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.

You can use careers360 college predictor to know the colleges you can get at your NEET score:-

Hope this helps
