Dear Manas, you havent mentioned your Category. Neverthless, in 2018, the cut offs for various Categories have been as follows:
General Category: 508
SC: 420
ST: 281
With 512 marks if you belong to General Category it is a close call. But she has a fair chance if she belongs to Reserved Categories. 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 each college in Odisha at:
