If you’re one among the aspirant whose desire is to grab an Engineering seat in NITs, IIITs, CFTIs GFTIs or other top colleges in India, then firstly you got to know the JEE MAIN 2019 chapter-wise weightage and important topics. To be more precise, it becomes a crucial tool that makes your preparation go on hot wheels as you eventually get to figure out the high scoring areas and build a strategic plan. In this blog, we’ve compiled the topic-wise weightage and subject-wise list of all chapters covered in JEE Main 2019 syllabus, mapped as per 11th Class & 12th Class.

As you are aware, the National Testing Agency (NTA) will hold the JEE Main twice a year from 2019 on wards, so the competition is nevertheless high. But, in the same way the probability of succeeding best rank is maximum by two attempts. Followed by NCERT syllabus, the JEE Main Paper 1 consists of questions from 3 major subjects – Mathematics, Physics and Chemistry. Coming to JEE Main Paper 2, the Architecture students get the questions from 3 sections, including Mathematics, Aptitude and Drawing.

Have a thorough analysis of the entire syllabus and formulate a suitable preparation strategy accordingly.

**JEE MAIN PHYSICS SYLLABUS & WEIGHTAGE **

The Mathematics subject of JEE Main 2019 will consists of 120 marks, i.e., 30 questions of 4 marks each. However, for an incorrect question, one mark will be deducted. Major topics under this section are Algebra, Trigonometry, Calculus and Coordinate Geometry Check out the detailed JEE Main 2019 Mathematics syllabus below
