Kebab kid,
I believe there are a few guns out there who have done so.
I am currently doing the first 8 subjects of the Bristol course (Module 1), start date 3/9/03 finished content 6/12/03, revision (at home) start 9/12/03, aim to finish 6/1/04, then practice exams until the class revision and exams. I also work full time, fly about 600+ hrs per year.
How much time you can spend on it is obviously the major factor, also your level of dedication and understanding. It's hard, but do-able.
As far as exam difficulty, at a guess, comms and human factors could be straightforward. If I could, I would defer Instruments and Met indefinitely
