Hi!

Raw Score is the score which you have literally scored in the exam. If you have scored Y marks out of the total marks X, then Y is the raw score.

It will be further converted to percentile or rank. Both these parameters varies every year depending upon the number of candidates attending the same exam. Finally you'll be allotted a seat in the college based on your Percentile or Rank, Reservation Category, choice of Course and College, etc,.

If you have any further clarifications, let me know!

Hope this is helpful!

All the best!
