I got 523 marks in neet . Can i get govt. College in rajasthan through state quota.

Dear Sahil, you havent mentioned your Category. Neverhless, in 2018 under State Quota, the cut offs for various Categories have been as follows:
General Category: 530
OBC: 523
SC: 397
ST: 385

With 523 marks, it is difficult for a seat in a Government Medical College unless you belong to SC/ST Categories. If you belong to General/OBC Categories you might get a seat in a Private Medical College. 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 various colleges at:
