Key factors -
Location - It is quite far from OMR Road. So, I had to travel for around 2 hrs to reach center.
Ambiance - Ambiance is good. There was no external disturbance and controllers were co-operative.
Technical - Computers were Good.
As this is a pearson centre , everything went well. Exam started at right time. Proctors were very helpful. Higly recommend this Centre in chennai. Air Conditioning is good. You can have snacks during breaks. They will not allow you out during break. They are asking for passport. Not sure if they allow you without passport.
