486 was the least cutoff last year in Haryana in 2018. The college was Pt Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences, Rohtak. The competition and cutoffs have increased heavily this year since the number of candidates had increased and also the paper level was called easy comparatively. So can't guarantee you a seat in Haryana even with 526 marks but do try and best wishes to you.
