GMAT Strategy

Hi,
Would like to know about the various training centers in bangalore.
I have heard of csquarelearning, which comes highly recommended, from various blogs and topics.
what are the other options
the info i am looking for:

1) the fee
2)flexibility: in terms of letting me decide which areas i would like to work on.
e.g quant. is my major worry for now, and thats what i would like to get trained on. please do share your experiences.
i am taking the test on aug. 29 . i cant therefore wait for some regular sessions that might begin in july for example. am looking for an institute that can tailor to my requirements. any pointers welcome.

Thanks
warm regards
