Hey Vishal.

NTA has released percentiles scored in JEE Mains today and not the total marks out of 360 as of yet.  These are the Normalised scores and not the raw scores. The percentiles are based on the relative performance of all those candidates which is calculated by transforming the scores into a scale ranging from 100 to 0 .

The total scores as well as the scores for each of the three subjects- Mathematics, Physics, and Chemistry will be released on 31st January for the January session of JEE Mains. Right now only the Percentile scores have been released.

Best of luck
