How to Prepare for JEE Main 2024 Chemistry

The chemistry subject is divided into three parts- physical, organic, and inorganic chemistry:

Physical Chemistry

Candidates are suggested to keep a notebook so they can quickly revise any easy formulas for chapters like atomic structure, solid state, ionic equilibrium, electrochemistry, and thermochemistry. Be careful of the conditions in which these equations cannot be applied directly. The above topics should be given more attention because more questions are frequently asked about these topics. Also, keep in mind that log 2 (0.3010) and log 3 (0.4771) are important numbers to understand because they frequently appear in calculations.

Organic Chemistry

Candidates should focus on various name reactions they have encountered and their mechanisms in this section. The experts advise that questions relating to reactions like Ozonolysis, Aldol, Cannizzaro, Perkin, and Hoffmann should be regularly practiced. The GOC should receive special attention (General Organic Chemistry). One should be able to compare the stability of reaction intermediates as well as questions about acidity and basicity. It is important to thoroughly study isomerism and organic molecules containing oxygen. The evaluations of the various functional groupings should also be memorized.

Inorganic Chemistry

Here again, a candidate will be required to keep a note to record minor details about the composition of alloys and the formula of ores that frequently come up in objective questions. In addition to this, the emphasis should be on topics like chemical bonding, p-block elements, and coordination chemistry because these are the ones where the majority of exam questions are formed.

Ways to Excel in JEE Chemistry

Here are some pointers to excel if you are aspiring to score a healthy marks in JEE Main Chemistry.

Quality over quantity

Using too many reference books can leave you confused about which topic to learn from which book. This frequently results in leaving out a few things. Every student has a different understanding level, therefore you should choose books that are simple enough for you to understand. Prepare your notes once the topic and chapter have been covered.

Mock Test

The best strategy you can use to achieve a high JEE chemistry score is to take as many mock test series as you can. You can prepare for the JEE mains exam in 2024 by taking a series of practice tests based on the NTA paper pattern, which provides an idea of the kinds of questions that will be on the test.

Revision is the Key

Preparing for the JEE Main Chemistry 2024 revision should be a regular process. You should not delay revision till the completion of the whole JEE Main syllabus 2024 , you should keep revisions regular instead i.e. after the completion of every chapter. Regular revision will help you retain all the information that you have studied before. Regular revisions help you with your weak areas and make them strong. It also gives you an idea of the topics that you are lagging at.

Periodic Table

Before beginning your JEE Mains 2024 preparation, make a huge periodic table and tape it in front of your study desk. Finding the physical and chemical properties of the elements will be made easier by memorizing and recalling them.

Learn Formulas

Acquiring a thorough knowledge of radioactivity, kinetics, equilibrium, and chemical bonding formulas. You will have enough time in the exam to spare if you memorize the formulas. It will decrease the number of calculations as well as the possibility of errors.

Focus on all 3

Develop a strategy to dominate all three aspects of chemistry. To do well in the JEE Mains 2024, you must have a strong command of all three subjects.

Benefits of Studying the Topics Already Covered in Previous Exams

There are several benefits to solving previous years' JEE Main question papers.

The following are the top five benefits of solving previous years' JEE Main question papers:

  • Better Time Management
  • Practice Makes Perfect
  • Improve the JEE Main Preparation Methods
  • Get Familiar with the Exam Pattern
  • Evaluate the Areas of Strength and Weakness
  • Revise regularly what you study
  • Solve mock test papers

Time Management

Candidates are required to manage their time wisely once they start attempting previous years' question papers. One of the most significant advantages of solving previous years' JEE Main question papers. Besides that, it is regarded as a very good practice. It not only increases speed but also enhances accuracy over time. Moreover, time is crucial when taking any exam, and in the case of JEE Main, it is one of the most important factors.

Proper time management can produce significant benefits, and candidates can complete the paper on time.

Practice More

As the proverb goes, "practice makes perfect," thus everything that has been regularly practiced will result in improved outcomes. In this situation, students are automatically expected to perform well if they spend a lot of time studying questions from prior exams.  Other than that, using past JEE Mains practice exams is the sole way to gauge one's level of preparedness. The candidates can now assess their degree of readiness immediately.  Additionally, based on their evaluation, candidates might concentrate on bridging the preparation gap.

Know Your Exam Pattern

The JEE Main exam is one of the most difficult national-level exams, and competition is tough throughout the exam. As a result, to start preparing, the candidate needs to be aware of the exact exam format.

Evaluate Your Preparedness

As you go through the question paper, make sure to read it attentively. Mark the questions that are known, and leave the others blank. It is the best technique for responding to both known and hypothetical topics. Additionally, candidates can classify the exam in terms of difficulty level - difficult, moderate, or easy after completing JEE Main papers of previous years.

Solve Mock Test Papers

It is highly recommended that students regularly complete mock tests. Students can assess their level of preparation and improve their problem-solving skills by taking mock exams. Students are advised to finish three hours of timed online mock tests. Candidates who want to pass the JEE Main exams might select the NTA portal or any other website that provides free mock tests.

Revise Regularly What You Study

No matter how well you prepare, revision is still important before any exam. Exam preparation improves applicants' conceptual memory. Any topic that has been reviewed will help a candidate remember all the key details that they would otherwise be unable to or more likely to forget during the exam.

Improve JEE Main Preparation Methods

Improving JEE Main preparation should be the ultimate goal. By solving questions from the previous year, you can acquire a sense of the exam format and the number of questions from various sections of the course. Students should always maintain flexibility in their schedules and methods for studying for exams because of this. They will naturally be able to improve themselves and their preparation methods because of it. They can also set aside time to revise the most recent syllabus updates and concentrate more on their areas of strength and weakness.
