I got 545 in neet ,under un reserved category ,Svu region . I can get seat in government colleges sir?

Dear Venu, in 2018 under State Quota of SVU area, 516 marks secured a seat in Rajiv Gandhi Institute of Medical Sciences, Kadapa under General Category. Going by previous cut offs and your svore, you have a decent chance at:

GMC, Anantapur
ACSR Medical College
Rajiv Gandhi Institute of Medical Sciences, Kadapa.

Having said that, cut offs change every year and are dependant on various factors like no.of seats availble, no.of candidates appearing for the exam, top NEET score and difficulty of the exam. You can check the cut offs of your Category at:
