Hello Fathima
As NEET score, you need to have atleast 292 for better chances of getting a seat in government dental college. In 2018, a score of 292 secured a seat in ESIC Dental College and score of 296 got Government Dental College and Research Institute, Bellary. As there is difference of 12-16 marks between your score and last year's cutoff for admission in govt dental colleges, your chances of admission are close enough. However the cutoff for admission is different every year and for this year it'll be released soon, so you will have to wait until it is out by these dental colleges.
