thanks for all the replies.
just felt that its a 3-way commitment i've got to shoulder.
army, girlfriend and studies. guess its either i make it or
break it.
well consulted my encik for advice and he told me not to worry
whether i get a 8-5 posting or not.
a lil about myself. am currently a technician and going
through my OJE now. so as far as i'm concerned, i'm not in my perm
unit as of yet.
thinking that its quite a fair bit of time being taken up
for studies so am really considering real hard. furthermore its not
really cheap to be enrolled into a priv uni. so can't really afford
to do badly 
U're in which AMB? In the past there was once B mech of 3AMB
were forced to stay in if they failed IPPT. No such news from the
other AMBs so you should generally be stayout but do note that for
technicians, OT is very common during periods of exercise/LAB etc
and its almost impossible to get leave/off granted during such
periods even if you have exams etc unless your WOIC or OC is very
generous and kind to you.
Anyway, as most technicians go, you are unlikely to change AMB
since where u OJE is normally where you end up in the end cos most
of them hate to retrain people as each AMB and even each workshop
may have slightly different work procedures.
