Hello Vishal,

The colleges or B schools are ranked by the method called rank methodology. It is basically based upon the merit and cumulative scores they have received. More the cumulative score, higher the college is ranked.

Basically here's what the number of letter A's mean:

• AAAAA: 95-99 percentile- Exceptional
• AAAA+: 90-94 percentile- Excellent
• AAAA : 80-89 percentile- Very Good
• AAA+: 70-79 percentile- Good
• AAA : 60-69 percentile- above average
• AA+: 50-59 percentile- fair
• AA: 40-49 percentile- average
• A+ : 35-39 percentile- satisfactory
• A: <35 percentile- pass
