Which is the most Suitable Coaching for me

I have recently cleared my PCC and my attempt is due in 'may 11'. I can join classes anytime after september anywhere in India.

My preferences in choosing Coachings are as below-:

1) Where class strenght is lesser than 100 (or if the number of students exceeds in a class, There must be a doubt clearing session or facility)

2) Which finish the course upto march, 11.

 Pleses suggest me best coaching centres alongwith Their contact details. I'll be glad..
