Hi

What is your domicile state?

Your profile suggest that you are from West Bengal so I am assuming it as your domicile state

As you have not mentioned your category I am assuming you from general category

It's quite difficult to predict that whether you will get  seat or not as  cut off marks for medical colleges keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But when we go through previous data then it suggests that with 450 marks you may not get a seat in Government Medical College

For example,

In Neet 2019, 518 marks  for general category Was the lowest marks to get  a seat in in a Government Medical College and it was for COOCHBEHAR GOVT MEDICAL COLLEGE AND HOSPITAL under west Bengal state quota.

You have chances in private medical college and deemed universities

Dear student
At first congratulations and best wishes for your result .  You have not mentioned your category so I am assuming you as a general category candidate. I am afraid to say with this marks your chances to get government colleges are almost negative through All India counselling for 15% seats . You can still try in state counselling for remaining 85% seats . Different state counselling cut offs vary from each other.
For different states it depend upon availability of colleges, student number etc various things . You have not mentioned your state . You must mention that for us to answer precisely. You must go for your respective state's counselling. Though chances for you are tough for you in there also for government colleges. However you can get easily many private medical colleges.
