Wise answer ahead…..
One of my friend has scored 631 marks in NEET 2019. It was his 3rd drop and also secured an AIR of 1600(approx)in AIIMS 2019. Two of my friend got 620+ marks in NEET 2019 in their 2nd drop(One of which secured AIR 316 in AIIMS ).
So according to me if you have potential and you dreamed for MBBS you can take 3rd drop .
Best of luck for your future.
