PilotOnline,
I'm in the same postion as you - need brush up with the old maths. Haven't really done much since 'O' Levels many, many years ago.
Strangely enough I posted almost the exact same message on the Bristol forum two days ago.
I'm planning to start my ATPLs in September (subject to the Class 1).
I been doing some research about the maths side of things and found the Letts Revision Guides website seems to have some useful stuff -
http://www.letts-education.com/index.jhtml - got some good links from it also.
What route are you planning to take with the ATPLs - Int or Mod?
I see you're in London, PM me if you're interested in hooking up and having a chat.
Paul
