JEE Main 2018 Syllabus with Weightage

CBSE, the exam conducting body defines JEE Main Syllabus. The syllabus is defined separately for each subject- Physics, Chemistry, Mathematics and Aptitude Test for B.Arch/B.Planning. To obtain a good score in JEE Main, it is must to cover all the topics given in JEE Main 2018 Syllabus.  

Before delving into preparation, one should know about JEE Main syllabus and questions that are frequently asked. It will help a candidate to allocate their time and channel the efforts towards those topics that are considered important by JEE Main exam setters. Being familiar with that can help tremendously in JEE Main Preparations.

  • The syllabus for JEE Main is of class 11 and 12 level.
  • The exam consists of 2 papers- Paper 1 and Paper 2.
  • Paper 1 carries 3 sections- Physics, Chemistry and Mathematics. While Paper 2 comprises of questions based on free hand writing, geometrical drawing and 3-D drawing.
  • All the sections of respective papers are compulsory to attempt.

It is expected that JEE Main Paper 1 would be completely online. It may be possible that candidates can appear multiple times a year for JEE Main 2018. There will be 90 questions of 4 marks each in JEE Main Paper 1 that have to be completed in a duration of 3 hours. JEE Main Paper 2 will consists of 82 questions that have to be finished in 3 hours.

The following article on JEE Main Syllabus describes all the important chapters & topics along with the weightage of the marks.
