Nayan with your 68.4 percentile and OHU in your category you have a chance to get admission in the following colleges:

• Maharashtra Institute of Technology, Kothrud
• Sinhgad Technical Education Society's Sinhgad Inst of Mgmt, Vadgaon (Budruk)
• Parle Tilak Vidyalaya Asso.'s Inst of Mgmt
• Bedekar Inst Of Mgmt
• Gawde Inst of Mgmt 
• Mumbai Inst of Mgmt
• SASMIRA's Inst of Mgmt
• Viva Inst of Mgmt
• Raheja School of Business Mgmt
• Kohinoor Business School
• Deccan Edu Soc's Inst of Tech & Development

Actually, 68.4 percentile is a little low to end up with a top b-school. Even in some of the colleges I have mentioned above, it will be a little hard for you to get admission, you might need to wait till last round of CAP.

Feel free to ask if you have any more queries. All the best!!
