Hello aspirant,

PCM weightage in JEE Main refers to the relative importance of Physics, Chemistry, and Mathematics in determining your overall score. It indicates how much each subject contributes to your final rank.

Typically, in JEE Main, Physics, Chemistry, and Mathematics are given equal weightage. This means that each subject contributes 1/3rd to your total score. So, if you score perfectly in one subject and poorly in another, your overall rank will be affected accordingly.

I hope this information is useful to you.
