Hi Peter,
Same as above.
Most schools will teach you the ATPL syllabus over 2 modules. Each module will have 6, 7 or 8 subjects (mine is split 7:7, Bristol is 8:6 iirc).
However Cabair do split their ATPL distance learning over 4 modules, each with 3 or 4 subjects and thus exams at the end of it.
Personally I like the 2 modules as it'll give you plenty of time and spare sittings to pass any resits that you may have to undertake.
Best wishes,
Charlie Zulu.
