Most Important PCM Topics to Ace JEE Main
JEE Main is one of the most competitive examinations in the country. Every year, almost 1.2 million candidates appear for the JEE Main exam. If you wish to take admission in an IIT, you need to secure a good rank in JEE Advanced; for which you will be eligible if you qualify JEE Main. If you do not wish to appear for JEE Advanced, and if you obtain a good rank in JEE Main, you can take admission in one of the NITs, IIITs, and CFTIs. They are good colleges too. In any case, if you want to take admission in one of the prestigious government-funded engineering colleges, it is very likely that you will have to appear for JEE Main. Also, there are several good private engineering institutes that consider JEE Main scores for admissions. Hence, if you want to get admission in a good engineering institute, you should aim for obtaining a good score in JEE Main.
In this article, we will discuss about the most important topics in Physics, Chemistry, and Mathematics from the JEE Main perspective.
Important topics - Physics
The syllabus of Physics is slightly different for both JEE Main and JEE Advanced. There are several topics, for example, semiconductors, communication systems, etc., that are a part of JEE Main syllabus and are absent from the JEE Advanced syllabus. Many students ignore these topics in their JEE preparation since many coaching institutes focus on the JEE Advanced syllabus and skip these topics. For scoring high in JEE Main, it is essential that you study all the topics in the syllabus comprehensively. Almost every year, at least one to two questions appear in the JEE Main from these topics. Hence, you should not skip them.
There are some topics, that have somewhat higher weightage as compared to others. You should focus more on these topics. Some such topics are:
- Electrostatics: Generally, the number of questions asked in JEE Main from this topic is slightly more in number than any other topic. Hence, it makes sense to practice solving a lot of questions on this topic.
- Current Electricity: The questions of varying difficulty can be formed from this chapter. Almost every year, you can find a question from this topic in both JEE Main and JEE Advanced. This topic goes hand in hand with electrostatics and is taught in class 12.
- Rotational Mechanics: Almost every year, at least one question is asked from this topic in both JEE Main and JEE Advanced. Also, many students consider this topic to be pretty difficult. Hence, if you are very comfortable with this topic, you will be able to answer all the questions asked in the exam, which will give you an edge over many of your competitors in the exam.
- Atoms and Nuclei: Questions from this topic are very frequent in JEE Main. Also, since this topic is pretty easy, the questions from this topic are an easy win (of course, if you have studied it very well).
- Oscillations and Waves: This topic has a lot of formulas. Many direct questions are asked in JEE Main from this topic, that just require a simple formula application.
Important topics - Chemistry
In both JEE Main and JEE Advanced, the Physical, Organic, and Inorganic chemistry have almost same weightage. Hence, you should study all the three subdomains of chemistry very well if you want to obtain an overall high score in chemistry. Many students tend to put less efforts in studying Inorganic chemistry, which may cost them their JEE ranks.
Although you should study all the topics with utmost sincerity, some of the topics that generally have slightly higher weightage in JEE Main as compared to other chemistry topics are as follows:
- Chemical Bonding: This topic is a part of Inorganic chemistry, and is taught in class 12. A good understanding of this topic goes a long way and you can use the concepts you learn in this topic to understand many concepts in other topics as well.
- Chemical and Ionic Equilibrium: Every year, without fail, a question from this topic appears in both JEE Main and JEE Advanced exam. A good understanding of this topic is important if you want to score high in JEE chemistry.
- Coordination Compounds: This is a very important topic from which questions are asked almost every year.
- Heat and Thermodynamics: This topic is present in both physics and chemistry. However, different conventions are used in both the cases.
- Polymers and Biomolecules: This topic requires usage of memory with almost no calculation. Hence, the questions asked from this topic are a quick and easy win if you have studied this topic well.
Important topics - Mathematics
Mathematics requires a lot of practice. If you want to score high in JEE Main mathematics, it is very important that you understand all the concepts well and have practiced solving an ample of questions. Although the questions can appear from any topic in the exam, however, there are some topics that the paper-setters just can't spare. Some such topics are:
- Coordinate Geometry: This is a relatively easy yet lengthy topic in JEE mathematics. Although all the formulas in this topic can be easily derived using the fundamentals, it is important that you memorize the formulas well so as to save time during the exam. Conic sections, especially, have a lot of formulas. Parametric forms are important, so make sure that you are comfortable using them.
- Integration and Differentiation: Every year, without fail, one or the other question from these topics appears in both JEE Main and JEE Advanced. Being comfortable with these topics is important for developing proficiency in many other mathematics and physics topics as well.
- Permutations and Combinations and Probability: These are among the most confusing topics in mathematics. You need to solve a lot of problems so as to become comfortable in solving questions from these topics.
- Trigonometry: This is a relatively easy topic in mathematics. It involves a lot of formulas and is generally an easy score in the exam.
