Hi John,
In a similar boat to you really and fully understand where your coming from. I m looking to start my PPL in May time but im down on the south coast and my biggest worry is the ground school. Not great reader and learning stuff from books so like you also asked about on here and other forums when I posted got abuse cause I used to many ! so dont take that to heart.
Try this company
The Great Circle - PPL Exams | Pilot Training | Ground School - The Great Circle found them when I was looking so I migth book in with them when I come to start. Could be a bit far for you though.
Have you started your ppl?
Kev
