The training at BGS is about half way through the basic phase. For me this is 7 months into the NZ course, but i am on the long foundation course.
As far as im aware, its 2 weeks revision, then 1 week of exams.
The second set of exams are after the basic phase (about 2 and a half months more) and is in the same format as before. That being 2 weeks of study then 1 week of exams.
Im not so sure about the "training" though. I was under the impression that the ground school was all distance learning, and that the 2 weeks prior to the exams were revision weeks, rather than actual training or learning sessions.
