This article orients a student towards 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 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 good hold over the concepts and should study all the three sections with full dedication. Listed below is the strategy followed for all the three subsections of 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 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 require a very less to zero calculations.
This part requires a solid understanding of bond structure of carbon and its compounds. If you are well aware 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.
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, 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 is not everyone’s cup of tea. You need to put 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 which cover the 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 the 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 number of questions you solve, the more clear your fundamentals will become. Not only at school level, but advance level of this subject is also taught in first year os engineering.
Important Chapters: Thermodynamics, Optics, Current and Electricity, Gravitation, mechanics, Atomic Structure, Rotational Mechanics
You cannot say that mathematics is the toughest subjects of all three, unlike you do not have strong hold 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 of Algebra, Trigonometry, Calculus, Geometry and Vectors. We would recommend beginning with 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 firm grasp over 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 practice. The more you practice, the brighter goes your chances.
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.
