Help me in choosing 5 schools

You don’t shortlist universities based on your marks. The correct approach is :
Be very clear with your post-MBA goals. Post MBA, if you want to work in General Management roles, then look for colleges, who specialize in General Management. Similarly, if you want to go into FIN roles, then choose your target schools accordingly.
Once you have the list of colleges, whose areas of academic strength coincide with your post-MBA goals, start prioritizing these colleges.
Visit the sites of these colleges, and see what they look for in their prospective candidates. Attend their online seminars. Talk with their Alumni. Lastly, keep in mind most of us want to land a good job after our MBA. So, do check their placement statistics.
