Dear Sir / Ma'm, with the score of 498, it will not be possible for you to get a seat under the 15% All India Quota Counselling, as the All India counselling has a very high cut-off of around 550 and above. So, you must aim at the 85% state quota counselling of your respective domiciliary state, where you will have improved chances as state quota counsellings have generally lower cut-offs.
