This article orients a student towards the right preparation strategy for IIT/JEE mains and Advance Exam for the core subjects i.e. Physics, Chemistry, and Mathematics. We will also be covering important topics which should be prepared thoroughly and also preparation for your boards in parallel.
Chemistry
Chemistry is the easiest and scoring one out of the three subjects. If studied well you can easily score 90+ marks out of 120 in JEE. You need to have a good hold over the concepts and should study all three sections with full dedication. Listed below is the strategy followed for all three subsections of chemistry.
Physical Chemistry
You need to have a strong memorizing capability while studying physical chemistry as this part requires a lot of cramming. Go through each and every chapter and practice the questions. Start with the NCERT book, then follow exemplars, and after that if time permits, you can study standard books. This section is mostly application based and the numerical requires very few to zero calculations.
Organic Chemistry
This part requires a solid understanding of the bond structure of carbon and its compounds. If you are well aware of how carbon bonds with oxygen and hydrogen, no one can beat you in organic chemistry. You need to have very strong over the reactions and the formation of ketones, aldehydes, carboxylic acids, alcohols, ethers, etc. you should know the mechanism followed in the reactions.
Inorganic Chemistry
Again something this requires totally mugging. If you are good at memorizing, you can score full marks in this section. You need to memorize all the formulas, the periodic table, the elements, and their reactions, etc. Make a notebook and prepare notes in it, this is the best way to learn inorganic chemistry.
NCERT books are like Holy Grail for the preparation of IIT/JEE you need to understand each and every line written in your NCERT textbook. Solve the exclusively designed NCERT exemplars for having a better edge over preparation.
Important Chapters: Mole Concept, Liquid Solutions, Equilibrium, Inorganic (Full), Chemical Kinetics, Benzene, Aldehydes and Ketones, Amino Acids and all organic reactions
Physics
Physics is not everyone’s cup of tea. You need to put in a lot of effort and hard work to master this subject. Don’t panic while studying the subject, if you do not understand the subject; better take coaching or study from online portals or tutorials. You can begin with Electricity and Magnetism, Newton’s Laws or mechanics, optics, Modern Physics, thermodynamics, and nuclear physics. These are the topics that cover most of the physics and are scoring as well.
Modern Physics is basically a formula-driven and calculation-based topic. Solve a good number of questions to get a solid understanding of the concept. On similar lines, thermal Physics or thermodynamics requires a good practice of numerical. Optics certainly requires a well understanding of refraction, reflection, diffusion, and interference concepts. The working of convex and concave mediums and lenses should be crystal clear in your mind.
Mechanics, gravitation, and center of mass should be covered side by side. You just cannot leave mechanics to the end. The more questions you solve, the more clear your fundamentals will become. Not only at the school level, but an advanced level of this subject is also taught in first-year of engineering.
Important Chapters: Thermodynamics, Optics, Current and Electricity, Gravitation, mechanics, Atomic Structure, Rotational Mechanics
Mathematics
You cannot say that mathematics is the toughest subject of all three, unlike you do not have a stronghold over the concepts. But if your basics and concepts are clear, no one can ever stop you from clearing JEE. Whenever there is a tie between two ranks, the one scoring high marks in maths is given the preference.
The main sections of maths comprise Algebra, Trigonometry, Calculus, Geometry, and Vectors. We would recommend beginning with the calculus part which is the most important section of mathematics. Around 40% of the questions come from this section. Calculus is very easy to learn and scoring as well. Then comes next is Geometry and Vector algebra. These are time-consuming chapters and require more effort from your side.
You need to have a firm grasp of the probability part. Be very careful while applying permutation and combination. Most of the students mix up both these things. The best way to score more marks in maths is to practice. The more you practice, the brighter goes your chances are.
Important Chapters: Limits and Continuity, Differentiation, Sets, Maxima-Minima, Integration, Parabola, Circles, Complex Numbers, Probability, Vector Algebra, graphs, 3D geometry
Some final Words
JEE can become everyone’s cup of tea but what you need is hard work, time management, accuracy, and speed. Start preparing from class 11, else 12 will seem burdensome as you will be preparing for both boards as well as engineering entrance exams.
