JEE Mains Syllabus
JEE Mains Syllabus – All You Need to Prepare

Abraham Lincoln once said, “If I had six hours to chop down a tree, I’d spend the first four hours sharpening the axe.”

Planning and strategizing things should be your first move if you are stepping ahead towards making your career with IIT JEE Exam.

Start from scratch if you wish to bag victory, the basic element needed is an updated and accurate JEE Mains Syllabus from which questions are expected in the JEE Mains Exam. Noting down important things and analyzing different topics would be the best approach.

Some key facts of JEE Mains Syllabus to align your hard work and preparation in the right direction are written below.

  • The syllabus will be having level similar to your 10+2 level.
  • The topics that you will cover in class 11th and 12th books will help in constructing the base for JEE Main 2018 syllabus.
  • But, you must give a thorough look upon the complete syllabus as there are some topics that could differ from your academic syllabus.

As per the JEE Mains Exam Pattern 2018, there will be 3 sections in Mains Paper 1 i.e. Physics, Mathematics & Chemistry, it is advised to deal with all the 3 sections with equal attention without neglecting any subject. Follow the same for Paper – 2 as well.

In JEE Mains exam, concepts taught in the NCERT textbooks will matter a lot while attempting the paper because the questions are usually picked up directly from there. Less amount of level of thinking is required to attempt these questions as about 30% of them are easy. However, “time constraint” is the biggest challenge faced by students and a lot of practice is required for scoring well in this exam.

JEE Mains Chemistry Syllabus – A compilation of all the topics

JEE Mains is the first phase of JEE and is conducted by CBSE every year to facilitate admissions into various undergraduate courses offered at NITs, IIITs, and other centrally funded institutes. As it is one of the toughest competitive exams in the world it is obvious that its preparation demands vigorous study.

It is very crucial to know about the syllabus before starting your preparations for JEE. The purpose of this separate article on JEE Mains Chemistry Syllabus 2018 is to let the student know about the content to be studied. Knowing the syllabus beforehand will help in better understanding of the topics relevant to JEE Mains 2018.

If you are good in Chemistry you can use it as an asset to fetch more marks in lesser time. If you have good bonding with the subject, you can solve chemistry part very soon. To get fruitful results you need to really work hard on the subject and have good understanding of it. Some questions in Chemistry section are asked so directly that you don’t even need to lift your pen, just tick the answer and move ahead. This is the reason why Chemistry is considered really scoring in JEE Mains exam.

All the chapters of Chemistry are divided into 3 Units as follows:

  1. Physical Chemistry
