Thank you all.
I will go modular and distance learning, yes. It sounds good to start with the PPL theory but to be honest I haven't decided yet whether I will do it in the US or Europe. So I'm searching for something that will benefit me for both options and in this case it's the ATPL theory since I will still have to sit the exams regardless of where I will train.
And I am actually considering your ATPL book
paco along with Bristol.
