Hi

I am extremely sorry to inform you dear but with 73 marks cannot get a seat in any B A M S College be it government or private

This is because,

You have failed to qualify Neet examination as Neet 2020 cut off for different categories is

Category    cutoff percentile       cut off marks

General/ews       50                     720  -  147

UR-PWD            45                       146  -  129

Obc/Sc/st         40                      146  -  113

So , being from st category, you need at least 113 marks  to qualify Neet , thus with 73 marks you have failed in neet and so cannot get admission

So,
I suggest you to prepare again for Neet examination and don't worry we have Neet knockout program which will help you at every step of your preparation , the link for the same is given below
