eh this part i dun get it
what is IPT and IPPT?
all the while i just take IPPT 
IPT= IPPT Physical Training.
So-called 'pre-RT' for those NSmen who seriously think that they
cannot pass IPPT. Must clear eight sessions within five weeks, and
the eigth session is the actual IPPT test.
Those who clear those eight sessions will be protected from RT
even if they fail their IPPT.
The catch is that it's voluntary.... ergo, it's unpaid (except
for the 8th session), and it does not count towards the 40 days of
NSmen liability.
The way I see it..... better go for 7x unpaid tekan session than
risk 20x paid tekan session. Time lost going for RT is much worse
than money gained from it.
Besides..... the PTIs are pretty understanding people, if you
get my drift.
