Dear candidate

500 is a very good score but if you belong to general category then inorder to get a seat in government  medical college you need to get atleast 550 marks otherwise you won't get seat if you belong to any other category no worries and It looks like you are incomplete with your question as you just mentioned that you got 500 marks in NEET  and you seek to get admission in a college but you just forgot to mention what college and what category  you belong which is important to know to predict whether you get into a college or not so mention what college you wanted to join so that I can help you with the Information you need.

Visit the NEET college predictor link to find out how many colleges you can get for your marks

Hope this Information is helpful
