Hello,
With your score you have less chances of getting into PDU  medical college ,rajkot  as usually cutoff is around 530+ for UR category  under 85% quota (assuming UR as you havenot mentioned any category).

With 493 NEET score your Overall Percentile will be around  95.76 - 96.26  and your NEET AIR Rank will be around 56493 - 68643

However these information is based on last years cutoff and as cutoff changes every year depending on factors like difficulty and number of candidates and recent COVID19 situation etc.
