Can I suggest you might get a more sensible reply
in the appropriate forum? The moderators might like to move the thread there, or Constelation might wish to repost.
For now the information I have. The UK sets exams once a month. The CAA website has
a list of approved schools. The groundschools are at the top of page 6 of part 1, contact details in part 2. "Res" means residential, "DL" distance learning.
