hindi naman. it is no different from review schools offering preps for the board exams in manila and elsewhere. yun nga lang para sa CGFNS ang review nila.
i guess the questions given are the same you will find in a nursing board exam cd that anyone can buy in the US. only thing is di yata available sa pinas yung review cd na yun, or di pa na-pirate. it is just a compilation of questions given in past exams, just like what you will find in any board review book.
