JEE Main 2019: Exam Analysis For Paper 1 (9 April - 2nd Shift)

JEE Main 2019: Exam Analysis For Paper 1 (9 April - 2nd Shift)

The second shift of today’s examination was of an overall moderate in difficulty level. However, in this shift, the mathematics section was said to be the toughest by students. Physics was from easy to moderate as per most of the students. Chemistry was still the easiest of all.

JEE Main 2019 Paper 1: Exam Format


No of Questions














Analysis for Physics:

There was more numerical based question in the physics section. More questions were there from 11th CBSE and were found to be tough. 

Physics had 6 questions from mechanics and 3 from semiconductors. Also, questions from Relative motion, Convex mirrors were there in physics. 

Analysis for Chemistry:

Chemistry section was easiest of all the three. Equal weightage was given to all organic, inorganic and physical chemistry.

There were more questions from organic chemistry Sn1 and Sn2 reactions. Also, the Stratosphere question was reported as the easiest question. 

Analysis for Mathematics:

The mathematics section in this shift was the toughest of all. Although, Pattern and difficulty level is the same as the January session.

There were questions from coordinate geometry, 2D And 3D and calculus in maths. Also, the mathematics section had questions from Eclipse, parabola and trigonometry.
