Dear Sir, 620 is a pretty appreciable score in the NEET. With this you xan easily cross the cut-off for AFMC which was 551 for boys. After which you need to appear for a test of their own in English and Reasoning and the total score will come out to be 720+80=800 which will be divided by 4 and brought to whatever you score out of 200. Based on this score, you get admission.
