With the rank you're mentioning you can check out these colleges accepting OJEE scores for MBA

• Regional college of Management
• School of Management, Centurion University of Technology and Management
• College of Engineering Bhubaneswar
• Krupajal Business School
• Bhavan Center for communication and Management

These are a few colleges you can expect but if you are looking for 100% placements then I'm afraid none of the colleges accepting OJEE scores for MBA gives you that. You can get a maximum of 20-30% placements from there.

But it's always better to have backups. You can appear for other management entrance exams on national level to get a good college.

Good luck
