JEE Main 2021 Chemistry Preparation Tips By Mr. Ram Ratan Dwivedi - Joint Entrance Exam Main (JEE Main) is the national level test conducted by the National Testing Agency (NTA). Top engineering institutes in India like National Institutes of Technology (NIT), IIITs and GFTIs accept JEE Main scores for admissions to the B.Tech courses. NTA JEE Main is also a qualifier test for IIT JEE (JEE Advanced). JEE Main exam has a fixed exam structure and consists of three subjects – physics, chemistry, and maths. Paper-1 is of three hours and consists of thirty multiple-choice questions, 4 marks are awarded for correct answers and 1 mark is deducted for incorrect answers. The authorities have introduced a new JEE Main pattern.
Latest JEE Main Update: NTA JEE Main 2021 exam date announced; JEE Registration has started.
Important: Start the preparation by covering JEE Main 2021 Syllabus
JEE Main chemistry section is considered the most fruitful section in obtaining good marks in comparison to physics and mathematics. It requires a lot of practice of chemical equations, bonds and numerical. One should make a habit of learning by writing the equations as frequently as possible because they cannot be remembered orally.
It is considered as the rank deciding subject in most competitive exams because it comprises mostly theoretical based questions in comparison to physics and mathematics and so it is also the most scoring subject. The main strategy to score well is to analyse previous year JEE Main question papers and strengthen the topics which have mostly occurred. To make the study process more efficient you can check your performance through online test series which are based on the exam pattern. There are 15-18 tests papers for JEE Mains and 9-10 tests papers of JEE Advance, after giving tests you will get your performance report which will help you find your area of improvements and your speed.
JEE Main Chemistry Weightage Topics:
Physical Chemistry:
This section deals with the understanding and observing of the physical and chemical properties of different matter around us. It covers 40% of the JEE Main Chemistry paper and includes the basic concepts and formulae. A good tip is to make detailed notes on each topic and avoid skipping regular practice to crack these numerical questions.
Some important concepts in physical chemistry are:
Mole concept

Organic Chemistry:
It might seem difficult at first, but you can master this part with regular studying. The more you remember the reactions, structures and compounds thoroughly, the better. Do you know you can actually attempt this section in just 20 minutes if studied well? The trick would be to understand the fundamentals and mechanisms rather than learning by heart. Don't forget to make notes on the important topics and keep revising them every week.
Some important sub-topics for chemistry are:
Organic compounds containing Halogens, Oxygens, Nitrogen
Purification and Characterization of Organic Compounds.
Nomenclature
Inorganic Chemistry:
This is relatively much easier than any other section and doesn’t include any problem-solving questions. Therefore, this is a very time-saving section. Moreover, it contains very simple and straightforward questions that you can easily cover from NCERT XI and XII books.
Study the methods of preparation, uses, chemical reactions of compounds thoroughly as they are the important topics and cannot be missed.
Some important sun-topics in inorganic chemistry are:
Coordination Compounds
Classification of Elements and Periodicity in Properties
s-block elements (Alkali and Alkaline earth)
p-block elements
d and f block elements
Hydrogen
Practise conversions and reagents daily along with chemical reactions and their mechanisms. Daily practise and revision will help you make your mind stronger until JEE Main Exam.
With the right procedures, you can crack this hard nut without fail. You simply need to have self-confidence and keep practising via mock exams, which are extremely helpful. Remember, that this is the paper that can bring you the maximum scores, so do it well.

Hello Suhana
If you want to prepare for the JEE Mains exam 2026, then you need to manage your study time and try to give very much attention to your studies. JEE Mains is an entrance exam which is conducted by NTA(National Test Agency), and only science stream students give this exam to get admission in top engineering colleges to get admission in B.Tech or B.E courses.
Students give this exam after completing or appearing in the 12th class. This entrance exam is conducted at the undergraduate level. After clearing the JEE Mains exam, you become eligible to give the JEE Advanced, which helps to get admission in top IIT & NIT colleges of our country.
Here are some tips which help you at the time of your preparation-
I hope this information he;lps you. You also do your preparation on our official website, careers360.
All the best for your exam.
Hello,
Yes, you are eligible to attempt JEE Main 2026, as eligibility is based on appearing for or passing the class 12 exam in 2024, 2025, or 2026. Since you passed Class 12 in 2024, you are within the eligibility window to appear in 2026. Here in this article you will find more about the JEE Main eligibility criteria.
I hope it will clear your query!!
Hello,
If you have already passed Class 12 earlier and you are only taking the improvement exam in 2026, then you must choose “Passed” in the JEE Main 2026 form .
JEE Main always considers the first year in which you passed Class 12 as your official passing year. Improvement does not change that. So your status is not “appeared” and not “appearing.” It stays “Passed.”
You should enter:
Pass Status: Passed
Year of Passing: Your original Class 12 pass year
Marks: Your original marks (you can update later only if NTA allows it)
If you are giving Class 12 for the first time in 2026, then you must choose “Appearing.”
This is the correct and safe option for your JEE Main 2026 registration .
Hope it helps !
Hi Hriday
If your father's name is different on your Aadhar card and 10th marksheet, you need to change your father's name in the Aadhar card and match it with the spelling of the 10th marksheet, because when you take admission in college through JEE Mains score. They match your name, your father's name, and your mother's name with your 10th class marksheet, which serves as a real identity for document verification.
What college typically accepts-
I hope you will understand my point. These are some major issues which many students face during the time of admission in college.
Thank you.
Hello,
Yes, you can apply for JEE Main even if you do not have a caste certificate right now.
You only need the caste certificate if you want to claim a reserved category (SC/ST/OBC/EWS).
If you do not have it at the time of filling the form, you can apply as
General
or
General-EWS/OBC-NCL without certificate
, and later you can upload the valid certificate during counselling or document verification.
So yes, you can fill the JEE Main form without a caste certificate.
Hope it helps !
