Just doing DL full-time can mean it takes 4 months (2 months for each module).
Bearing in mind that there's two weeks' compuslory ground school, plus one week of exams for each module, that must have been a superhuman effort! I've spent four months full time just on module one so far - three and a half months working through the course material and two weeks using the question bank - and I've still got the ground school fortnight and exam week to go. I hope to cover module two quicker but 5 weeks? Heavens man, did you never sleep?
