this napfa was held on a day with:
1) little wind, shiok
2) no sun
3) no rain
4) cool weather

therefore everyone were in their best shape =D
but, i didn't retake!
not to regret or what, i paced junlong for his 2.4 =D
and able to help him get a C grade which was equivalent to gold, good for him.
a silver or a gold wont make any difference when enlisting as its still -2months!
i'll stick to the silver =)
and i'm willing to run together with anyone for the retest.
good luck everyone! jiayou!
