Dear Jabin, though one of the criteria for NEET is that you should score a minimum aggregate of 50%, it is also important you complete 10+2 with that aggregate. So even if your aggregate is above the required agregate, because you haven't completed 10+2 as a whole, you cannot appear for NEET. You are called 'Passed' onlybif you pass in all the subjects of your 12th.
