Hey,

At first many many congratulations for your result. Since NTA (National Testing Agency) hasn't released the  official cut-off details of 2020 for the top BAMS Instituions in different states till now, so we have to follow previous year's cut-off details to make any decision regarding their admission procedures.

According to the 2019's informations, to get chance in the esteemed BAMS instituions under EWS quota, one had to secure atleast 370+ marks in NEET UG examination 2020 to become qualified for top BAMS instituions where in this year your expected marks (500) is quite greater than that.

Though the cut-off marks change each year on the basis of several determining factors like number of appeared canditates, number of successful candidates, total available seats, difficulty level of the exam etc, still it can be atleast estimated that you've definite probability for getting admitted in several top and eminent BAMS Government Colleges even through 15% AIQ.

So don't need to be too much bothered in this regard.

Wish you all the best.
