Hello Jitesh,

According to the previous year cut off, your score is enough to get a seat through state quota in Govt. Colleges in West Bengal. Last year the students who got 480 or more were able to get a state quota seat.

Bankura Sammilani Medical College, Bankura

North Bengal Medical College, Sushrutanaga

Midnapore Medical College, Midnapur

ESI PGIMSR Joka Kolkota

These are some of the colleges you can get at this score.

I am sending you the link where you can find the list of colleges in West Bengal with their cut off.
