wonder if i m too late to reply. lol. for ur info, u must be
serving inside the police force, to apply for selection into the
S.T.A.R. u can apply for S.T.A.R once u r in TRAcom, don need to
wait after u post out of PA. so, is still 5 o level credit.
however, those without 5 credit, can also apply, Those with less
than 5 GCE 'O' level credits will be considered on a case-by-case
basis. (is written on the webby.)
