JEE Main Maths syllabus: Important topics and Preparation tips
Joint Entrance Test, popular as JEE, is a premier engineering entrance test which is conducted by NTA. The test is conducted in two phases, JEE Main and JEE Advanced. JEE Mains is the gateway to get admission in various NITs, IIITs and CFTIs. Toppers of JEE Main are selected for JEE Advanced and after clearing JEE Advanced they get admission into IITs. JEE Main Maths Syllabus described below broadly.
JEE Main Maths Syllabus
JEE Main, thus, becomes a very important exam as not only it is necessary for getting admission into NITs and IIITs, but even if someone wants to qualify for JEE Advances, he/she has to score good in JEE Main. More than 12 lakh candidates appear for this exam every year and thus, the level of competition is huge. To clear this exam, candidates do need to do a lot of efforts.
Mathematics is an important section for JEE Main as it occupies 1/3^{rd} of the paper. So a candidate cannot even think to take this subject lightly. Let us take a look at syllabus and preparation strategy for Mathematics for JEE Main:
JEE Main Examination Pattern
JEE Main examination pattern is quite simple. The test is held in both offline and online mode and candidates have to answer 90 questions in 3 hours. There are three sections, namely Mathematics, Physics and Chemistry, each having 30 questions. Each question carries 4 marks and there is a negative marking of 1 mark for each incorrect answer.
For majority of courses the examination pattern is like as mentioned above. However, for B Arch course, the pattern is a bit different. For B Arch, JEE Main will have 50 questions on Aptitude and 2 on drawing and importantly, this paper will also have 30 questions on Mathematics. Timing and Marking Scheme will remain the same. JEE Main for B Arch is held in offline mode.
JEE Main Mathematics Syllabus
Syllabus for Mathematics under JEE Main is huge. But the majority of syllabus includes topics which a candidate has already studies. So candidates only need to increase the depth of their knowledge and need to solve higher level questions of concepts already studied. The syllabus for JEE Mains for Mathematics section in as follows:-

JEE Main Mathematics Preparation Tips
One thing that is clear is that candidates will need to have deep conceptual knowledge of mathematic concepts, in order to solve the questions of JEE. Therefore, doing the syllabus properly, along with needed amount of practice is necessary. So here are some preparation tips for preparing for JEE Main Mathematics:
Start preparation at proper time
It’s very important that you give yourself time to prepare for JEE Main. If you want to prepare during your 10+2, then start preparation right from the start of session. And if you want to prepare after your 10+2 , then you should give a whole year to JEE Preparation, thus should start right after your exams. As syllabus is huge and deep understanding is needed, proper time needs to be devoted.

Be good with basics
Before jumping on to high level questions, it is very important to be good at basics. So candidates, rather than cramming and mugging up formulae and shortcuts, should try to be good with basics. NCERT books are a great source for this purpose.
Do time based practise
Candidates must note down the time they take to solve each question. Solving a question correctly is good, but not at the cost of a lot of time. Therefore, focus should be on time based practice.
Identify strength and weakness
Now there will be many people who will suggest you to do ‘xyz’ topic, and other will suggest you to do ‘abc’ topic. However, the real secret is that you should yourself identify your weak points and strong points, and thus work collectively on them. It’s only you who knows where you are good and where you are not.
Give proper time to all subjects
Now this might seem unrelated to mathematics preparation, but it is very important to give time to all three subjects. Doing one subject all day might make you feel monotonous and may thus reduce your efficiency. Therefore, do study all three subjects every day to keep the rhythm correct.
Make a formula Sheet
Formula sheets might be available at many places, but it is very important that you make your own formula sheet, as you will be able to use it a better way. Also, things are easily traced back when they are prepared by us. Therefore, one should make his/her own formula sheet for Mathematics, rather than referring to someone other’s formulae.
Solve past year JEE papers
This tip might be written at the last, but probably this carries a lot of weightage in your preparation. Solving Past year JEE papers is a must as it introduces you to actual exam-like problems. Also, identify patterns and topics of most importance from these papers. This will take your preparation to next level.
JEE Main Mathematics Study Material
It is very important that one uses proper study material for preparing for JEE Main. Proper books and material expose to more type of topics and are a core part of your preparation. Here are some books which should be followed for JEE Main Mathematics:
Book Name | Publisher/Writer |
Class 11 and 12 Mathematics | NCERT |
JEE Main Complete Mathematics | McGraw Hill |
A MASTER Resource for Mathematics in JEE Main | Praful K Agarwal |
Objective Mathematics for JEE | R D Sharma |
Integral Calculus for JEE Main & Advanced | Amit Agarwal |
Differential Calculus for JEE Main & Advanced | Amit Agarwal |
The importance of this exam lies in its scope. There are a lot of colleges that grant admission under JEE Main and thus it becomes important that candidates studies for this exam properly. Studying all three subjects with balance is the key to get a good rank, thus candidates should follow a well made strategy for tackling this exam.

It is common knowledge that not many of you are big fans of Chemistry. But this should not stop you from getting a decent score. Chemistry is one of those subjects which can be studied selectively and yet you can aim for a 100% result. This is mainly because most of the concepts revolve around bond formation/ breaking and the periodic table. If your fundamentals in these topics are rock solid then preparing for JEE Main becomes easy.

JEE Main Chemistry Important Chapters:
Chemistry is regarded as the most scoring subject among he three. A good score in this section will enable you to clear the cut off comfortably. Aspirants often neglect this subject because of the numerous formula and reaction. It is however the least time consuming section with a high level of accuracy.
Class 11 and 12 CBSE syllabus forms the basis of questions in JEE Main. Candidates should study from the NCERT textbooks to clear all the basic concepts. The chapter wise syllabus for Chemistry is given below:
Names of Chapters | |
General Organic Chemistry | Surface chemistry |
Alcohol Phenol Ether | Atomic Structure |
Redox reactions | Gaseous State |
Chemical Bonding | Transition Elements |
Coordination Compound | Polymers |
P-block elements | Nuclear Chemistry |
S-block elements | Chemical Kinetics |
Aldehyde & Ketones | Mole Concepts |
Solutions | Amines and Diazonium Salts |

Preparation Tips
JEE Main (Chemistry) as questions asked are straight forward and direct. The difficulty level is low compared to Physics and Mathematics. It requires the least amount of time and time saved in this section can be utilized in the other two. It is independent from the other 2 subjects (except for Atomic Structure and Nuclear Chemistry) unlike Physics and Mathematics which are quite co-dependent.
Following are some preparation tips for Chemistry that can go a long way in improving your JEE Main score:
Physical Chemistry- This is the easiest part among the 3. Read NCERT textbook thoroughly. You should first go through the theory of all chapters and then start attempting questions. The questions asked often involve direct application of formulae. You can think of which formulae to use only if your basic concepts are clear.
Learn all the tables and important points given in these chapters. Memorize all the formulae of Chemical Bonding, Equilibrium, Kinetics, and Radioactivity. Keep an analytical and stoichiometric approach while attempting the questions.
Inorganic Chemistry- The NCERT textbook alone will suffice for questions on these chapters. Familiarize yourself with each and every line of the textbook for Inorganic chemistry. Questions are picked up from the textbook without any twists. Make use of charts and mind maps for qualitative analysis. Give extra attention to the chapters d & f block and Co-ordination compounds.
Organic Chemistry- The key here lies in mastering the General Organic Chemistry (G.O.C) part. You should understand the logic behind various mechanisms. If you are thorough with the mechanisms, reactions are a piece of cake. Learn common names of substances and also do not neglect the last few chapters (Biomolecules, Polymers and Chemistry in Everyday life). Use good reference books like OP Tandon and Morrison & Boyd.
Study Material
Aspirants must refer to certain books to up their game and have an edge over the other. They must choose these reference books wisely and use them only after studying from NCERT books.
