Hi

You have tagged SMBT Institute of Medical Sciences and Research Center, Nashik in your question so I will be answering with respect to that

You have not mentioned the category you belong to so 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 into a SMBT Institute of Medical Sciences and Research Center, Nashik

For example,
In neet 2019,  477 marks for general category got a seat in SMBT Institute of Medical Sciences and Research Center, Nashik under Maharashtra state quota

But yes you can go for private medical college and deemed universities
