There is no cutoff or failing grade for PILAPT, so don't worry about that assessment... check the company website for more information.
A very important factor to keep in mind is... your time. Ask how many cadets are waiting ahead of you for the Line Training; what would be your exact start date; etc.
Its good you're asking the questions, doing the prep work. Make sure you have a plan B, too.
ABY won't take cadets if it doesn't need them. Another recession, another war, another SARS event - anything can happen*.
