s surely all eligible candidates will recieve a call letter who's application is copmlete in all reguards. reg your % it is more than the min % i.e 60%.

PABT will be expained to you by the instructor in the AFSB or SSB and you can raise your querries to him.

i give you one clue, play the pc games for 2-3hrs a day and that will improve your quickness

all the best
good luck
