hi,

the admission in btech course in KL university hyderabad is done on the basis of kleee/ jee main/  ts eamcet scores, the basic eligibility criteria is the candidates need to pass 10+2 course from a recognized university  with 60% marks in aggregate. now 77 percentile is not enough for a direct admission even for your category, so i WOULD suggest you to directly contact with college authority for admission purpose.
