i managed to pass with incentive during last window. does that mean that this window even if I go to IPT IPPT and end up with band 1, I will still have to pass the IPPT standard?
Ya, follow your band.
Dunno if they changed the system, but last time for 5-station IPPT, I recall that at most they will let you go is one band down. So if your last window was pass, you will likely be band 3, assuming the rules for this PPT thing didn't change.
But if you could pass last window, and think you still can do it, might as well pass the IPT IPPT, you can straight away clear it I think.
