can someone tell the batches of resonance from highest badge to lowest badge

There are upto 40 batches of class 11 at resonance. These batches are distributed among few series like A series, B series and Q series. These series are based on how early a batch starts. A starts first in april,then B in may end and so on. Now each series has different batches A series has about 12 batches and B series has 7 batches. These individual batches are arranged as per student's performance in tests(It may be admission test or regular tests conducted by institute). For example A1 students acquire more marks than A2 students.

The capacity of students and number of batches keeps on increasing every year.
