Don’t forget you have to get your flight training completed within 3 years of passing your first exam.
My advice if you’re thinking of delaying...
From the date you passed your first exam you have 18 months to finish all of them so study for your ATPL’s as normal and take them in May but leave the easiest left exam out.
Take that exam on the 16th month from passing your first (just in case you need to retake)
Then you’ve got the maximum time available to do the CPL/ME/IR if you need to delay
i did the exact same thing but for financial reasons.
if you’re thinking “I’ll just get it done” be very cautious because when you’re 2-3 IR Renewals in, it gets harder to get a job when you’re competing with people fresh out of training.
At the end of the day it’s a gamble whatever you choose but good luck !
