I am scoring 625 in neet 2019 will I get a govt seat in kerala or aiq

Dear Mithun, 625 is a terrific score. You haven't mentioned your Category. In 2018, under State quota 597 marks scored a seat under General Category in Government Medical College, Kozikhode. This was the highest mark. Eitherways cut off changes every year and it depends on various factors like no.of seats available, no.of candidates appearing for the exam, top NEET score and difficulty of the exam. Considering the fact that General Category has thr highest cut offs, you have a shot at all Government Medical colleges. You can check their previous cut offs at: https://medicine.careers360.com/articles/neet-cutoff-kerala
Regarding a seat under All India Quota, it deoends on your Category and the State that you want to select. So if you have any State or college in mind, please do let us know and we will help you with their cut offs too.
