Hello Pujal

Greetings

Raw scores can Not be calculated from the Percentile scores as Percentile scores are relative therefore You can only make a rough estimate of Your rank as In Your case It would be  360381.

The formula used for Percentile calculation are:

Total Percentile (T1P): 100 X (No. of candidates appeared from the session with raw score EQUAL TO OR LESS than T1 score/ Total No. of candidates appeared in the session )

Mathematics Percentile (M1P):100 X (No. of candidates appeared from the session with raw score EQUAL TO OR LESS than M1 score in Mathematics /Total No. of candidates appeared in the session)

Physics Percentile (P1P): 100 X( No. of candidates appeared from the session with raw score EQUAL TO OR LESS than P1score in Physics/ Total No. of candidates appeared in the session)

Chemistry Percentile (C1P): 100 X( No. of candidates appeared from the session with raw score EQUAL TO OR LESS than C1score in Chemistry/ Total No. of candidates appeared in the session)

Hope this Helps All the best.
