See, the scenario will be entirely different this time. Till now, in many of the colleges across different states, only 15% of the seats were allotted for all India quota. Now as there is only NEET, the remaining seats will also be included in the bag, hence it is difficult to predict the scenario.
But irrespective of the situation, a score of 550 should bag you a good medical college. 500 is a must in case of a difficult or awkward type of paper.
