JEE MAIN 2017 – Physics Analysis

JEE MAIN 2017 – Physics Analysis : This post is an analysis of the previous years exam giving a good idea of which topic had more weightage,distribution of easy ,medium and tough questions in each topic,which class syllabus was given more emphasis, and so on.

Similar stats have also been made for Mathematics and Chemistry (paste link of maths and chemistry links here)

JEE MAIN 2017 – PHYSICS ANALYSIS

Lets do an analysis of the Physics Paper here. In the year 2017, the paper seemed to have more number questions with medium difficulty reducing the tough and easy questions by a certain percentage. Around 60% of the paper had medium questions and 36.67% in the easy level and 3.33% in the tough level. Some questions seemed time consuming with Heat & Thermodynamics , Current Electricity, Mechanics and Modern Physics had prominent questions in 2017. However a few topics like Unit & Dimensions , Rotations were totally absent.
