This is percentile score not percentage score .As this only tell about relative performance of candidate in particular session in which he appears for exam...You can calculate your score using this formulaYour score = ( your percentile ×total number of candidate in your session)÷(number of candidate  in your session who score equal to irless than your raw score×100).It is not easy whether you will get any college or not because in percentile of 50-70 maximum number of students lies ,So wait till NTA declares raw score and cutt off marks.

GOOD LUCK!
