Hey Biswanath,

There is no weigtage for 10+2 and grad marks. but for Admission in MBA or any other master program, it's required to have at least 50% in graduation some relaxation is for SC/ST. Some private universities might have lesser eligibility criteria as well. The weightage for TISS admission are:

• TISSNET Maximum Marks 100 Weightage 40%
• Pre-Interview Test Maximum Marks 50 Weightage 30%
• Personal Interview Maximum Marks 75 Weightage 30%
• Total Maximum Marks 225 Marks Weightage 100%
