How many questions do I need to solve to qualify for ACM ICPC Gwalior/Kharagpur regionals in an AKTU college?

There are no fixed limitations as to the number of questions that need to be solved to qualify for ACM ICPC Gwalior/Kharagpur regionals. This usually depends on

• The level of difficulty of the questions. 

• The number of questions other teams of your colleagues have solved

Amritapuri regionals have a different selection process. They directly pick top teams from their ranking list.
