ALFA, as far as I know it's 36 months from the date of one partially passing the first lot of groundschool exams.
And you need both CPL skills test and IR passed within this time.
I know the feeling, I was in the same position last year. Got the lot with two months to spare!
Give CAA FCL a ring ASAP. You don't want to do that lot all over again! <img src="eek.gif" border="0">
All the best.
