PPL Groundschool
Banksy,
It would help if you told us whether you intended obtaining a JAA PPL or an FAA PPL.
If it is the FAA one, you should be able to take your exams at Flight Training Inc at Farnborough (I know you can do the CPL ones there). If you want groundschool training for FAA PPL, I think Linda True may do it, (I know she does IR). She sometimes advertises in the small ads in the flying mags. I think she calls her company True Airspeed: do a search on this website and I'm sure you'll find her. You can get a fair amount of FAA study material at Transair.
If you are looking at JAA PPL, I believe Derek Davis at Bournemouth (among others) does PPL groundschool on a residential basis, one subject per day (hard work but a quick way to do it). Derek regularly advertises in small ads in the flying mags.
Good luck.
