Chemistry Preparation for JEE Main

The Joint Entrance Examination (JEE) Main is the most popular and widely taken entrance exam for getting admission to the engineering colleges of the country. Lakhs of students appear for JEE Main every year to secure a seat in the courses of Bachelor of Technology (B.Tech), Bachelor of Architecture (B.Arch), Bachelor of Engineering (B.E.), and Bachelor of Planning (B.Planning). Questions asked in JEE Main are from Physics, Chemistry, and Mathematics of the higher secondary level. Admission to all National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and Government Funded Technical Institutes (GFTIs) are done through JEE Main.

The competition of JEE Main is fierce in every academic session and the margin for error is extremely small. Hence, students prepare rigorously to beat the cut-throat competition and emerge victoriously. It is essential to perform well in all the sections of JEE Main in order to get a good rank. The Chemistry section of JEE Main is considered to be the most scoring among all the sections. Therefore, all JEE Main aspirants must prepare all the topics of Chemistry well so that their scope of getting higher marks increases. This article provides all the important tips to prepare for the Chemistry section of JEE Main. Students aspiring to give the JEE Main 2021 can follow these tips to ensure that their preparation for JEE Main chemistry is top-notch.

How to Prepare for JEE Main Chemistry?

Chemistry is the most rewarding among the three subjects that comprise the questions of JEE Main. Therefore, it is imperative that the students give special attention to the subject and are thorough with it. Here are some steps that can be followed for preparing for JEE Main Chemistry.

  • To begin with, the student must always assess all the sections carefully and figure out the parts in which he/ she will have to give more time. Allocating time to those sections accordingly will help the aspirants get a better grasp of the syllabus.

  • The best way to study is to make a schedule and stick to it. After a while, the aspirant can make certain alterations to the schedule as per the pace and understanding he/ she gets of certain topics in a few days. Once the preparation begins, it is easy to gauge how much time needs to be given to each topic and students should make a routine accordingly.

  • Being regular with the preparation is one of the most important aspects of studying for Chemistry for JEE Main. As the subject is quite vast and hugely theoretical, students will have to study for it regularly so as to keep the flow. It is only by giving time to the subject on a regular basis that a student can memorise all the topics.

  • Setting aside some time for the revision of topics that have been covered is also among the most essential aspects of preparing for JEE Main Chemistry. As the subject is quite theoretical, students will need to keep going back to the chapters they have finished so that they remain fresh in memory and the students are well versed with them.

  • Studying from several books is not recommended for JEE Main Chemistry. All candidates should stick to some good books and use them for their preparation. Referring to different books results in wastage of time in trying to understand the language and also builds incoherence. Students often get confused when they use books of different authors to study or practise as different techniques might be used in them.

  • Memorising certain parts of the subject like the Periodic Table, Atomic Weights, Atomic Symbols, Atomic Numbers, necessary while preparing for the Chemistry section. This saves a lot of time while writing the exam and increases the scope of scoring significantly. A major part of Chemistry needs to be memorised like certain reactions and bonds. This will help the candidate score more while also saving time.

  • Once the aspirant has started with preparation in a full-fledged way, he/ she must check the accuracy of his/ her answers and incorporate ways to improve in this area. Apart from this, the candidates must also try to increase their speed as the importance of time in the JEE Main exam is important. Solving certain questions in less time will give the student an opportunity to use that time in the sections of Physics and Mathematics and also in reviewing the answers after the completion of the paper.

  • When preparing for any exam, practising old question papers and doing mock tests is undoubtedly one of the most important parts. Practising helps the student in realising which areas he/ she has to focus on and how he/ she should approach a question. It is always better to have an understanding of the type of questions that are asked in the exam so that the student is mentally prepared and knows how to go about the questions. Therefore, practising old papers regularly is an extremely important step while preparing for JEE Main Chemistry in order to score well.
