Neet score is 280, Obc cartogary tamil nadu state. how can u guide to get government college through AIQ

Thanks for detailed reply.

Please let me know the chances of government quota for bds for 280?

280 is not an appropriate score to get a college through All India quota. Through all India quota the cutoffs are usually higher and that is why any score at least less than 550 out of 720 is less. Even for Dental, you need to secure at least 500 marks for OBC Category. You can check last year's all India cutoff of various medical and dental colleges here http://medicine.careers360.com/articles/neet-cut-off-for-government-colleges However you can try for state counselling as for state quota candidates the cutoffs are comparatively low and the private medical colleges participate in state counselling so you have chances to get seat in private medical colleges.

If you wish to appear for All India quota counselling, you can. Registration process for All India counselling will start from October 27. http://medicine.careers360.com/articles/neet-counselling
