Hey there!

Cut offs change every year therefore it is not possible to predict with surety how it would look like this year. But if we look at the trend in the JMI cut off, then it is usually very higher, so with your marks of 450, you have less chance of getting admission, unless some drastic change happens this year.

If you want to explore your options in private colleges and the deemed universities, you can use the neet college predcitor tool, here's the link- https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer

It will provide you extensive details of college you can get into based on your neet score.
