Anyone started taking driving during SIP (Poly) but never pass the pre enlistment IPPT thus need go in early but still managed to complete the driving stuff before NS?

Cuz the thing is almost managed to pass second try by like a too close timing that it is really tilting if I have to go through the entire thing again. Retraining again and what not.
So my point is if I'm still able to complete before or during NS then I have no other worry. Any good opinion? Cuz if it turns out not much of a difference to go for PTP and still complete the driving stuff then I guess its not too bad + heard u still get allowance pay during PTP.
