Hi, 

Actually there is NO reservation for defense quota students in NEET. The ultimate ground for judgement is your score but after declaration of results, you can get complete information regarding this is your state counseling procedure. 

As far as your score is concerned, I think you need to work more hard so that your score could get better next year. Don't get disheartened. Just work hard and keep calm. And continue your studies. 

All the Best!
