For the static station, it is usually two tries for shuttle run
and standing broad jump. If you achieve the passing grade
in first try, you still can try the second time. No changes
for this for many years. For pull up and sit up, it is only one
try.
For point 2, you can actually fall out and dun take 2.4KM, no
matter whether u failed or pass the static station. For ICT or
non-ICT IPPT, they will now keep ask you want to run or not. For my
last ICT, one whole group of ppl walk the first round and then all
fall out. Never complete the run at all. At Maju, the WO keep
saying that if you dun wish to take 2.4km, must at least complete
the 4 static station (fail also never mind), so that SAF can pay
you S$10.
