In what way??
I've really enjoyed them.
I've just realised the syllabus is now online:
http://www.abrsm.org/?page=exams/jazz/jazzFlute.html - that'll give you an idea about what pieces are on the syllabus.
The divisions (blues & roots, standards, contemporary) are the same as in other jazz horn exams.
Most of the G1 pieces only have 8 bars or so of improv. There are chord symbols and guide notes in each improv section.
There's quite a wide variety of pieces. My favourites from the G1 lists are:
Someone's Knocking At My Door, & St James Infirmary
Moonglow, & Bye Bye Blackbird
Everything That Lives Laments, & Mo' Better Blues
Some gospel-y ones, some classic blues, some Latin, lots of variety esp considering there're only 15 pieces in the book! Some well known names like Reinhardt & Grappelli, Miles Davies, Keith Jarrett.
Each piece has a little bit of history/notes about the composers or the piece, and a suggested track to go away and listen to.
Not much in the way of trying to teach improv, besides the guide notes - if I hadn't've had the session with Violinia I would have even less of a clue than I currently do

That help at all??
