1st phase RT is twice a week for 4 weeks( 1 weekday and 1
weekend), 8 session take test.
Discharged if you pass.
Otherwise 2nd phase RT(9-20 sessions), I think is thrice a week for
4 weeks(2 weekdays and 1 weekend), at the 16 sessions ,you will
take the test again.
Pass you will be discharged, if you fail ,you need to complete the
20 sessions(total 8 weeks).
So after the 20 sesssions, you will be considered to have completed
your obligation for the window before, but since you have not pass
your IPPT during RT , you still need to book for IPPT for the new
window.
If you have passed your IPPT during the RT, it be will considered
as you have passed your IPPT in the new window & even monetary
award if you make the mark.
For eg, at age 27th window, you have failed your IPPT after many
tries, so you book for RT within 2 months after your 28th birthday,
went for the RT, let's say you pass your RT's IPPT at the 16th
sessions and be discharged. You are also considered to have pass
your IPPT for your age 28th window.
