IFTA/EFT
I did my ME/CPL with IFTA last year and had no problems with them as I achieved everything I planned in the minimum hours and time and most importantly got a first time pass.
Regarding the first time pass rates, i believe they both are very good. They seem to be using the same examiners from the uk for both schools, this was the case when I was there, the examiners were travelling from one school to another.
Good luck for the training, enjoy it!
