Hi Harshit! I believe 95 percentile is your expected percentile for CAT 2018. In that case, firstly you should focus on your preparation and ensure that you get the percentile you are aspiring for. Secondly, your academic background is average, but owing to your work experience and startup idea (if you are able to impress the panel with it), there are chances that you would get shortlisted or convert IIM calls. You may expect calls from the following B-schools with 95+ percentile:

• New IIMs 
• NITIE Mumbai
• MDI Gurgaon
• VGSoM IIT Kharagpur
• DoMS IIT Madras
• IMT Ghaziabad
• SPJIMR Mumbai
