Hi
I did in 9 months distance learning - doing it in three sittings - 5 + 5 + 4
I used the oxford books + britsol question bank
In general I didnt look at the bristol question until I had gone through the books, concentrating on the chapter questions instead
However for some exams for example air law and op proc i did consult the QB to try and get a feel for the type and depth of questions i might get for a particular subject
Then once that was done .. used QB for revision - to highlight areas where I was weak and need some extra work
Final few weeks 100% QB
This worked for me ... with an average of 96% over the 14 papers
Good luck anyway ..
Best cheer Neil
