i fill the form neet I don't qualify what should I do ???

Since you have filled form,i highly recommend you to start preparing for it rather than thinking about the consequences of what might happen and what not. To qualify NEET you have to score a minimum of 50 percentile in general category which is quite easy to score even with a lesser preparation.
So start preparing for it, rather than thinking about the future happenings. Good luck!! For your exam.
