Hello Saibsankar,
Assuming that you belong to general category I am very sorry to tell you that you have a very less chances to get admission in many of the government colleges in the west bengal. But you need not worry about it at all, as there are many private colleges in which you can get an admission based on the rank you have secured, 12th marks etc.
Hope this Helps.
Good Luck!
