What are the subjects and what is the level of difficulty?

Clearing JEE Main is not a difficult task. The systematic approach to preparation will help students get admission into one of the top National Institutes of Technology (NITs). JEE (Main) consists of the CBSE syllabus of Physics, Chemistry & Mathematics and some common topics from the 11th & 12th of State boards. About 25% of questions in the examination paper are easy, 50% are average and 25% are difficult. The cut-off for JEE Main is generally around 65% for NITs & IIITs.

Exam Pattern of JEE Main

As per the pattern of JEE Main 2022, the total marks for this paper would be 300. The duration of the paper would be 3 hrs with a total of 75 questions to be attempted out of 90 questions asked from all three subjects (Physics, Chemistry and Mathematics). In each subject, there would be 20 multiple-choice questions (MCQs) with One correct option and 5 questions to be attempted out of 10 questions with answers as a numerical value. The marking scheme for all questions would be +4 for the correct answer, -1 for incorrect answers and 0 for an un-attempted question. The paper would be conducted in Computer Based Test (CBT) mode only.

How to prepare for JEE Main?

FIITJEE expert says a planned and organized preparation for JEE Main is all that is required. Every set of problems needs to be approached differently and with a separate methodology. Regular practice makes a student confident to tackle the problems. Speed and Accuracy is the key to success.

Books & study material which help in shaping your conceptual understanding must be referred to while preparing for JEE (Main). As the current pattern of JEE Main is a Computer Based Test (CBT), it is recommended to have enough practice of the same before the actual exam. For sample papers, one can download the same from the JEE Main official website and for further practice, one could refer to reputed sources which offer several mock test papers for practice and to gain familiarity with the actual pattern of JEE Main.

Tips for JEE Main Chemistry

It is observed that those who crack JEE Main are the ones who do well in chemistry. A week before the exam give 4 hours to brush up on your concepts of organic and inorganic for 3 hours and give 1 hour for Physical Chemistry. Try to attempt chemistry in the first hour as it has some easy questions and if you can solve these questions in the first hour, you will feel confident. It has been observed that if you are confident, then your efficiency increases. Just read the concepts of thermodynamics and chemical equilibrium, as some conceptual questions from these chapters will help you score well in chemistry.

1. Conceptual clarity, application skills and awareness of the prescribed syllabus should be the focus.
2. Practice the most relevant questions daily to develop speed. Pay special attention to topics like the Mole concept, Chemical Equilibrium and Electrochemistry.
3. Take a careful and patient approach to Organic chemistry giving attention to the topics like Stereochemistry, GOC (General Organic Chemistry) and Functional Group Analysis.
4. In Inorganic chemistry, most of the questions which are asked are conceptual and concerned with structures, processes and applications. Special attention is a must to Chemical Bonding and Coordination Chemistry topics.
5. Special attention should be given to the topics like Biomolecules, Chemistry in everyday life and Environmental chemistry.
6. Special attention to NCERT should be given as JEE Main is entirely NCERT based in Chemistry.

FIITJEE Recommends: Always attempt theoretical questions first and then questions which require calculation. It is advisable to avoid numerical questions in the first 10 or 15 minutes of the exam.

Tips for JEE Main Mathematics

1. Previous JEE papers suggest that more attention should be paid to Chapters like Vectors and 3-D than Probability or Indefinite integration as Vectors and 3-D offers very less scope to the examiner, as far as variety in questions is concerned. One more chapter is Complex Number, from which every year 2-3 problems are asked. Hence mastering complex numbers, vectors, 3-D and Definite integral must be on top priority.
2. Keeping in mind the trend of last year’s paper all topics had been covered with more importance given to topics of Algebra, Calculus and Coordinate Geometry.
3. To tackle questions from Co-ordinate Geometry all aspects and the results of Algebraic Calculations of properties of conics must be known.
4. In chapters of Calculus like Functions, and Application of derivatives one can fetch easy marks if the graphical approach is adopted.
5. Trigonometry through having less weightage must not be ignored as it is scoring. One must grasp all important formulae in Trigonometry. This is a scoring topic in Mathematics.
6. Chapters like Mathematical Reasoning /Determinants/Statistics/Mathematical Induction must also be covered to fetch some quick marks as the questions from this chapter are relatively simple.
7. Refer to past years’ JEE Main papers, and sample test papers to get familiar with the pattern of the exam.

Tips for JEE Main Physics

1. Mechanics is one topic of Physics that is considered less scoring by most experts. However, to add to the dilemma this is also the topic that forms the major portion of the JEE Main in terms of marks. So, this topic cannot be neglected.
2. One must also try to concentrate on other scoring topics to ensure a better performance, for example, Optics, Electricity Magnetism, etc.
3. Kinematics and Particle dynamics are very important topics of Mechanics that make regular appearances in the JEE papers.
4. Refer to past years’ JEE papers, and sample test papers to understand what to expect in the exam when you have started solving advanced level problems.
5. According to the general trends, Mechanics, Electricity and Magnetism are the most important topics in terms of the number of questions asked in JEE of previous years.
6. In the decreasing order of the marks, they carry are listed different topics of Physics according to their appearance in previous year’s papers.
   • Mechanics, Electromagnetic Induction, Magnetics, Electrostatics & Current Electricity (Equal importance)
   • Modern Physics
   • Optics & Waves
   • Heat and Thermodynamics
   • Waves and Sound
7. Thermodynamics is important in the terms of both Physics and Chemistry so concentrate on that as well.
8. As it has already been discussed that Mechanics, Electricity and Magnetism are the most important topics of Physics, it must be kept in mind to have a clear understanding of the basic concepts of these chapters. Vector is one concept that students very commonly encounter in dealing with any of these topics, so effort must be taken to understand it properly.
