I personally know a senior from my Institute, who inspite of being GEM (General-Engineer-Male) having 90/82/6.5 converted IIMC in 2020 after Securing 99.91 Percentile in CAT 2019 and had an excellent Interview and WAT Later on.

I would advise now to focus on stuffs you can change. Xth/XIIth/CGPA is something you cant change now, but you may still improve on 2 Aspects which will lead you to an IIM or for that purpose some good Management Institute.

1. Target anywhere above 99-99.5 Percentile. Isnt as easy to get on Paper and you need dedicated efforts.

2. Work on your Quantitative, Non Quantitative and PI Skills as well as imroving your Resume. Besides CAT Prep try adding Virtual Internships as well as Courses, Specializations & Projects which show your inclination towards Finance, Business, Data Analytics, Supply Chain and Management in General.

Take a CAT Training Program if required from some of the Good Coaching Institutions like TIME, Career Launcher or Virtually from Platforms like Unacademy. You need a Good Test Series as well as a comprehensive preparation for both CAT and the PI/WAT Procedures.

I believe with a good strategy, you will surely secure a seat in one of the Top 6 IIMs or for that instant, atleast in one of the NIRF Top 20 Management Institutions having neck to neck placements, faculty and infrastructure. Do apply for Management School of Old IITs as they have an excellent ROI, as well as appear for XAT and MAT as they too are Gateways to many Good B Schools.
