Well not sure how many replys you will get as a lot of people from atlantic will obviusly be sponsered.
Ill answer anyway.
Firstly I too was a sponsered cadet but only in the 50/50 department not the fugley so ill not be too bised towards them.
OK ground school wise, they have got some good instructors both air and ground that do know there stuff.
On the ground side, I did it modular distance learning while working (That will be a big clue to those at Atlantic as to who I am).
When ever I had a question, I almost alway had an answer that day by email if I sent one by email, and by phone there and then if I rang up. If it was a question they didnt know the answer for immediatly they went and found the answer for me.
The material has changed since I was there so I cannot comment on that side.
Flying wise.
This can depend on your learning style, but I had no problems with the way I was tought in the air, very proffessional and knowledgable in that department, with good debriefs on what you have done wrong and what you need to do to get it right.
Only thing you might find which ive found in many places is that time might slip so you might be later than you wanted to get airborne, but with aviation ive always said to everyone dont expect the weather or aircraft to be perfect all the time, dont expect the insturctors to be always on time as where ever you go thing do go wrong.
Overall they are an ok bunch.
And just remeber AFT train the cadets that are going to fly for AA so there training may seem tough but its too make sure you can handle yourself when and if the time comes.
Good luck with your exams and training.
