JEE main 2020: The JEE Main 2020 is carried out by the National Testing Agency (NTA) for admission to Bachelor programs in NITs, IIITs and other centrally funded technical institutions (CFTIs) etc. for the next academic year (2020-2021) in two phases. The first phase for admission to BE / B. Tech (Paper-1) and B. Arch / B. Planning (Paper-2) took place between January 6 and 9, 2020 and the second phase for admission to BE / B. Tech instead of (Paper-1) and B. Arch / B. Planning (Paper-2) will take place from September 1 to 6, 2020. Students have the option of appearing in one or both phases. However, the result will take into account the performance of the students at the best of the two stages.
What are the topics and what is the level of difficulty?
Clearing JEE (Main) is not a difficult task. A systematic approach to preparation will help students gain admission to one of the best National Institutes of Technology (NITs). JEE (Main) consists of the CBSE Physics, Chemistry, and Math curriculum plus some general topics from the 11th and 12th State Boards. About 25% of the questions in the exam paper are easy, 50% are average, and 25% are difficult. The cut-off for JEE (Main) is usually 65% for NITs and IIITs.
How do I prepare for JEE (Main)?
A two-year planned, organized preparation for JEE (Main) is all that is required. Each set of problems needs to be approached differently and with its own methodology. Regular practice makes a student confident about addressing the problems. Speed and accuracy are the keys to success.
When preparing for JEE (Main), reference must be made to books and learning materials that will help shape your conceptual understanding. Since the current pattern of JEE Main is a computer-based test (CBT), it is recommended that you have enough practice before the actual exam.
Pattern from JEE Main:
According to the latest template from JEE Main in January 2020, the total score for this paper was 300. The duration of the paper was 3 hours with a total of 75 questions, including all three subjects (25 each in Physics, Chemistry and Mathematics). In each subject there were 20 multiple choice questions (MCQs) with a correct option and 5 questions with answers as numerical value. The scoring scheme for MCQs was +4 for a correct answer, -1 for incorrect answers, and 0 for an untried question, while the scoring scheme for the numeric questions was +4 for a correct answer and 0 for an incorrect or untried question . The paper was only performed in CBT (Computer Based Test) mode.
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. Try to try the chemistry in the first lesson as it has a few simple questions. If you can solve these questions in the first lesson, you will feel safe. It has been found that when you are confident, your efficiency increases. Just read the concepts of thermodynamics and chemical equilibrium as some conceptual questions from these chapters will help you do well in chemistry.
1. Conceptual clarity, application skills and awareness of the prescribed curriculum should be the focus.
2. Practice the most important questions daily to develop speed. Pay special attention to topics like mole concept, chemical balance, and electrochemistry.
3. Be careful and patient with organic chemistry, paying attention to topics such as stereochemistry, GOC (General Organic Chemistry), and functional group analysis.
4. In inorganic chemistry, most questions are conceptual and involve structures, processes, and applications. Particular attention is paid to topics such as chemical bonding and coordination chemistry.
5. Particular attention should be paid to the subjects of biomolecules, everyday chemistry and environmental chemistry.
6. Particular attention should be paid to NCERT as JEE Main is entirely based on NCERT in chemistry.
7. Particular attention should be paid to the issue of drinking water. One should try to learn the threshold values for the different ions in drinking water.
Always try theoretical questions first and then questions that need to be calculated. It is advisable to avoid numeric questions for the first 10 or 15 minutes of the exam.
Tips for JEE (Main): Physics
1. Mechanics is a subject in physics that most experts consider less scoring. However, to add to the dilemma, this is also the topic that makes up the bulk of the JEE (Main) in terms of grades. So this topic cannot be neglected.
2. One must also try to focus on other assessment topics to ensure better performance, e.g. B. Optics, electricity and magnetism, etc.
3. Kinematics and particle dynamics are very important topics in mechanics that appear regularly in the JEE articles.
4. Read recent years of JEE papers and sample test papers to understand what to expect from the exam once you have begun solving advanced problems.
5. Following the general trends, mechanics, electricity and magnetism are the most important issues in terms of the number of questions asked in JEE in recent years.
6. Various topics of physics are listed in descending order of the grades they carry, depending on how they appear in the previous year’s work.
Mechanics, electromagnetic induction, magnetics, electrostatics and amperage (same meaning)
· Modern physics
· Optics & waves
· Heat and Thermodynamics
· Waves and sound
7. Thermodynamics is important from both a physical and chemical point of view. So focus on that too.
8. Since it has already been discussed that mechanics, electricity and magnetism are the most important subjects in physics, a clear understanding of the basic concepts in these chapters must be considered. Vector is a concept that students very often come across when dealing with any of these topics. Hence, efforts must be made to understand it properly.
Tips for JEE (Main): Mathematics
1. Previous JEE articles suggest that more attention should be paid to chapters such as vectors and 3D than probability or indefinite integration, since vectors and 3D give the examiner less leeway on the variety of questions. Another chapter is Complex Number, from which 2-3 problems are posed every year. Therefore, the mastery of complex numbers, vectors, 3D and the definitive integral must have top priority.
2. Taking into account the trends of the last few years, all topics were dealt with, with greater importance attached to the topics of algebra, analysis and coordinate geometry.
3. To answer questions about coordinate geometry, all aspects and the results of algebraic calculations of the properties of cones must be known.
4. In chapters of Calculus like Functions, Application of Derivatives, simple markings can be achieved if a graphical approach is taken.
5. Trigonometry with a lower weight should not be ignored in the evaluation. You have to capture all the important formulas in trigonometry. This is an assessment topic in math.
6. Chapters like Math / Determinants / Statistics / Mathematical Induction also need to be covered in order to get some quick grades as the questions from this chapter are relatively simple.
7. Read the major JEE papers from recent years and the sample test papers to familiarize yourself with the pattern of the exam.
