Hi Dear,

Yes, you can get a call from Indian Institute of management even if you have low marks in class 12th and perform well in Common admission Test (CAT). Moreover, mere getting a call from IIM does not guarantee your selection. The final selection is based on many other factors like past academic records, overall profile of the student, performance in GD/WAT/PI round and work experience.

You can visit the link below for cut offs of IIM for SC students:

Good Luck
