its a bit hard to study inside, unless, like they said, u get an
office job or something like that...
but even there, life inside just sweeps u away and your best laid
plans gets chucked aside... it takes a lot of discipline to keep to
your plans.
and besides, unless u go out of your way to be lam-nua, its not
likely that u will get too rusty... its all about exercising your
brain, not necessarily doing homework. read a book in your free
time, keep updated and talk to friends outside... that all
contributes to enriching u and preparing u for life outside.
its actually good to take a break away from studying for awhile...
it refreshes u and it makes u want to work harder after that cos of
all the time u lost.
the army as a choice of career, is often overrated... they pay o.k,
but its not for everybody... but NS as an experience, is often
under-rated. u just have to take it the right way and try to get
the most out of it.
and here's some tips for u:
nobody gets used to being dirty or life out in the field! but u
learn to take care of yourself and make yourself comfortable so its
not so bad...
a groundsheet over muddy ground is actually more comfortable to lie
on than rocky ground. grass is the best, but there are usually
insects. bring a trashbag. they're waterproof. your groundsheet is
not.
mosquitoes are everywhere, but u learn how to avoid getting bitten
(a little repellant over the ears so they don't buzz over them and
a little on your face and neck... not too much on your forehead cos
your sweat will wash them into your eyes and THAT HURTS. and
finally, a layer all over your uniform: sleeves, collar, helmet and
camo scarf.)
and last of all, have some self-respect... everybody gets tired,
but try to control yourself... nobody appreciates having a bitching
pussy in the section. u only end up pissing people off and STILL
tired...
u'll bore yourself stupid if all u think about from day one is
ORD... try doing what i do: wait for meal times 
its more predictable (at least while in camp...) and
u feel that time is passing...
