Hi Devika, 

I really don't want you to get disheartened but the sooner you diagnose the disease, the better treatment you can get. First of all, NEET is only for getting admission into MBBS and BDS colleges (govt and private) don't confuse it with any other genre. For getting admission into vet and agriculture, you need to go through the brochures of different colleges who can provide you with these courses. Kindly go through the NEET related information once again on your own. And as far as your score is concerned, 200 is too less for a govt college and even for a good pvt college. I suggest you to join some good coaching Institute and get good guidance before you take up the exam next year. 

All the best!
