to tigabaguio- i am not sure if there is a prometric testing center in the philippines. you can check it online www.prometric.com if there is a testing center or you can ask the pearson vue testing center located somewhere in makati if they have prometric exam. you can check also online if when and how often they conduct the exam but i am sure that they do not offer review or refresher course because when i took my prometric exam here in doha, they did not provide us any reviewer or mention that they are offering refresher course but i am glad that i passed my exam.
