Dear candidate, 

As per your said marks and as per the last year cutoff trend you have almost very low chance to get seat in government medical college of west bengal state under the state quota benefit for obc.

Last year for the obc-a and obc-b category the closing marks was more than the 480+ closing for the government medical college of west bengal under the state quota benefit. And you have much less marks than that, so only you can hope for the best to go around. Otherwise go with some private colleges.
