Your NEET marks 264 and rank five fifty three four eighty gives small chance for government BAMS, because closing rank for government Ayurvedia for general or OBC is around one fifty thousand or less, some top states close around two hundred thousand, but five fifty thousand is bit high, so government seat is difficult, but you may try in less popular states or later rounds, still chance low
