In order to attempt GMAT through test centers in bangalore there are two options
1) Pearson test center at JPnagar
2) Pearson test center at Cubbon road.
As I have been to both I would like to give a short comparison in terms of accessability and facilities.
First the Pearson test center at JPnagar is located at southern side of bangalore near silkboard. Its accessible through the yellow and green line metros but with little walking extra! The location is bit off from the main road hence traffic and ambient sound was a bit lower
The second one at Cubbon road is at walkable distance from MG street metro station(Violet line). Compared to the former its located at the heart of city and on the main road.
The facility is top class. Though bit noisy at out inside the center its damn quiet.
Those going to take GMAT depending on the availability of slots an chose the best that suits them.
