(Post By Sanjay Soni) Qus;- How to get above 90 marks in chemistry ? Reply By IITians- Some important topics taught in Chemistry in class 12 are:- P-block elements,, D and F block elements,, Electrochemistry,,, Solid States,,, Chemical Kinetics,, Surface Chemistry Preparation Stratgy: 1) Students who are weaker in Mathematics and calculation should concentrate more on Organic Chemistry. Chemistry is a scoring subject. According to Chemistry question paper of past few years it has been seen that all questions are directly or indirectly asked from the NCERT books. So NCERT books should be read in a proper manner and one should remember it very well that there is no substitute to hard labour. Organic Chemistry carries 18 marks and it is one of the most important units in Chemistry for every student who wants to get better marks in the Chemistry. 2) In Inorganic Chemistry, p-Block Elements and d-Block Elements together constitute 13 marks. Though it a tough ask to mug up both the chapters in a quick time, it would be ideal to study the notes of these chapters. The questions from the inorganic chemistry are directly asked. 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 discrete manner and regularly. Because irregular study of inorganic chemistry can cost you very much and you tend to forget even the already learned topic too. 3) 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. 4) Physical Chemistry should be read in appropriate manner. First of all, each formula from each chapter should be learned. Students should then try to solve related problems based on those formulas. Theory part should also be learned from those chapters as they are often asked in the exam. 5) 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 attempt first. 6) If you tend to forget the learned topics then do not take much stress. It happens with every student. Prepare a time table and take out at least 2 hours daily for revising the learned topic. A regular revision can help you in securing higher marks in Chemistry. Tips for Preparation: 1.If you feel you are not good at Chemistry, start early. Start reading your NCERT book as soon as possible. 2.Do not try to rush and finish the chapters. You should understand that reading a book that deals with scientific concepts, theory and reactions is different from a novel or a comic. 3.Follow up your NCERT concepts with a reference book to gain a deeper understanding of the topic. 4.Start attending classes and laboratory lectures. Perform each and every laboratory experiment. For example, you might not remember Le Chatelier’s principle of equilibrium for reversible reactions, but if you perform the experiment, and see things happen, chances are, you will remember it for a longer duration. 5.Try and grasp the concepts and always ask questions. Make a list of unanswered questions and ask discuss them with a teacher or a peer. 6.Do not ignore numerical problems. Most of the times, the problems are direct application of the formulae in use, and, at times are mixed with your understanding of a topic. The numerical problems, if mastered are a good way to score marks. 7.After you finish your syllabus, revise as many times as possible. When you finish, do take the sample papers provided by CBSE in a timed environment. 8.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. Tips for scoring good marks: 1.During the exam, try to write your descriptive answers in points and give pictorial or graphical illustrations wherever possible. It enhances visibility 2.Scan the paper before answering 3.For long answer type questions, before starting, frame a skeleton of the answer in the margin. 4.Do remember the S.I units of all entities. 5.Be crisp and to the point in very short questions Recommended Books: 1.NCERT books for Chemistry are a must buy. 2.Pradeep’s New Course Chemistry for Class 12, is a hot favourite because of its simplicity in language and the number of problems it supplements it with. 3.CBSE Sample papers(e.g. EXAM IDEA).
