# JEE Main 2020 Preparation

### Let us start reading the preparation article Regarding JEE Main 2020

JEE Main Preparation Strategy 2020 -The highly competitive exam comes with some changes in the question pattern which requires aspirants to tweak their preparation accordingly. Here’s how to go about that…There’s an old saying, ‘The more you sweat in peace, the less you bleed in war’. It is indeed wonderful advice to JEE (Main) aspirants in the sense that better the preparation, lesser the worry during the tough exam.

The National Testing Agency (NTA)  which conducts the Joint Entrance Examination or JEE (Main) as it is popularly known, has notified the question paper pattern for JEE (Main) 2020 which differs from the 2019 pattern. Salient features of the revised pattern are:

• The number of questions has been reduced from 30 to 25 for each subject. However, the duration of the exam remains the same as before at 3 hours.

• 5 questions have been included with answers as numerical values. There will be no options for those questions.

• These 5 questions will not have negative marks

• Maximum marks a candidate can score has been reduced to 300. Last year it was 360 marks. The maximum marks are equally divided into 100 each in Physics, Chemistry, and Mathematics.

## JEE Main 2020 - New changes and their implication

Earlier, the time allowed to solve 90 questions was 180 minutes, i.e., 2 minutes per question. Now that the number of questions has been reduced to 75 while the duration remains the same at 180 minutes, candidates will get 2 minutes and 24 seconds to solve each question. Since the time allowed per question has been increased by 20%, it looks as if the difficulty level of question paper may be correspondingly higher, compared to 2019. This means the aspirants will have to enhance their preparation level to score well in the exam.

The 5 questions with answers as numerical values may have been introduced to test the conceptual and analytical ability of the students. This will eliminate the tendency of candidates to solve questions by option elimination methods or through other options like guesswork and score well, despite insufficient knowledge about the subject. However, it will definitely favour the candidates who know the subject in-depth and have a knack for solving problems.

Earlier, candidates aspiring for B.Arch /B. Planning courses had to get through JEE Main (Paper-2) consisting of three tests - Mathematics, Aptitude, and Drawing. However, for the 2020 exam, the NTA has come up with a separate test for B.Planning aspirants which does not include a drawing test. This test will contain 25 objective types of MCQs specific to Planning.

Syllabus for B.Planning test is as follows:

• General Awareness regarding development issues, government programs/schemes, etc.

• Comprehension, critical thinking and analytical skills, graphs, charts, and map reading skills, simple statistics

• CBSE Class X Social Sciences

To prepare for the B.Planning test, one is advised to regularly follow the news with special focus on development related issues, schemes or government programs. One may refer to NCERT textbooks of Class 9 & 10 to understand the basics of history, geography, economics, and politics. One must also possess functional knowledge of map reading; a few google searches and some good articles online shall suffice to develop the necessary map reading skills for this test.

## JEE Main Preparation Strategy- Mathematics

Syllabus for Maths is vast and diverse too. It may be broadly categorized under five sections, i.e., Algebra, Trigonometry, Coordinate Geometry, Calculus, and Vectors & 3D Geometry.

ALGEBRA: Some of the chapters in this section, such as Set theory, Relation, and Function, Theory of Equations, Sequences and Series, are very simple and basic. These chapters will also help in other sections. Permutation & Combination and Probability may appear to be mind-boggling at first instance but once mastered, it may be high scoring sections.

TRIGONOMETRY: Despite having a small syllabus, problems based on this section can get very tricky and difficult. Good command over this section helps in solving Mechanics problems as well. To attain good command over Trigonometry, continuous practice is the only key. Derivation of the formulae will enable the candidate to tackle difficult problems with ease.

COORDINATE GEOMETRY: Candidates often avoid this section due to the voluminous syllabus. Except for a few initial chapters, Coordinate Geometry is perceived to be difficult because of the presence of conics sections. Often, students leave the conic sections in the hope of attempting easier questions from other sections. Since, it appears that the difficulty level of the question paper may rise this year, it is advised that this section should be prepared well.

One must learn to visualize the maths equations in the form of a graph. Many problems may be solved even without lifting a pen if one learns to visualise the maths equations in the form of a curve. Therefore, it is strongly recommended to buy a good book on Graphs.

CALCULUS: Historically, weightage of Calculus has been relatively low when compared to the efforts one needs to put in for its preparation. However, given its vast applications in Physics, preparation of calculus usually offers two-fold benefits. Among its peer sections, Calculus is indispensable and will remain one. It is advised that aspirants should practice calculus regularly to attain functional mastery over it.

VECTORS AND 3D GEOMETRY: Vectors and 3D geometry is a cakewalk if you have understood the basics of coordinate geometry.

It is believed that JEE shall shift from a direct formula-based approach to derivation-based solutions. In such a shift, those who have clarity of concepts and practiced continuously will benefit.

JEE Main Preparation Strategy - Physics

Physics is the most feared subject among JEE (Main) aspirants as it comprises a large number of concepts and numerous problems associated with each concept.  Syllabus of Physics may be divided into the following sections:

MECHANICS: Mechanics consists of many important chapters such as Kinematics, Laws of Motion, Work Energy and Power, Rotational Motion, Gravitation, Properties of Solids and Liquids, Oscillations and Waves, etc.

Good command over Trigonometry is a prerequisite for this section. Besides, tools such as Free Body Diagram, Force/torque equations, resolution of forces along the axis, laws of conservation of energy, momentum and angular momentum, etc. are instrumental to score good marks in this section.

ELECTRICITY AND MAGNETISM: Consisting of various important chapters like Electrostatics, Current Electricity, Electromagnetic Induction, and Alternating currents, Magnetic Effects of Current and Magnetism, etc., weightage-wise this is the most important section in Physics. Applications of tools such as Kirchhoff’s current & voltage law, Gauss’ Law and Biot Savart Law are key to this section.

OPTICS AND MODERN PHYSICS: This section consists of important chapters like Optics, Electromagnetic Waves, Atoms and Nuclei, Dual Nature of Matter and Radiation, Electronic devices, Communication Systems, etc. Optics and modern physics is the most scoring section of Physics. Further, the atomic structure is an overlapping topic with chemistry. The difficulty level of problems asked in Optics and modern physics may vary greatly. Since the difficulty level of the question paper may rise this year, it is believed that relatively a greater number of questions may be asked from this section.

WAVES AND THERMODYNAMICS: Kinetic Theory of Gases and Thermodynamics is an overlapping topic with Chemistry; hence, its preparation is mandatory.

Given the huge size of the Physics syllabus, it is advised that the aspirant should make a study plan for each chapter based on its historical weightage & difficulty level and sincerely follow the same. An aspirant must never forget that mathematics is the language of physics and to score good marks in physics one must be fluent in mathematics as well.

## JEE Main Preparation Strategy - Chemistry

Chemistry syllabus for JEE is spread over Physical, Inorganic & Organic Chemistry.

PHYSICAL CHEMISTRY: Many chapters of Physical Chemistry share the syllabus with Physics such as Thermodynamics, Atomic structure, Electrochemistry, Gaseous state, etc. Such common chapters shall be prepared necessarily. Mole concept is the most fundamental topic of Physical chemistry and should be prepared meticulously. It is the most straightforward section of chemistry which does not have an exception. In the anticipation of rising difficulty level, it is believed that weightage of this section may rise in JEE Main 2020.

INORGANIC CHEMISTRY: Chapters such as Chemical Bonding, Coordination Compounds, Hydrogen & its Compounds and Metallurgy have good weightage and are relatively easy. Though chapters like s-block, p-block, and d-block are lengthy, a regular revision may make them game-changers.

ORGANIC CHEMISTRY: Organic chemistry has always been a game-changer for toppers. However, students often fear it as they face difficulty in memorizing a large number of organic reactions. By understanding the fundamental concepts of organic reaction mechanisms, one may easily predict the products in an organic reaction. Further, IUPAC nomenclature, isomerism, named reactions are also important from the exam viewpoint.

Firstly, an aspirant must be thoroughly familiar with the periodic table of elements. To memorize the same, one may affix a periodic table on the wall of the study room. One must dedicate at least two hours exclusively to the preparation of chemistry. In those two hours, one may solve the numerical type problems of physical chemistry, or revise the theory of inorganic chemistry, or understand reaction mechanisms of Organic chemistry. It is very important to make notes of the lecture and revise from those notes repeatedly. It helps to memorize chemistry better and reduces reaction time in the examination.

## JEE Main Preparation Guide - Important points

Previous year papers give a fair idea about the difficulty level and pattern of question papers. Students appearing in January 2020 are advised to solve previous years’ questions in the month of December’19 and not before. Till then, the focus must on completion of the syllabus. Some of the other points they should keep in mind are:

SOLVING MOCK TESTS: Mock tests help one to assess his/her functional mastery/weakness across the syllabus, ranks one among his peers, keep one’s competitive spirit ignited, helps one manage the time on/off the exam and boost one’s overall preparation to another level; the level expected from a topper. On the significance of Mock tests, Konda Renu, JEE Main 2019, AIR 9 says, “Practice makes one perfect. I think we lose our exam fear, learn to manage our time and in short, we become familiar with the entrance exam system.”

JEE (Main) 2020 is a Computer Based Test (CBT). Therefore, opt only for CBT mocks.

QUESTIONS WITH ANSWERS AS NUMERICAL VALUE: Questions with answers as numerical value are usually asked in JEE advanced paper. To tackle those problems, one is advised to practice such questions from previous year JEE Advanced papers.

TIME MANAGEMENT: It is often seen that candidates fail to attempt all the questions due to paucity of time. However, the 5 questions with answers as numerical value attract no negative marking for a wrong answer and hence, it would be criminal not to attempt them. Give priority to such questions.

A final word - The pattern of JEE (Main) paper is ever-changing. However, it is often seen that concept-based questions are common in this exam. Therefore, the JEE aspirant needs to learn the fundamentals of the subjects and practice as many questions and mock tests as possible before the D-Day.

Hope these tips will you in your JEE Main Preparation!!!!
