Hi

You need a score above 530

With a score of 530 your rank should be around 4500(AIR) . With this AIR , your rank in your domicile state will be good enough to get a seat in DMC Ludhiana.

There are a total of 1375 MBBS seats in Punjab out of which 590 seats will be available for state quota under UR category.

So, there's a genuine chance of getting admitted to DMC Ludhiana with that score.

Hope this answer helps.

All the best.
