mau mau,
Ive just finished the CATS online course and found the course to be very good. Average 92% on all exams
I paid £999 for the online course and it included the groundschool, progress tests came free JAA question banks.
No doubt some will recommend other ATPL providers but i only have good words to say about the CATS system.
The price was one of the key reasons why i chose them.
good luck with your decision
