The JEE main paper consisted of a total of 90 questions and each question was awarded 4 marks for the correct answer, -1 for an incorrect answer and 0 for an unattempted question. Overall the paper was a bit tougher on Physics side while Maths and Chemistry sections were comparatively easier. Below is the analysis of JEE Mains exam section wise.
Physics section was moderately difficult as it had fairly an equal distribution among easy, moderate and hard questions. The questions which are asked from 12th class syllabus are comparatively easier than the 11th class. Around 10-12 questions are concept based, 7-8 questions are direct formula based and some questions also involved lengthy calculations and answers based on calculus. If the student has a good hold on memorizing the formula and is able to apply the right concept to the questions, he/she can easily score 70-80% marks in this section by investing around 45-50 minutes.

Overall the maths section of the paper was moderate to easy. Some questions were tricky. Most questions were based on basic concepts. Questions asked from class 12 was tougher and lengthier than class 11. More questions were asked from class 11. 12-15 questions are direct formula based and some questions also involved lengthy calculations. If the student has good command on basic concepts, he/she can easily score 70-85% marks in this section by investing around 50-70 minutes.

The Chemistry section asked in JEE Mains exam consisted of 120 marks. As given in the table below, a total of 15 questions was asked from class 11 and 15 questions were asked from class 12. The chemistry section in this exam was easy vis-a-vis the other sections that are, physics and mathematics. In this section, 16 questions were easy, 12 questions were medium and 2 questions were tough, the detailed analysis of the difficulty level of questions is given in the table below. As this section was quite easy, so students were able to save their time for other sections.
The easy, medium and difficult questions were asked from the following chapters:
Easy: Chemical Bonding, Organic compounds containing Oxygen, Organic compounds containing Nitrogen, Metallurgy, p-block, Periodic classification of elements, Mole concept, Solutions, Haloalkanes and haloarenes, Hydrogen, General Organic Chemistry, Thermodynamics, Electrochemistry.
