Hey Vinaya, 

You will be eligible for admission. 11th results are not considered for NEET, but 12th results are important. Since you've cleared your +2, you can get admission. It depends on the marks you've scored and the ranking you've, I'm sure you've already cleared the previous failures. Good luck. 

Dear Aspirant

If you are scoring more than 60 % on all the subjects in your class 12 examinations you are very much eligible for admission through NEET 2019.

NEET doesn't take into account your class 11 scores. So go ahead and attend all the counseling sessions.

also look through this site to get an idea of the colleges you might get into with the score you are having:https://medicine.careers360.com/neet-college-predictor?icn=NEET_clgpd&ici=exit-intent
