GCTS
I have just finished the DL course with Gulf coast, I also looked at NAC before deciding on GC. The main thing at the time that made me choose GC was Steve Gibbin's knowledge of the subject and the time he spent with me to help me understand the process.
NAC really did not impress me on the phone with there knowledge of the process which is important when your trying to demystify the CAA.
As far as Ipad, the manuals can be downloaded as PDFs and you can currently go online for the question bank. They were working on the Ipad offline version a while ago so i assume its close to completion.
Steve Gibbin is easy to chat with so I suggest you call him 188 966-2875 or 1 772 672 899.
I would recommend them, don't hesitate to ask e more questions.
With the distance learning and a 1 week brush up in Ft Pierce before exams I completed in 3 sittings with and average of 89% no fails.
I put this down to a lot of time sitting in my study and Steve's tireless help explaining things I was stuck on.
