JEE Main is one of the competitive exams which is the gateway for different engineering institutes of India including NITs and IIITs. It is also one of the hurdles that an IIT aspirant needs to cross, to be eligible for one of the toughest known exam “IIT JEE ADVANCE”. Roughly 20% of the registered students clear IIT JEE Main every year.
A set of 30 questions in each subject, Mathematics, Chemistry and Physics in a time period of 180 minutes (3 hours) is not a task that can be counted easy. One has to be fast and accurate while solving questions, since any mistake can lead to negative marking.
The marking scheme is quite simple for the exam, as every correct answer awards 4 marks and every incorrect deducts 1 from his aggregate total. So it is clear that one is being evaluated in a maximum score of 360.
JEE Main is one of the exam that is based on basic concepts and understanding of different principles/theorems that are being taught in 11th and 12th standard. The syllabus of the exam includes all the topics that are included in NCERT books.
The exam has all types of questions, some of them are based on principles (like Archimedes, Bernoulli, etc.), theorems (Pythagoras, Theorems for triangles, etc.) and applications of theory (Projectile, Equations of motion, etc.). It has both theoretical and numerical type of problems, with 4 multiple choices. Among the 4 choices, only one choice is most appropriate or correct.
One can follow multiple books to practice and learn the concepts that are required to crack the exam. The most recommended books for understanding of basic concepts for JEE Main is NCERT books (for all the three subjects). It is counted as a baseline material for JEE Main and learning all the principles, formulas and theorems. It is one of the best book for theoretical questions as some of the problems in JEE Main are manipulated from NCERT textbooks.
Once an aspirant has completed the theoretical study from NCERT books, he/she can refer below-mentioned books for practice and improving on their concepts.
There is one well known book by a professor in IIT Kanpur, naming “Concepts of physics by H.C Verma”. The book comes in 2 volumes(Concepts of Physics Vol.1 and Vol.2) and are the most recommended books for JEE aspirants. This book includes short answer type questions to sharpen one’s basic understanding. Also this book includes, single choice and multiple choice questions that can be very helpful to build up your concepts and apply whatever you have learnt in your theory. At the end of every topic, you can find exercise problems, which can be really fruitful to score good marks in JEE Main.
That single book can surely make you crack JEE Main with a very good score along with NCERT Physics book. If you feel you still have time, you can check DC Pandey (Arihant Publications) and Resnic Halliday.
Concentrate on NCERT for theoretical questions and learning of concepts including chemical reactions and formulas. NCERT chemistry can be referred for solving theoretical problems, but it doesn’t have good number of problems. For practice of problems and extending your knowledge towards different topics, you can refer these books-
For Organic chemistry-
- Organic chemistry by O.P Tandon
- Concept of Organic Chemistry by M.S Chauhan
For Inorganic chemistry–
- Inorganic chemistry by J.D Lee
- Inorganic chemistry by O.P Tandon
For Physical chemistry-
- Numerical Chemistry by R.C Mukherjee
- Physical Chemistry by O.P Tandon
Practice as many problems (numerical as well as theoretical) from the mentioned books when you are through with NCERT books and you surely can score really well in Chemistry.
Mathematics is considered as one of the subjects that play a vital role in cracking IIT JEE Main and scoring a good rank. For learning concepts and theorems, one can refer Mathematics NCERT book, but it doesn’t have very good level problems for practice.
For practicing Mathematical problems and to get idea of implementation of theorems/principles, you can refer these books-
- Objective Mathematics by R.D Sharma.
- IIT Mathematics by M.L Khanna
- Trigonometry by S.L Loney
- Geometry by S.L Loney
- Higher Algebra by Hall and Knight
Once you are through with the above mentioned books, you must practice mock test papers and solve previous year exam papers. Some of the mock test papers are released by JEE organising committee (CBSE earlier, NTA from 2019 onwards) and some are available from different publications. Some of the publications are-
- Arihant publications(Most recommended)
- Disha publications
- Balaji publications
Mock tests can help you to get an idea of where you stand and a rough estimate of how much you can score. The last two to three weeks before the exam must be dedicated to solving previous year’s problems. You should take last 15 year papers of IIT JEE Main and solve them. That will get you ready for your IIT JEE Main exam and you will be surely score really good.
Along with theory, numerical questions will help you boost your marks and get you a very good rank. As it is said for competitive exams-
“More you practice, closer you move towards scoring good marks”.
