ill throw in my understanding of the subject also!
I believe you have 6 sittings in which to complete all 14 exams. If you take more than 4 sittings for one exam (you fail it 4 times)....its back to the beginning.
If you pass all your exams first time you would have used 2 sittings (7 exams on one sitting, 7 on the other...or 8 v 6...how ever your chosen school operates) with 4 remaining sittings remaining.
So you only really have 3 sittings remaining to pass which ever exam(s) you failed (counting your initial attempt).
correct me if im wrong please!
*edited* its 6 sittings not my mentioned 5! thanks TenAndie! (i was the bloke infront of you at AA's assesments).
