Hi

You may not get a seat in a government medical college under Government quota with 450 marks even if you are from SC category .

For example,

In neet 2019, 462 marks was the lowest marks that was required for sc category for getting  mbbs seat  in a government medical college under government quota   under Rajasthan  State quota and it was for Government Medical College, Barmer

But cut off marks  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.

So , you should target at least 500 marks in your neet 2020 examination  to be on the safer side

Thankyou

Hello

You can get college in rajasthan by 15% all india quota and 85% state quota for which you should be eligibile

450 marks are very less for getting a government seat but you can still get with your sc category but still chances are less

you still have time, you should work hard till exam date and increase your marks and chances of getting government college .

you should score atleast more than 500 to get a government college

you can check cutoff details for rajastha n here
