generally there are 2 kinds of enlistees who end up in OCS (but
with the impending changes, this may change too since everyone
would end up in SISPEC first)
1. those who die die want to go to OCS, and do their best and well,
get what they want.
2. those who are more nonchalant, but ended up in OCS anyway.
as is clear, the first batch of people are highly motivated cause
of their aim. the reasons for that aim are another story.
for the second, its more like - if have go lor, if not also never
mind.
so in asking your question, you seem to imply that you are not in
the first batch, but at the same time, you have a choice too.
chances are, you do have certain influence, but the decision in the
end lies with your superiors. so if you cannot find reasons to
motivate yourself like the first group of people, whether you end
up in OCS (or SISPEC for that matter) may not be up to you. i dont
think if we recommend going to these schools, you would suddenly
find a strong desire for them. if you had this desire, this
question wouldnt even have came up.
so after all that, the first question should be why you want to go
to these schools, if you want to at all. we cant help you with
that. perhaps after that, we can then examine (if it is still
meaningful) what goes on in these schools - whether its hell or
not.
