Hi

You have not mentioned the category you belong to so I am  assuming  you from general category if you belong to any other category then do let me know in comment .

It's quite difficult to predict that whether you will get a college or not as  cut off marks for medical colleges keeps changing every year  depending upon various factors like your domicile state , number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But when we go through previous data then it suggests that with 490 marks you hold a good chance for getting a seat in a Government Medical College

For example,
In neet 2019, 461 marks was the lowest marks that was required for general category for getting a seat in Bowring and Lady Curzon Medical College and Research Institute, Bengaluru under karnataka State quota
