How Can I get 98% in the 12th CBSE Board Exam 2021 (PCM)?

As we all know, the Central Board of Secondary Education, abbreviated as CBSE, is a board of education for government and private schools. Board exams conducted by CBSE for class 12th play a major role in students’ life. Well, scoring 98% in Physics, Chemistry and Mathematics demand a great deal of hard work. Students who put in hard work and smart study strategies can score more than 98% in these subjects.

Yes! You can score 98% in the PCM of class 12th CBSE board exam. You need to discipline and consistent with your study. Here are some tips for you that will help you to score 98% in PCM. 

  • Prepare a well-laid-out plan. Research carefully about the exam pattern and syllabus. Find out your strong and weak points and work on them accordingly. Prepare a timetable as well. It will help you to manage your time more properly. 
  • Choose your study materials wisely. Following too many books will make you confuse. Take the help of your teachers and seniors to choose the study materials. As you know, CBSE follows the NCERT curriculum. Therefore, NCERT books should always be your first preference. You can use some extra reference books after completing the NCERT books. 

Here are my recommendations 

Physics: NCERT physics book of class 11th and class 12th, Concepts of Physics by H.C Verma, IIT Physics by D.C. Pandey.

Chemistry: NCERT class 11th and 12th book, Organic Chemistry by O. P. Tandon, Concise Inorganic Chemistry – J. D. Lee

Mathematics: NCERT class 11th and class 12th Mathematics, Mathematics by R.D Sharma (class 11th and class 12th), Cengage Mathematics book set. 

  • Check previous year question papers and make a list of the most important and repeated topics, note down their mark distribution, so that you know where to start. Start preparing topic-wise rather than chapter-wise. This is why figuring out the most important topics is essential. 

Here I have listed out a few important topics of Physics, Chemistry, and Mathematics for CBSE class 12th board exam. 


Topics: Bohr’s Atomic Model, Properties of Matter, Errors in measurements, Heat & Thermodynamics, Rigid body dynamics, Electromagnetic Waves, Semiconductors, Electromagnetic Induction & Alternating Current, Current electricity and capacitors, optics, photoelectric effects, kinematics, wave and sound, modern physics. 


Topics: The periodic table and Representative Elements, Transition Elements and Coordination Chemistry, atom structure, Thermodynamics, and gaseous state, Chemical bonding, Ionic Equilibrium, Chemical kinetics, Aromatic compounds, Alcohol, Alkyl Halide, and Ether


Topics: Matrices and Determinants, Vector Algebra, Limits, Continuity and Differentiability, Integral Calculus, Coordinate Geometry, Statistics and Probability, Complex numbers, Quadratic Equation, Sequence and series, Binomial theorem

  • Always focus on concepts. Just mugging up will not help. Try to grab the concept of every topic. Take the help of others if you face any problem. You can also take the help of some online platforms. 
  • Prepare notes of all the important theorems of Physics and Chemistry. You will get the direct question on those topics. Make sure that you do not lose marks in those easy areas.  
  • Maintaining consistency will not only keep you motivated but also help you to push your boundary. Maintaining discipline is also important. Be regular with your study at home and try to be regular in school, coaching classes, etc. 
  • Revise as much as you can. If you want the most effective results, then you must revise whatever you have learned so far. Make notes and go through them every day or every alternate day. Jot down all the formulas in one notebook and skim through them in your free time. 

I hope the above information will help you to score 98% in PCM. All the best!
