?

    1. Prof. Divyanshi Sharma

      Hi Ranveer, look its all up to you, if you think that there is need of tuition, then you should take it. However, i always suggest students to focus on self study which is more beneficial.

  21. How i can prepare in 20dys organic nd phyisical chemistry plz help me ?

    1. Prof. Divyanshi Sharma

      Hi Prajjwal.
      Do the thorough revision of each and every topic clearly, because chemistry is all about revising with complete dedication. So, work hard, you will get good marks.

  22. Hello Mam
    I’m getting nervous because when ever i study and after a short interval of time i forget the things
    My organic is weak mam because I’ve not studied organic chem in class 11 so will it effect me in class 12 boards this year

    1. Prof. Divyanshi Sharma

      Hi Abhinav.
      Don’t get disheartened. You are forgetting because you don’t pay attention while you study. So, be dedicated towards whatever you are studying and you can understand organic chemistry only if you will revise it thoroughly and practice the reactions in it with complete dedication. So, as only one and a half month is left, utilize this time for the best. Work hard, you will get good marks.

    2. Thanks a lot mam.
      One more quest mam
      In my preboards my maths exam didn’t go well and next exam was chemistry , but bcuz of maths i was unable to concentrate on chem and scored only 40 out of 70
      so mam now I’m too stressed and worried bcuz in both the exams i didn’t scored well
      and mam any predictions for board chem marks by seeing my preboard marks
      mam can u suggest me a time table for studying plzzz mam

    3. Prof. Divyanshi Sharma

      Hi Abhinav.
      Don’t get nervous. Have some faith in yourself, once you will gain that, you will easily be able to score good marks. So, we recommend you just practice with full dedication, set a proper time table for yourself, giving much of your time to those subjects in which you are weak. Start practicing all the questions from sample papers and previous year question papers. You will definitely get good marks.

  23. thank you for providing us the list of important questions topic wise, now i will be more confident about the upcoming exam after solving your notes

  24. Hi mam
    I have problems in the organic portion but can you give me a trick so that I could score good in it.pls I need a help

  25. Hello Mam, i am very good and strong in the inorganic chemistry part(numerical, theory, p block,…) but I am very weak in organic chemistry i have tried to study it many times but i really don’t get interest in it and now only 2 months are left and i am preparing for IIT and boards too. please help me what should i do about organic chemistry

    1. Prof. Divyanshi Sharma

      Hi Vivek.
      Don’t get dis-heartened. Just keep on practicing as organic chemistry comes with practice. So, be concentrated towards what ever you study. Avoid distractions. You will get good marks.

    2. Thanks Mam, I was thinking that I should solve only last 7-8 years question papers because I did the same in class 10th and it was really very beneficial. I was thinking to not learn every reaction instead I will solve last 7-8 years question papers for both IIt and board. Will that work?

    3. Prof. Divyanshi Sharma

      Yes, it will absolutely work. In Fact, at this moment, when exams are so near, this is the best way to study organic chemistry.

    Thank you.

    1. Prof. Divyanshi Sharma

      Hi Hardik. Glad to see you contented with the pdfs. We are working on the short questions of different chapters in Chemistry. They will soon be uploaded here.

  37. Sir.This is a amazing website.which helped me a lot in overcoming the fear of exam
    Sir i cant remember reaction of p block and organic topics.Suggest me a way to remeber.

    1. Prof. Divyanshi Sharma

      Hi Priyaranjan. p-block generally seems to be one of the toughest chapters but it is not. Have a look on last 10 year previous year papers and you will be convinced that why i am saying so. You will find mostly the same questions in every paper and that is too the reasoning part. As i always suggest, stick on to your NCERT book especially for this chapter.

      Apart from it, if i talk about reactions, then you have to learn them. Yes, try to memorize by writing them again and again.

  38. hi mem im krish I havejust facing a problem with chemical reactions so what can i do? and my theory was very well in chemistry and haw i scores 90 in chem

    1. Prof. Divyanshi Sharma

      Hi Krishnkant. Scoring 90+ in Chemistry is not that difficult for you. You are confident in your theory part, all you need is to focus more on reactions and equations which are really very important. First of all, make sure that you are not just memorizing things, instead try to understand by learning the basic concepts.

      Try to study reactions by writing them down. It will help you.

  39. hello mam,please give me a trick to study p-block elements .it’s very difficult for me to learn all the reactions

    1. Prof. Divyanshi Sharma

      Hi Muskan. p-block generally seems to be one of the toughest chapters but it is not. Yes, have a look on last 10 year previous year papers and you will be convinced that why i am saying so. You will find mostly the same questions in every paper and that is too the reasoning part. As i always suggest, stick on to your NCERT book especially for this chapter.

      Apart from it, if i talk about reactions, then you have to learn them. Yes, try to memorize by writing them again and again.

  40. thank u so much sir .. this actually helped me alot nd actually gave me an idea that i should really prepare .. thnxx alot sir …

  41. If we practice previous year question papers, will we achieve 70 marks?

    1. Prof. Rajeev Mehra

      Hello Naveen, the question of practicing the previous years papers arises only when you have covered your syllabus properly. You can not solve questions if you have not done your syllabus properly. So, previous years papers are no good, if you have not cleared your concepts and covered the topics.

  42. I would like to get an answer key to your questions sir, just to be sure.

    1. Prof. Rajeev Mehra

      Hello Rudr, Our team is working on the answer key of the papers. It is taking some time, hopefully they will be completed within 2 week. So, stay tuned.

  43. Sir is the imp questions are enough for CET R this is only based for pic help me out sir

    1. Prof. Rajeev Mehra

      Hi Manova, i did not get your question. Please be more clear what you want to ask.

  44. This is really good and well maintained

    1. Prof. Rajeev Mehra

      @Darth! Thank you, we always wish to hear the same.

  45. I am Sneha & i am quiet confused with chem whether to mug it up or to take an interest in it. It is a quiet boring but interesting sub for me like boring for memorizing things but interesting for knowing certain reasoning . Please help me to sort out things.

    1. Hey sneha you should learn things with concept for each topic. This will help you to remember things for long time… Along with it you must notedown the concept and revise it from time to time… Tis will helpful to you.. Good luck.

  46. Hello! I just finished my 11th grade and about to step into twelfth grade. Everybody keep telling me that NCERT should be given the first prominence for board exams and competitive exams as well. Is it truly enough if I master the NCERT?

    1. Prof. Rajeev Mehra

      Hello Prithvi,
      It will be great if you master NCERT, and you will surely score good marks in board exam. But for competitive exams, you should consider reference books too, just to be on a safer side.

  47. Sir, I am confused over the organic part, what about, if i solve previous 5 year question papers. How much chances are there of same questions to be repeated.

    1. Chemistry paper usually comes easy as compared to physics and maths, if you solve upto 5 years papers then you can score the passing marks and put yourself in the safe zone. You could face 3 to 4 questions which are appeared in last 5 years.
      And for organic chemistry, mug up all the important name reactions, structural formulas and reasoning question answers, doing this can bring you at least 10 to 12 marks easily.

    2. it’s true that if we solve the question paper of last year, it helps in exam. But same questions will not come again. though the pattern will be same.

  48. How to prepare for organic chemistry so that i can get full marks in it? I am confused which type of questions will come, are they same as NCERT or different? Please! suggest me.

    1. Prof. Rajeev Mehra

      Hey! Abc,
      Nice Name by the way!
      Try to learn reasoning questions, naming reaction and formulas. I know that’s prity much organic chemistry, but try to learn as much as you can can. And the questions are almost same as NCERT, even it is said that 70% of the qustions comes from NCERT.

  49. Nice questions, Sir. I told my friends to watch this site because I was getting tired teaching them. You saved my time. I hope they can solve the questions because if they can’t, again they will eat my brain.

  50. I am little bit tensed about physical chemistry. Where to practice from?

    1. Prof. Rajeev Mehra

      Hi Riya,
      Since you are running out of time, therefore, i will suggest you to practice the previous year questions and sample papers. You should focus more on revision instead of learning new things.

  51. Very helpful website for students.

  52. Sir are these questions for organic ( chp. haloalkane to amines) are sufficient to score 18 out of 18 marks because my organic chemistry is week. Please Reply

    1. Yes sure, but there is no assurance that you will face the same question in board exam. These are the possible types of questions which usually comes in board exam. If you study and practice them then surely you will get benefit as compared to getting a zero.

  53. Thanks for your help, now I’m ready for my chemistry exam.

  54. Sir, it is a great product, but I am very week in organic.
    Can I get about 20 questions, which are most probable to come in exam of CBSE 2016?

  55. No questions for polymers, Sir.

    1. Hello Sham,
      There is no need of questions regarding this chapter, just learn polymers with there monomers and the structural formulas.
      Just by doing this you can score full marks in polymers.

  56. keep the good work up.

    1. Thank you Harman,
      Glad to know that this website was help for you. We will love to hear your suggestions to improve this website, so that we could help students more.
