Dear Rupa, you need to have atleast 24 months of fullbtime experience by March 31st. So it is mandatory to have work experience. Every candidate is evaluated in Academic Credentials, Leadership Potential and Personal Attributes. They consider your 12th Grades, Graduation grades, Post graduation and certificate scores along with GMAT/GRE scores. However there is no cut off as such. Your letter of recommendationnshould speak for your Leadership skills and achievements.
