dont worry bout it too much mate, i have just turned 22, and i am actually stuck on my p's. i was given 3years with no points when i had just turned 18 (long story), then it got extended for no reason, when i went to get my licence back.
i have to wait until june 25th this year to go for my p2 test, but because i have just gotten into the navy, i wont be able to sit the test, as i can only come back to adeladie on weekends when i am not rostered on. they also won't let me do the test early.
my licence expires in december this year, which is when i was meant to be eligable for my full licence.
all in all, i got used to it, i got dealt with the raw end of the stick, but i wanted to drive, and this was the only way
cheers Bengi
