I believe there are people in Bournemouth that may help you in case you need any help.
Bournemouth is also home to GT-Serv Groundschool, another high quality but less known ATPL provider. You should check them out.
GTS Groundschool
BCFT has a full-time ATPL groundschool and they should be using Bristol GS notes.
EDIT
Disregard about GT-Serv, apparently they don't offer any ATPL course anymore. Does anybody know why?
