Hello Arkaprava !
As per the trends, the cutoff is most predictably going to raise it's bar. Accordingly, the cutoffs of different medical colleges in West Bengal would definitely skyrocket.
If we analyse the situation that of 2017 and 2018, we would see that Maldah Medical College, the last govt. medical college to be opted during counselling actually closed down it's shutters at 477 and 481 marks respectively, even if the cutoff is raised till 500. You would receive your seat by a slight margin.
I wish you all the best on your endeavor. Let's hope the cutoff doesn't reach that high.
Hope I could help you out.
Feel free to reach out.
