Thanks fof the advice but then when i called the Hospital i was going to apply they told me that I am also qualified to work eventhough Im a GC holder only. I tried browsing in the internet and this is what it says:
There is no longer a single Civil Service Exam to cover all government jobs. Moreover, many jobs with the federal government no longer require written tests. To find out if a particular job opening requires such a test, contact the listing agency's personnel department for further assistance and guidance.
But then the hospital i'm going to work really requires it. I also looked it up 3 days ago and found no answers when the dates of the next exams would be. Im really sad! I really wanna work in the Government Hospitals here.
