With less than 10 days to go for the JEE Main (I) 2019 registration (1^{st} September 2018), candidates should get hold of the complete JEE Main 2019 syllabus, which would ultimately help them prepare for the April session exam. Conducted by NTA (National Testing Agency), the Joint Entrance Examination Main has been scheduled to be conducted on 6^{th} January 2019 in 8 different sittings. Candidates can book their slots as per their choice and convenience.
The JEE Main 2019 Physics syllabus has two sections  Section A and Section B. Section A has the theory part with 80% weightage of marks, and Section B has the Practical Component (Experimental Skills) with 20% weightage.
