now too late to apply already. but if you applied beforehand
[not too long ago lah, like a few months before], there is a
possibility of them egtting back to you, and if you're successful,
mindef will then send you another letter stating that you are to be
exempted from ns on one condition: that you remain as a regular in
the spf for a stipulated period of time.
if you have never applied before, then too bad lah. army it is for
you then.
