Hello Aspirant!

You have secured 403 marks in the National Eligibility cum Entrance Test. As you have not mentioned your category hence I am considering it to be general. Hence with such a score you cannot get into any of the government medical colleges. You can rather opt for the private medical colleges(which would take admission without any donations). For knowing more about which non-profitable medical colleges would fall under your rank range, you can use the NEET College Predictor.
