I got 300 marks in neet can I get seat anywhere?

Hello kid,
.
Are you talking about NEET examination? If yes it depends on your category and your state. As we all know all the college's /state / category will not have same cut-offs. But yes, you may get a seat in private colleges or you can even try for management quota seats. Unless you are SC/ OBC category you can't give a try in government Colleges. Here I'm providing you a link of college predictor do visit it for knowing admission in college based on your score,

Hello
emmanuelmaremandla , You need to score the 50th percentile in order to qualify the NEET UG exam. So, if you get 300 marks , you are most likely to qualify the exam and would be eligible to apply in the medical colleges where cutoff marks are 300 or below. However, to get into top medical colleges, the expected cutoff is around 525 marks .  If you want to know about the seat on the basis of your marks in NEET 2020 then I suggest you to use careers 360 college predictor tool here:
