I wish you luck. Quick stat. for you. 70% of distance learners quit to go full time or fail.
The same for the flying side. Give yourself 4 months off with no other pressure. I have seen friends fail because they had to be back at work. That will cost you thousands and a black mark on your C.V.
Modular is just as good as Int. but working and studying is v. tough.
I did mod. full time in house. 5 of the 9 in there were ex. distance learners and more came along every few months into the school for various classes (not just the 2 week cram before the exam).
Those who do get all first time passes and work too....my hat goes off to you, cos you have earned a job at the end.
My point...it's not easy. Some degree students say it is harder doing the ATPL exams. If you are going to do it, go with Bristol GS. Their support is second to none.
Good Luck!
