Last year IIM Rohtak started 5 years integrated program (BMS+MMS) and give students the opportunity to get direct admission in IIM Rohtak by cracking IPMAT which is easier than CAT.
Candidate who are willing to give IPMAT exam must have 75% in 10+2 and the maximum age limit is 20 years.
After clearing the exam IPMAT,a candidate have to go through with GD/PI.
I Hope This Helps
Good Luck For The Exam!
